Let’s not kid ourselves, Postmark is a great email service in almost every regard. However, if you’re reading this, the chances are that it doesn’t fit your needs anymore, and you’d like to switch it up a little bit.

Luckily, you’ve come to the right place! I’ve interviewed our very own deliverability experts whose opinions are based on the latest state of the industry and years of experience, took their recommendations, tested every platform I mention in this article, and these are the results!

  • Mailtrap is the best Postmark alternative for product companies with large sending volumes looking for high deliverability and industry-best analytics.
  • Mailchimp is most suitable for small businesses on a budget who need both email marketing and transactional messaging features.
  • Mailgun is a solid choice for experienced developer teams since it’s, as its creators say: ‘made by developers, for developers.’
  • SendGrid offers an email marketing suite and SMTP/API services with rich documentation, but has customer support locked for high-tier plans.
  • Amazon SES is a great Postmark alternative for experienced developers who are already in the AWS ecosystem.

Postmark alternatives comparison criteria

Before we get into actual Postmark alternatives, let me share the criteria I’ve used to come up with the list.

I’ll describe the aspects I’ve benchmarked, provide the comparison tables I came up with, and more. This way, you get a 100% unbiased review with no sponsored links or content, just results from many hours of testing.

Email infrastructure

A solid email infrastructure is the backbone of every email service provider out there, and it consists of deliverability, reliability, and scalability.

Deliverability

Every email that doesn’t reach your recipient’s inbox costs you $0.11, so deliverability, or the platform’s actual ability to have your emails land in the main inboxes instead of going to spam or promotion folders, is crucial.

For example, to have your emails hit the mark, Postmark has strict sending policies in place, uses worldwide data centers, provides separate streams, dedicated IPs as add-ons, and a few other bits and bobs. 

So, I’ll compare what other providers offer in this regard and what they do to help you reach your recipients’ main inboxes.

I’ll also provide you with deliverability rates some of the providers on this list achieved on our recent deliverability tests we performed using free plans, same templates, and shared IPs. Here are the results:

Email service providerEmail placement result
MailtrapInbox: 78.8%
Tabs: 4.8%
Spam: 14.4%

Amazon SESInbox: 77.1%

Reliability

When we’re talking about reliability, we’re talking about whether an email service provider is able to consistently deliver your emails without any major hiccups. Additionally, an ESP shouldn’t face delays or downtimes and should offer transparent monitoring of these issues.

For instance, SendGrid advertises a 99.99% uptime, and I was able to see whether this is actually true by visiting its status page

Scalability

Scalability is the ESP’s ability to grow with your business, that is, to allow your business to grow without facing bottlenecks, degraded campaign performance, or other major issues.

To be scalable, an ESP should offer some of the following:

  • High sending throughput
  • Cloud-based infrastructure
  • Dedicated IPs or streams
  • 24/7 customer support
  • Email deliverability consultations

Separate sending stream

As you already know, Postmark offers dedicated sending streams, which you can use to send user-triggered and bulk emails separately.

Now, true separate sending streams are quite rare nowadays, so, on this list, you’ll only see a couple of ESPs that offer them, while the others provide you the tools to separate your streams.

Here’s a quick breakdown of each:

Postmark alternativeSeparate sending stream
Mailtrap✅ Has a dedicated bulk stream and a bulk-aware email API
Mailchimp❌ Not a separate sending stream, but it’s doable by using different domains
Mailgun❌ Not a separate sending stream, but it’s doable by using different domains
SendGrid❌ Not a separate sending stream, but it’s doable via IP pools or subusers
Amazon SES☑️ Not a separate sending stream, but it’s doable via dedicated IPs and configuration
Brevo☑️ Supports separate sending for transactional and marketing emails via different SMTP/API endpoints

Pricing comparison

To help you decide whether an ESP from this list is more affordable to you compared to Postmark or not, I will break down:

  • Different pricing plans and features they bring to the table
  • Price per sent email compared to Postmark
  • Key pricing differences between each provider and Postmark

And here’s a table for you to get a brief idea of the Postmark alternatives pricing:

Alternative10,000 emails50,000 emails100,000 emails250,000 emails

SendGrid$19.95$35$60$200
Amazon SES$1,00$5,00$10,00$25,00
Brevo$17$55$69Custom

Transactional email sending

To help you send transactional emails easily, that is, welcome emails, password resets, etc., Postmark offers an SMTP server with pre-made snippets and a flexible email API

So, in this article, I’ll list ESPs that offer similarly rich documentation and APIs that support integration with major programming languages. In case you’re an API heavy user and need a plethora of integration options, here’s a breakdown of supported libraries for each provider:

Marketing email sending

Marketing email sending is quite a different story from transactional, since you’re sending campaigns instead of user-triggered messages. Currently, Postmark doesn’t offer this functionality.

In case you’re transitioning because of that, I’ll list some ESPs that can help you optimize your email marketing funnel, namely:

  • Manage your contacts
  • Track performance metrics
  • Perform A/B testing
  • Automate workflows

Essentially, these are just the features you can use to grow your business via email marketing.

AI, automations, integration

AI in email marketing

AI in email marketing has stopped being a gimmick a while ago. For example, Postmark offers MCP servers, with which you can prompt your AI assistants to send emails, use templates, track performance metrics, or even manage whole campaigns in your stead.

Moreover, ESPs have started integrating AI for audience segmentation, generating subject lines or even email content itself. 

So, I’ll make sure to point out useful AI tools I tried and tested throughout the reviews.

Integration

Although Postmark doesn’t offer many integrations, it has several useful ones, like the one with ActiveCampaign, its parent company. You can use it to get some basic email marketing functionality, then pair Postmark with Mailcoach or Craft Campaign to take your campaigns further.

However, if you’re looking for advanced integrations, I’ll be mentioning ESPs on this list that offer them.

Email design

Coding email designs has long been a thing of the past. Most ESPs nowadays offer some of the following features to make your email creation process as seamless as possible:

  • Drag-and-drop editor – A solid drag-and-drop email builder lets you arrange your email according to your preferences, tweak the layout, preview mobile and desktop versions, and more. Everything without having to go anywhere near your HTML code editor.
  • Email templates – If an ESP doesn’t offer its own native templates, it at least provides an integration for them. For this article, I checked not only how many template options you get for each ESP but also how good-looking they are.
  • Sandbox mode – With a sandbox mode, you can safely test your emails before sending them, without worrying that you’ll spam your recipients. So, instead of sending out your emails beforehand, you can just inspect them, see how they fare with spam, and more. 

User experience

An ESP should make your life easier, not harder, especially if you’re transitioning from another solution. That’s why, when writing these reviews, I always ask myself the following questions:

  • Is the platform user-friendly? Is it oriented towards marketers or devs?
  • How can I reach the platform’s customer support, and when are they available?
  • Do I get any migration help if I’m coming from another service?
  • Can I consult with the platform’s deliverability experts?

To sum it up and answer these questions, here’s a nice little table for you:

Amazon SES🌟Ticket, email, chat, and phone24/7✅ (via AWS migration tools)✅ (requires AWS Enterprise Support or TAM)
Brevo🌟🌟Live chat and phone24/7 for some plans☑️ Enterprise plan only

Customer experience

Postmark is quite transparent in terms of its customer success stories on its homepage, so I’ve checked what users have to say for each ESP on this list.

I’ve scoured online customer testimonials and reviews on websites like G2 and Capterra, and even checked social media. There, I was able to learn a great deal about the platforms, including whether they have been facing downtimes, unresponsive customer support, and more.

Most importantly, I tried to find reviews from people who have transitioned from Postmark to see what made them migrate and whether they’re satisfied with the transition.

Security

To see how each ESP on this list handles security aspects like DMARC protection, API key security, event logging, authentication, etc., I checked pages like this one, for example. 

Here’s a quick summary for you:

Compliance

If you want to remain compliant with all the email marketing laws like GDPR or the CAN-SPAM Act, you need to switch to a provider that will make it easy to do so.

Best Postmark alternative: Mailtrap Email Delivery Platform

G2: 4.8 🌟 Capterra: 4.8 🌟

Mailtrap Email Delivery Platform is designed for product companies with high sending volumes. It’s best for businesses that need high deliverability rates, growth-focused features, and industry-best analytics.

Notable features:

  • High deliverability rates

Mailtrap places a strong focus on helping its users achieve high deliverability rates and land in their recipients’ main inboxes. It achieves this by offering dedicated IP addresses, domain or IP warmup, throttling, and, similar to Postmark, dedicated sending streams.

Here’s how Mailtrap performed compared to Postmark in our recent deliverability tests:

  • Growth-focused features

Mailtrap offers a fast-scaling infrastructure that allows fast-growing businesses to increase their sending volume without experiencing any delays, issues, or drops in deliverability rates.

You can even contact the platform’s deliverability experts to fine-tune your sending configuration, set up webhooks to listen to various events, and more. Additionally, I have to mention that Mailtrap’s customer support is available 24/7 for all plans, so you can count on their help in case you face an unexpected blocker.

  • Industry-best analytics 

With Mailtrap, you can observe the performance of your emails through helicopter-view dashboards and drill-down reports. There, you’ll be able to see your opens, deliveries, unsubscribes, bounces, and more.

Additionally, you can see how your emails are doing with each provider.

How is Mailtrap different from Postmark?

The biggest difference between the two platforms is that Mailtrap offers a suite of email marketing tools. You can use these to upload your contacts, create an email template, schedule a campaign, and then track its performance after it’s launched.

Another difference is that, unlike Postmark, Mailtrap provides its users a full-fledged sandbox for testing emails. You can use it to see how your emails look on different devices, what their spam score is, and more.

Lastly, although Mailtrap offers separate streams like Postmark, you cannot make custom ones for different types of email. Instead, you get a separate stream for transactional emails and one for bulk emails, which allows you to send user-triggered and promotional emails at the same time without sacrificing your deliverability.

Security

Both ESPs enforce TLS 1.2+; however, Mailtrap also supports MTA-STS, which offers slightly stronger protection. Additionally, Mailtrap gives you more granular control over API keys and monitoring.

Pricing

I’d say Mailtrap’s pricing plans are quite scalable, with the Business tier having pretty much everything you need with a more-than-decent email limit. Check them out:

Mailtrap vs Postmark pricing

Here’s how Mailtrap compares to Postmark in terms of email limits:

Price for MailtrapPostmark
10,000 emails$15$15
50,000 emails$20$55
100,000 emails$30$100
250,000 emails$200$250
700,000 emails$300$455

Key pricing differences

  • The biggest difference between the two platforms is that with Mailtrap, you get dedicated IPs starting from the Business plan, whereas with Postmark, you need to be sending at least 300,000 messages a month just to be eligible for a $50 add-on. 
  • Allowing you to send up to 3,500 emails per month (150 max daily), Mailtrap’s free plan is one of the most generous out there. Especially compared to Postmark’s free plan that lets you send 100 emails/month.
  • Mailtrap doesn’t allow overages, whereas with Postmark, you can pay an additional 10k emails for $1.80, $1.30, or $1.20, depending on your plan.

P.S. If you’re looking to migrate from Postmark to Mailtrap, read our dedicated migration guide.

Customer experience

One of the first Mailtrap reviews I stumbled upon on Twitter was from a user who migrated from Postmark, saying that it’s a cheaper solution with better analytics and helpful customer support.

Reviews on Capterra and G2 were mostly positive, like the one in the screenshot below, with remarks on Mailtrap’s deliverability and dev-friendly API.

Mailchimp Transactional Email 

G2: 4.4 🌟 Capterra: 4.5 🌟

Mailchimp is one of the oldest names in the industry. It started out in 2001 as an email marketing platform, launched Mandrill as a transactional email add-on, has been acquired by Inuit, finally evolving into a full-fledged email delivery platform.

Now we have Mailchimp Transactional Email, a part of Mailchimp most suitable for small businesses on a budget who need both marketing features, on top of being able to send transactional emails.

Notable features:

  • Pay as you go

When I say Mailchimp is most suitable for small businesses, it’s mostly because the platform offers a pay-as-you-go plan. You get all the essential features you need to start sending transactional emails. If you run out of them, you simply buy more credits.

Additionally, Mailchimp’s free plan is also generous in terms of the features it offers. Namely, you get limited email sends (1,000 per month and 500 contacts), but you can create surveys, landing pages, and more.

  • Integrations

Mailchimp probably has the richest integration catalogue on this list, allowing you to connect your project to accounting tools, social media platforms, e-commerce shops, and more. 

There are two dozen categories you can use to sort through Mailchimp’s integrations, with some of them being available completely for free (e.g., Shopify, WooCommerce, Typeform, etc.).

Source: Mailchimp
  • Email templates

Mailchimp offers more than 130 templates for all sorts of email campaigns. From basic newsletters and welcome emails to seasonal and announcement emails, you name it.

Additionally, if you have your own HTML emails you used at Postmark, you can import them to Mailchimp, edit them directly on the platform, and send them off.

How is Mailchimp different from Postmark?

Besides keeping your email logs for a shorter period of time than Postmark and having an email marketing suite, Mailchimp also provides AI tools, which Postmark doesn’t. Namely, Mailchimp has AI content helpers, optimizes sending times with AI, and even has predictive analytics.

Cons

  • Can become pricier, especially if you plan to send both transactional and marketing emails.
  • When compared to other email service providers, especially Postmark, Mailchimp has a slightly higher learning curve due to its complex interface. 

Security

Here, Mailchimp offers broader API authentication with OAuth 2.0 and provides audit logs only for end-tier users, compared to Postmark, which enforces stricter access controls.

Pricing

Free plan: 100 emails per month 

If you visit the Mailchimp pricing page, you’ll notice that it’s not as simple as Postmark. Namely, Mailchimp has separate pricing plans for its email marketing suite and for transactional email. 

Mailchimp Email Marketing

Mailchimp Email Marketing Plans are based on the number of contacts you have. Although I must note here that there is a significant increase in price if you have a big list, which is another reason I recommend Mailchimp for small businesses

Nonetheless, here are the price ranges you can expect:

PlanMonthly CostEmail LimitContactsKey features

For more details, please consult the official Mailchimp pricing page.

Mailchimp Transactional Email

For transactional emails, Mailchimp again lets you choose your sending volume and bases your final monthly subscription based off of that number. However, you don’t get any of the previously mentioned marketing features.

Here’s how it compares to Postmark:

Price for MailchimpPostmark
10,000 emails$20$15
50,000 emails$40$55
100,000 emails$80$100
250,000 emails$200$250
700,000 emails$504$455

Key pricing differences

  • To get a dedicated IP from Mailchimp, you only pay an additional $29.95 per month and don’t have to send a certain number of emails to be eligible.
  • Unlike Postmark, which offers 45-day email logs on all plans, Mailchimp limits them, along with advanced analytics, to higher-tier plans.

Customer experience

Users find Mailchimp a great option for small businesses, which is no surprise when you consider its pricing model.

Other users like its email marketing integrations, analytics, and dedicated support. However, there are some remarks about the template editor being clunky, which is a bit true since Mailchimp does have a tricky UI.

I have also found some friendly banter between the two yellow-heavy platforms on X:

Mailgun

G2: 4.2 🌟 Capterra: 4.3 🌟

Mailgun is a transactional email delivery service with SMTP and API solutions geared for developers.

Notable features:

  • Rapid Fire Delivery SLA

For enterprise users, Mailgun offers Rapid Fire Delivery SLA, which comes with a promised 99.99% delivery rate even for volumes of 15,000,000 emails per hour. It’s also optimized for sensitive emails like 2FA codes or login links so that they’re sent with minimal latency.

Although this is one of Mailgun’s selling points for high-volume senders, it’s important to note that it doesn’t promise inbox placement, rather just the email handoff to the recipient’s server.

  • Solid webhooks

Available on all plans, including the free tier, Mailgun’s webhook API can be configured to notify you of email deliveries, opens, bounces, etc. It’s also configurable at the domain level, which makes it a solid choice if you have multiple domains.

Additionally, Mailgun’s API has solid retry logic and will retry failed deliveries for up to 8 hours. This makes it quite reliable for tracking events and minimizing issues in cases where your server might be under a heavier load than usual.

  • Email validation

Adding email validation logic to your web forms significantly reduces bounce rates and improves your list quality. Mailgun offers a validation API for this, which checks your new sign-ups for basic syntax errors, disposable addresses, typos, and more.

You get validation credits on all free plans, and you can pay $0.80 for additional validation charges.

How is Mailgun different from Postmark?

In contrast to Postmark, Mailgun offers a standalone testing/deliverability solution, Optimize. The suite includes the aforementioned validation API, has inbox placement tests, email previews, reputation & blocklist monitoring, Google Postmaster Tools integration, and more.

Mailgun also gives you more room for customization over your sending infrastructure than Postmark. Namely, you get full control over sending IP pools and domains, granular log retention, etc.

Lastly, if you want to spice up your email game a bit and launch a marketing campaign on top of sending transactional emails, you can integrate with Mailjet, which is a brand under the same Sinch roof.

  • Developer-friendly
  • High sending throughput
  • Onboarding support
  • Real-time tracking
  • HIPAA support
  • Inbound email routing support
  • Marketing features via Mailjet integration

Cons

  • Higher learning curve than Postmark, requires previous developer experience.
  • A lot of useful features like deliverability consultation are locked to end-tier plans.

Security

While both platforms enforce strong encryption protocols and handle security well, I should note that Mailgun offers more granular API key management and user permissions. It also focuses more on reducing bounces and spam complaints, but those are just minor differences.

Compliance

The key difference here is that Mailgun supports HIPAA with a BAA, whereas Postmark does not. Besides that, both are similar compliance-wise:

Pricing

Free plan: 100 messages per day during the first month

Mailgun vs Postmark pricing

Price for MailgunPostmark

50,000 emails$35$55
100,000 emails$75$100
250,000 emails$215$250
700,000 emails$550$455

Key pricing differences

  • Although Mailgun has slightly more expensive plans in general compared to Postmark, it includes dedicated IPs once you get past 100k emails per month.
  • Mailgun also offers a bunch of quality-of-life features in higher-tier plans, like link tracking, uptime SLA, dedicated IP warm up, and others.
  • Mailgun has limited log retention for lower-tier plans, whereas Postmark gives you a full 45 days even on the starter plan.

Customer experience

I’ve noticed that Mailgun has mixed reviews on social media, but it seems to be praised by verified users on websites like G2 and Capterra. Its API gets a lot of love, and the fact that Mailgun helps you comply with inbox provider policies.

Others like its WordPress integrations, but are not the biggest fans of extended logs being available only to high-tier plans.

SendGrid

G2: 4.0 🌟 Capterra: 4.2 🌟

SendGrid is an email delivery platform that offers both an email API and SMTP for transactional email sending, as well as a suite of tools for sending email marketing campaigns.

Notable features:

  • Deliverability features

SendGrid uses a cloud-based infrastructure, provides geo-specific IPs and reputation monitoring tools, Deliverability Insights for tracking email performance, and more. Overall, if you have a team of developers who can put these features to work, you won’t have to worry about deliverability much.

However, if you don’t use SendGrid’s deliverability features, here are the email placement results you can expect from it, especially if you’re on the free plan:

  • Rich documentation

Even though SendGrid is not strictly geared for developers, like Mailgun, for instance, I have to admit it has super extensive documentation. It covers both transactional and email sending, has a plethora of examples and snippets, as well as quick-start guides.

  • Email marketing suite

SendGrid covers all email marketing bases, from drag-and-drop editor and templates to marketing automation workflows and a wide range of integrations. 

However, I must note that you need to pay for a separate plan to use the email marketing features.

How is SendGrid different from Postmark?

The biggest difference between the two platforms is that Postmark doesn’t have email marketing features like drag-and-drop editor, automation workflows, and similar. However, when it comes to transactional email sending, both platforms do their job quite well.

SendGrid offers a testing suite for inbox rendering and checking spam filters. On top of that, you can validate emails with SendGrid, whereas you cannot do so with Postmark.

Pros

  • SMS support via Twilio

  • Global data centers
  • Marketing tools
  • Detailed analytics
  • Plethora of integrations

Cons

  • The free plan is a bit limited, but at least it’s not as limited as Postmark’s.
  • Customer support is a bit limited, and you will get faster response times if you’re a Pro or Premier user.

Pricing

Free plan: Up to 100 emails per day for the first 60 days

SendGrid has two separate pricing models: one for its email API and one for its marketing campaigns. Considering you’re a Postmark user looking for an alternative, here’s SendGrid pricing plans for the platform’s email API:

250,000 emails$249$250
700,000 emails$499$455

Key pricing differences

  • SendGrid is a bit more expensive than Postmark but comes with more advanced features starting from mid-tier plans. These include SSO, deliverability optimization, dedicated IPs, etc.
  • If you want to send more than 1 million emails per month, SendGrid is about $100 more affordable.
  • Postmark gives you more teammates on lower-tier plans than SendGrid.

Customer experience

First, I must note that I’ve found concerning reviews for SendGrid on Trustpilot, where it has a staggering 1.1 out of 5 ranking. It’s mostly people giving it 1 stars with negative remarks on its customer support and account deletion, so be wary of that if you opt for SendGrid.

However, on other websites like G2 and Capterra, SendGrid has overall solid reviews, so I’m not sure if it’s an issue with Trustsend. For instance, people praise the platform’s API and how it helped them reduce bounce rates.

Other users remark that SendGrid’s SMTP is easy to set up and that they’re achieving high deliverability rates.

Amazon SES

G2: 4.3 🌟 Capterra: 4.7 🌟

Amazon SES (Simple Email Service), is a cloud-based email service provider for experienced developer teams who are already in the AWS (Amazon Web Services) ecosystem.

Notable features:

  • Amazon infrastructure

Being a part of the AWS ecosystem, Amazon SES has a rock-solid infrastructure based on cloud-native architecture. All the technical jibber-jabber aside, this means you don’t have to worry about hiccups during email spikes, downtimes, or anything of the sort.

More importantly, Amazon SES scored quite well compared to Postmark on our deliverability tests:

  • CloudWatch and Virtual Deliverability Manager (VDM)

Although Amazon SES doesn’t offer native analytics for tracking important deliverability metrics, you can either integrate it with Amazon CloudWatch or use the Virtual Deliverability Manager (VDM).

This way, you get in-depth analysis of the performance of your emails, and you can even go as far as creating custom dashboards and notifications.

Source: Amazon SES

  • AWS integrations

Besides CloudWatch and VDM, you can also integrate SES with a plethora of other AWS integrations. This gives you plenty of room to customize your sending experience, but requires some technical expertise.

For instance, you can use Amazon SNS (Simple Notification Service) to trigger alerts when your recipient’s domain starts rejecting your messages for some reason. Or, you can route bounce or delivery notifications to take further action, like removing invalid addresses or recipients.

Some other useful AWS integrations include: Amazon S3, Lambda, and EventBridge.

How is Amazon SES different from Postmark?

The biggest difference between the two is that Postmark is an out-of-the-box solution requiring minimal setup for you to start sending emails with it. 

More specifically, with Postmark, you can just register, verify your domain, copy/paste the code snippet for your preferred language or framework, and start sending.

On the other hand, Amazon SES requires an initial setup and previous AWS knowledge for you to start sending. However, if you have experience, I’d say this is a benefit over Postmark, since SES gives you plenty of room for configuration. You can select IP pools, play around with suppression rules or event archiving, and the list goes on.

Security

Amazon SES is as secure as it gets since it offers native AWS controls like IAM policies, MFA, and extensive logging via CloudWatch and CloudTrail. It’s also highly customizable and supports both opportunistic and forced TLS with optional MTA-STS.

Compliance

The main difference between Amazon SES and Postmark compliance-wise is that the former supports HIPAA, whereas the latter doesn’t. Also, SES uses CloudTrail for logging.

Pros

  • Integration with AWS
  • Reputable IPs
  • Solid webhooks
  • Super affordable
  • Generous free plan
  • Inbound email support

Cons

  • A steep learning curve that requires you to be at least familiar with the AWS console. 
  • Expert deliverability support is only available at the enterprise-level AWS plan.

Pricing

Free plan: Amazon SES offers 62,000 emails for free if you’re using Amazon EC2 and AWS Elastic Beanstalk.

Amazon SES offers one of the most affordable SMTP/API services on the market, and the simplest one at that, too. Namely, you pay $0.10 per 1,000 emails. That’s it, that’s the whole philosophy behind it.

If you’re interested in more numbers, here’s how it fares against Postmark:

Price for Amazon SESPostmark
10,000 emails$1$15
50,000 emails$5$55
100,000 emails$10$100
250,000 emails$25$250
700,000 emails$70$455

Key pricing differences

  • To use Postmark, you need to pay at least $15/month for 10,000 emails. With Amazon SES, there is no minimum monthly spend.
  • Managed dedicated IPs at Amazon SES cost $15/month per account, whereas standard ones cost $24.95/month per IP, which is more than 3 times cheaper than Postmark.
  • You can also pay $24.95 per month for a Bring Your Own IP Address (BYOIP)

For more details, please consult the official Amazon SES pricing page.

Customer experience

As I had expected before digging into online SES reviews, users seem to love its pricing model and the low cost. Additionally, a lot of users are well aware of the steep learning curve.

Source: G2

On X, I’ve found a few users who were not satisfied with Postmark since its acquisition by Active Campaign, its increases in pricing, and issues with transactional email sending. In the threads, other users seem to recommend Amazon SES as a solid alternative.

Brevo

G2: 4.5 🌟 Capterra: 4.6 🌟

Brevo is a five-in-one platform for relationship marketing that, besides SMTP and email API services, also offers a rich email marketing suite. This makes it a solid choice for teams looking to send email campaigns on top of their user-triggered, transactional emails.

Notable features:

  • Newsletters

Looking to spice it up and launch newsletter campaigns on top of your transactional emails? If so, you can use Brevo’s free newsletter software that includes a drag-and-drop editor, 40+ newsletter templates, AI writing assistance, and real-time analysis of the campaign performance.

Speaking of newsletters, Brevo also offers a vast collection of email templates, good-looking ones at that, too.

  • Automations

If you want to automate your email marketing workflows, look no further than Brevo’s automation builder. It’s super simple to use, has everything you need in one place, and there are even templates you can use. I should also probably note that both the builder and the templates are available even for the free plan users.

  •  Integrations

From integrations with CRM platforms like Salesforce and HubSpot to CMS integrations with Webflow or Wix, Brevo has them all. Well, not all of them, slightly over 150 to be more precise. Nonetheless, if you’re looking to connect your app/project with a certain platform, check out Brevo’s app marketplace to see if it has the supporting integration.

How is Brevo different from Postmark?

The major difference between Brevo and Postmark is that the former is a full-featured email marketing platform, whereas the latter is a transactional messaging service focused on speedy delivery of user-triggered emails.

With Brevo, you can create automations, send SMS campaigns, create emails with a drag-and-drop editor, and, on top of all that, integrate its SMTP or API with your app/project.

Also, even though it’s more of an email marketing campaign than a transactional email provider, Brevo still offers extensive documentation and supports major programming languages. However, I have to note that Brevo doesn’t offer any pre-made code snippets for its SMTP.

Pricing

Free plan: 300 emails per day

Brevo has quite a generous pricing model, offering all users with more than 10,000 monthly email sends unlimited contacts, as long as they stay within their Fair use limit. The limit is as follows:

  • Starter plan: 100.000 emails and 500,000 contacts
  • Business plan: 1.000.000 emails and 2,000,000 contacts

It’s also important to note that if you exceed these limits, Brevo might enforce restrictions on your account or ask you to upgrade your plan. And here’s what the plans offer:

Key pricing differences:

  • One of the most noticeable differences is that to remove Brevo branding, you have to pay $10-12 per month.
  • Brevo also offers dedicated IPs as add-ons, but they’re more affordable than Postmarks, coming with the price of $251 per year, compared to Postmark’s $50/month.

Customer experience

When I was going through online Brevo reviews, I was happy to see that other people also recognized the platform as having solid templates, segmentation, and managing marketing and transactional emails.

There were also a bunch of positive remarks for Brevo’s customer support team, like this one, for example:
