Testimonial of Fame, customer of Mailtrap

As a bootstrapped founder, you are the sales team, the HR department, and the ops manager all at once. The last thing you need is to become an email expert.

Mailtrap is the reliable platform that handles our email delivery with rapid sending times and high inboxing rates. This frees me up to focus on growing the business, not debugging email issues.

They even offer a discount for bootstrapped founders, so you can focus on building your business, not your email bill. It’s a key tool for our success.

We were really happy to switch off Mandrill. We’ve found Mailtrap more affordable, and the support from the team has been fantastic. Cutting over was really easy and email deliverability has been great.

Testimonial of web3 jobs, customer of Mailtrap

I switched from Postmark to @Mailtrap for sending ~1M emails per month for my SaaS. It’s cheaper and has a better stats design.

Also, team is very nice and helped me to improve open and bounce rates.

Frequently Asked Questions

  • What are Mailtrap SMTP rate limits?

    Mailtrap enforces a general rate limit of 150 requests per 10 seconds per API token. SMTP sending throughput depends on your plan tier and sending patterns. For optimal performance, distribute sends evenly rather than sending in bursts, and implement retry logic with exponential backoff if you encounter temporary failures. Detailed rate limits are documented in the Mailtrap docs.

  • How does Mailtrap handle bounces and suppression lists?

    Hard bounces are added to a global suppression list immediately and are not retried. Spam complaints received via feedback loops are suppressed across all streams automatically. You can view and manage suppressions directly in the dashboard or via the API.

  • Does Mailtrap SMTP support sending from multiple domains?

    Yes. You can add and verify multiple sending domains within a single account. Each domain requires independent DNS verification before sending. Unsubscribes are domain-specific, so a recipient unsubscribing from one domain does not affect sending from your other verified domains.

  • Can I use SMTP and the API on the same account?

    Yes. Both methods share the same sending infrastructure, IP pools, and deliverability setup. You can switch between them or use both simultaneously without any additional configuration.

  • How does migrating from another SMTP provider work?

    Mailtrap provides dedicated migration support including DNS transition guidance, IP warm-up planning, and deliverability monitoring during the switch. Step-by-step migration guides are available for SendGrid, Mailgun, Postmark, Amazon SES, Brevo, and Mailchimp Transactional.
