How do you usually choose a new tool to use? Intuition? Friend’s recommendation? We prefer to make decisions based on data, so we’ve prepared this research for you. Whether you are a developer or a marketer, It will help you to define:

  • what kind of email builder you need: drag and drop one, HTML email generator, or even an email framework
  • how to choose the one that fits your needs from hundreds of email builder options.

Types of email builders

When you just start working with the email functionality, you should understand what you actually need first. For sure, you need to create a responsive email template to be rendered well on different devices in various email clients. You would like it to have a user-friendly interface and to be easy to use, offer reasonable pricing, and, probably, several extra features like an illustrations library. Before you start comparing different tools, answer a couple of questions below.

  1. Do you need to edit the email code? Even if you are a marketer who prefers a drag and drop builder and your answer is “never”, you might still need it. It is useful for developers in your team who work with creating user notifications or custom improvements, which should be exported/imported to/from another system.
  2. Do you use an email sending platform like Sendgrid or Mailchimp? If yes, then it might be reasonable to start with their built-in email editors.
  3. How often do you create new email templates? Daily, weekly, monthly, or a couple of times per year? Your reply should correlate with the pricing options the tool has. It makes sense to pay more for something you and your team use daily, for example.  

When searching for an HTML email builder, you will find four main types of options. 

HTML email generators. This type of tool is designed mostly for developers who are building the email functionality and need to create simple solutions without too much effort. They help to convert your input to the correct HTML (or sometimes another) format and compile it for further usage as a template. The result then can be imported to the email sending system or pasted to your app source code. HTML email generators are similar to the template engines. 

Responsive email frameworks. Email framework is the best option for developers. Usually, it is a markup-based language where your code is later converted to a responsive HTML. Email frameworks offer pre-built options and various components to streamline email coding. 

Built-in email templates. The vast majority of the email sending systems have their built-in email template builders. In most cases, they provide decent functionality for designing tailored templates. Also, they can support the import of custom templates or writing your HTML from scratch. If you need advanced features, you can use a third-party email building tool, and then import the result to your email sending system. However, it would be pretty weird to create a template in one ESP (email sending provider) and send it with another. 

Independent HTML email builders. This category of tools offers wide functionality for creating custom and pre-defined templates for both developers and marketers. They provide drag and drop email builders, HTML email editors, image libraries, and usually can be integrated with the most popular ESPs and CRM systems. 

Drag and drop editor doesn’t require any additional skills: you work with pre-designed blocks to add images and edit texts like in a usual document. In most cases, you can switch to a source HTML code to edit it if you need to customize the design.  In this post, we will focus on this type of apps and will highlight the most efficient options.

Overview of HTML email builders

From the hundreds of options, it’s impossible to choose one which suits every user. That’s why we checked and compared ten responsive email builders, which truly deserve your attention. Here is what we were considering:

  • suitability to both developers’ and marketers’ needs
  • friendly UI
  • availability of free options or trials and pricing/features ratio
  • additional options (like photo editor, libraries, etc.)
  • compatibility and integrations. 

Let’s go by a list of tools one by one with a comparison table in the end.

Cloud-based email builders

Chamaileon is based on EDMdesigner and in fact, is its rebuilt and improved version. 

Chamaileon can also be used for free. You just need to set up your account and choose if you want to build your email from scratch, from a pre-designed template, or import your already prepared HTML code.
