Craft Stunning HTML Emails: 5 Frameworks You Need In 2024

Besides various drag-and-drop email editors and custom HTML templates, there’s another powerful way to streamline and accelerate the email creation process: Email frameworks.

Think of them as a toolbox filled with essential building blocks: buttons, columns, spacers, and more. Forget endless lines of code – frameworks streamline the process, saving you time without sacrificing quality.

So, whether you’re a coding pro or a marketer seeking a simpler solution, this guide is for you. We’ll explore the top-rated frameworks and show you how to leverage them to build emails that resonate with your audience and conquer the inbox.

To ensure we’re all on the same page, let’s quickly look at HTML emails before diving into email frameworks.

Email Frameworks With And Without Custom Tags

HTML emails are created using Hypertext Markup Language (HTML), the same language that builds web pages. HTML serves as the building blocks of your email, defining the structure and organization of the content. Imagine placing text, headings, buttons, and images in your email—all of that is laid out with HTML.

But HTML on its own wouldn’t make your email look very exciting. That’s where CSS comes in! Cascading Style Sheets (CSS) dictate how the email elements are displayed. They control visual aspects like fonts, colors, backgrounds, and image layouts.

Enter email frameworks. 

Email frameworks are like pre-built toolkits for email developers. They offer a collection of ready-made HTML and CSS components that you can snap together to build emails quickly and efficiently.

You can use an email framework as a base to write your code. Frameworks provide structure, define rules, and offer the essential tools to create a project.

Here’s the breakdown of the two main framework types:

  • Frameworks with Custom Tags: These use a special coding language on top of HTML/CSS. This can be helpful for teams with strong coding skills who want to avoid writing a lot of HTML/CSS from scratch or who want to automate parts of the email-building process.
  • Frameworks without Custom Tags: These rely solely on clean HTML and CSS code. This approach offers more flexibility and is generally easier to learn for beginners.

Some tools even combine elements of both approaches, giving you more options.

With the foundation laid, let’s dive into the heart of the matter: the top five frameworks for building HTML emails in 2024.
