About Mailchimp's Email Builders

Mailchimp has 2 email builders to help you create and design your emails: the new builder and the classic builder. Both share core functionality, though they differ slightly in look, use, and capability.

In this article, you’ll learn about the differences between Mailchimp’s new builder and classic builder, and find resources for both.

About the builders

When you create an email or email template with Mailchimp, you’ll design it with the new builder or the classic builder. Both builders provide everything you need to create beautiful marketing emails for your audience, including drag-and-drop content blocks in custom or pre-built templates.

The new builder is our updated designer with a refined interface that lets you undo/redo your edits to your draft. Integrate third-party platforms with the Apps content block to pull in content from those integrations, use the Content Optimizer for guidance on your marketing content, add a Survey content block to collect feedback from your customers, and much more. To learn how to use the new builder, check out Design an Email with the New Builder.

The classic builder is the only builder that can be used to custom code an email template or include an RSS feed in your email. To learn how to use the classic builder, check out Design an Email with the Classic Builder.
