Mailchimp has 2 email builders to help you create and design your emails: the classic builder and the new 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 classic and new 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 classic builder or the new builder. Both builders provide everything you need to create beautiful marketing for your audience, including drag-and-drop content blocks in custom or pre-built templates. For more resources on both email builders, check out these articles.
While both builders are available to design your emails, there are some differences to consider. Let's start with the classic builder, which is our traditional builder. This is the only one that can be used if you custom code an email template or include an RSS feed into your email. To learn how to use the classic builder, check out Design an Email with the Classic Builder.
Next is the new builder, a beta feature that has been updated with a refined interface. It’s the only builder 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, or add a Survey content block to collect feedback from your customers. To learn how to use the new builder, check out Design an Email with the New Builder.
Your default builder can be switched at any time. After you create a template or regular email, you'll access it in the version of the builder you used, even if you switch your default builder.
Content block types
Content blocks are what you use to build and design your email marketing. While many content block types are available in both builders,there are some content blocks that are exclusive to one or the other.
These are the content block types available in each builder.
