Email Builder and Template Library
Mailchimp's drag-and-drop email editor is one of the most refined on the market. You pick a template (or start from scratch), then drag in content blocks — text, images, buttons, social links, product listings, dividers. The templates are mobile-responsive by default and cover newsletters, announcements, product launches, and transactional formats. On Standard and above, you can upload custom HTML for full design control. The limitation for creators: the editor is optimized for marketing emails, not long-form writing. If your newsletter is primarily written content (think Substack-style essays), the block-based editor feels heavy compared to the simple text editors in Beehiiv or Substack. You are designing an email, not writing an article — and that distinction shapes the experience.
