Allow HTML + Image Zip Uploads for Emails (Like Mailchimp)

Status: Idea Submitted

HubSpot needs a true drag-and-drop HTML email import function, like Mailchimp’s .zip upload feature, for users who work with custom email templates. This feature would allow users to upload a .zip file containing an HTML file and associated images, and have the email auto-populated with correct image paths, structure, and styling, no manual reformatting needed.

This would dramatically streamline the process for marketers and designers, especially smaller teams and users managing frequent sponsored or external partner emails. Right now, I spend excessive time (often with AI help) trying to reformat perfectly valid HTML just to make it work in HubSpot. Even when following HubSpot’s rules, I constantly run into issues with nesting, inlining styles, and image hosting.

I’ve tried creating a reusable template, but even that’s frustrating. Our footer never renders correctly, and maintaining formatting consistency is difficult. A proper zip upload would save hours and improve reliability. Mailchimp does this effortlessly. HubSpot should too.

This feature would benefit:

  • Marketing teams managing external content/sponsored emails
  • Users transitioning from design files or other email platforms
  • Anyone needing full control over their email layout while still using HubSpot’s tools
