Share Files with Contacts

Mailchimp offers free file hosting so you can add a file to an email campaign and share it with your contacts. You can upload and share many types of files including images, documents, spreadsheets, audio, or video.

In this article, you'll learn how to upload a file to an email campaign and share it with your contacts.

Before You Start

  • We offer file hosting instead of traditional email attachments because attachments can slow or stop bulk email delivery, or cause security software to completely block your email.
  • File hosting does not support zip files containing unsupported file types.

File Guidelines

You can upload many types of files to your Mailchimp account, and share them with your contacts. Each image file should be approximately 1MB or less, and other file types should be 10MB or less.

Here are the file types we allow in Mailchimp.
