Overview

Front’s attachment size limits vary based on the channel type you’re using.


Size limits

Front's attachment size limits:

  • Gmail: 25 MB per message

  • Office 365*: 100 MB per message

  • Generic SMTP (Sendgrid): 19.5 MB per message

  • Custom SMTP: 25 MB per message. Attachments can be image files, PDFs, and documents.

Troubleshooting

I'm seeing an attachment limit warning without adding any new attachments

This can occur when replying to messages which contain attachment or inline images; each reply can repeat the existing attachments, increasing the total attachment size on the message.
To work around this, you can click the "..." icon in the bottom-left corner of your message in the composer to view the previous messages, then the "x" icon on the right to remove the previous messages from your reply
