Unsupported attachment types - Amazon Simple Email Service Classic

This is the user guide for Amazon SES Classic. Updates and new features are only being documented in the new Amazon SES Developer Guide which we recommend to use.

Unsupported attachment types

You can send messages with attachments through Amazon SES by using the Multipurpose Internet Mail Extensions (MIME) standard. Amazon SES accepts all file attachment types except for attachments with the file extensions in the following list.


Some ISPs have further restrictions (such as restrictions regarding archived attachments), so we recommend testing your email sending through major ISPs before you send your production email.
