Appendix: 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.

Note

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