What are ACD email message and attachment size limits?

The maximum outgoing message size, including attachments: 10 MB per message (after base64 encoding).

  • Messages exceeding 10 MB, including attachments, will bounce back to the sender. Messages larger than 10 MB that you try to send from Genesys Cloud will yield an error. You can work around this limitation by including links to larger documents stored in Genesys Cloud Documents. For more information about sharing a file within Documents, see About Documents and Share a file.
