What are ACD email message and attachment size limits?

ACD email messages and attachments are subject to size limitations. 

Keep the following notes in mind:

  • Genesys Cloud uses base64 to encode messages and attachments.
    • The maximum outgoing encoded message size, including attachments, is 40 MB. After the base64 encoding to the email body and file attachments, the net email size is about 29 MB.
    • You can send links to larger documents stored in Genesys Cloud Documents.
    • For more information about sharing a file from Documents, see About Documents and Share a file.
  • If your organization uses a custom SMTP server integration, Genesys Cloud adheres to the maximum allowable size that you set on your SMTP server--up to 40 MB. You must set this value when you configure your SMTP server in Genesys Cloud.

Keep the following notes in mind:

  • Genesys Cloud uses base64 to encode messages and attachments.
    • The maximum outgoing encoded message size, including attachments, is 40 MB.
    • Outgoing messages that exceed 40 MB including attachments return an error.
