Outbound Email Limits
The total email size limit is 15 MB for outbound emails. This limit covers both the email content and all attachments. The limit leaves space for things like email headers and message encoding. Therefore, after NetSuite processes the email, the final message might be larger than 15 MB
Attachment size limits can vary depending on what you send. The table below shows the size limits for email messages and each attachment sent from NetSuite.
