What is the size limit for attachments files sent via Mailjet?

File attachments is not possible when sending messages via our online newsletter tool. You must use the SMTP relay to send attachments. To learn more about using attachments, please go to: How can I add an attachment to a campaign.

File attachments are limited to 7MB per file, and your total email message size must not exceed 10.2MB. This size limitation applies to all our plans. Please keep in mind that sending attachments with mass mailings is not recommended as some ISPs will block messages beyond the size of 5MB.
