Emails sent from our servers are capped at a 50 MB size limit. This encompasses the entire email: the body, attachments, and headers.
How Big Can Your Attachments Be?
Due to the encoding necessary for email attachments, the maximum file size you can attach is roughly 37 MB. This ensures your email stays within the 50 MB total size limit.
If the Email Size Limit is 50 MB, Why Can I Only Attach About 37 MB?
Attachments need to be converted into a format compatible with email systems, which is done through Base64 encoding. This encoding process increases the size of your attachments by about 33%. For instance, a 3 MB file will take up approximately 4 MB of your email's size limit after encoding. Considering the space needed for your email's text and other components, the largest attachment you can include rounds out to about 37 MB.
Sending to Other Email Services
Remember, while we support emails up to 50 MB, the recipients' email services might have tighter restrictions and could reject larger emails. To avoid any issues:
- Keep emails and their attachments below the 50 MB limit when possible.
- Use file-sharing services for very large files and share the link via email.
- Check the recipient's email service for any size limitations if you're sending large attachments.
