Yes. Email sending limits help to protect Mailfence IP addresses reputation and ensure all messages sent from Mailfence are delivered in the recipient’s inbox, and not the spam folder.

* Note: In addition to the above email sending limits, our anti-spam/anti-abuse system further restricts the sending of emails based on dynamic factors (e.g., sending IP’s reputation and the recipient address domain’s sensitivity) and can immediately block the sending of suspicious account activity. If you encounter such a blockage and believe it to be an error on our part, then contact our support by email.

** Email attachment size increases (depending on the file type) to represent it in a format (MIME encoding) that email system understands.
