Are there any email sending limits?

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.

There are two possible limits Mailfence accounts can reach. Following are those limits depending on the type of subscription you take, typically:

Free email sending limits:

  • Max Web Mail Hourly Rate = 50
  • Max Web Mail Peak Rate = 10 (Max recipients per mail)
  • Max SMTP Relay Hourly Rate = 0 (No SMTP service)
  • Max SMTP Relay Peak Rate = 0 (No SMTP service)

Entry email sending limits:

  • Max Web Mail Hourly Rate = 120
  • Max Web Mail Peak Rate = 60 (Max recipients per mail)
  • Max SMTP Relay Hourly Rate = 120 *
  • Max SMTP Relay Peak Rate = 60 * (Max recipients per mail)

Pro email sending limits:

  • Max Web Mail Hourly Rate = 120
  • Max Web Mail Peak Rate = 60 (Max recipients per mail)
  • Max SMTP Relay Hourly Rate = 240
  • Max SMTP Relay Peak Rate = 120 * (Max recipients per mail)

Ultra email sending limits:

  • Max Web Mail Hourly Rate = 240
  • Max Web Mail Peak Rate =  120 (Max recipients per mail)
  • Max SMTP Relay Hourly Rate = 480
  • Max SMTP Relay Peak Rate = 240 (Max recipients per mail)

* Subject to change

In addition to above email sending limits, our anti-spam/anti-abuse system can immediately block the sending of suspicious accounts. If you face such kind of blockage, and believe this was an error from our side, then send us an email to our support, preferable using your Mailfence account reset/notification address.

Please note: Mailfence is not designed for bulk/spam emailing.

Other points:

  • Sending Limits do not affect inbound mail.
  • Each of the inbound/outbound mail size is limited to 50MB.
