What are my email sending limits?

Email Account Limits

The following limits apply to all messages sent via authenticated SMTP. This will primarily be used for email sent via a mail client, but can also include mail sent via your website if configured to send via SMTP.

We impose a limit of 8,000 messages per e-mail address per 24 hours.

The following limits also apply:

  • No more than 10,000 recipients per day.
  • No more than 2,000 unique recipients per day.
  • A single email may not be sent to more than 100 individual addresses.

As an example, if you were to send 100 emails to 5 different e-mail addresses within a 24 hour period. We would count 100 messages, 500 total recipients and 5 unique recipients.

Web Server Limits

A limit of 500 messages per day is imposed on all e-mail sent by our web servers. E-mails sent by the web servers should be no larger than 5 MB in size. This applies to all messages sent via the PHP mail() function.

Email Size Limits

Our mail system accepts attachments up to 32MB in size, and the maximum message size in our network is 50MB.
