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. A limit of 5,000 messages per e-mail address per 24 hours is imposed. The following limits also apply: No more than 7,000 recipients per day. No more than 1,500 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. 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 5MB in size. This applies to all messages sent via the PHP mail() function. Autoresponders Emails An autoresponder only sends once every 10 hours per sender Zero Tolerance Spam Policy We take a zero tolerance stance against the sending of unsolicited email, bulk emailing and spam. Please refer to our Acceptable Use Policy for more information. Please note: If you do wish to send a larger number of e-mails than any of the limits mentioned above, we would recommend looking at a specialist marketing email platforms such as SendGrid, Mailgun, or Mailjet. New Mailbox Limit When a new mailbox has been set up, the sending is limited to 40 per day for 7 days. This is an abuse rule to prevent new mailboxes being set up and used immediately to send out high volumes of spam emails. To preserve the platforms reputation and protect mail being sent from being spoofed as spam by third parties this rule was put place to protect that status.
