500 Hourly Maximum Outgoing Email Limit
This policy is applicable on a per domain basis on all Shared and Reseller servers, meaning that each addon and subdomain gets its own separate 500 outgoing emails per hour limit. This also applies to mailing lists. If a user sends over 500 emails in any hour, the emails will fail and may bounce back with an undeliverable error.
Each Connecting IP is Limited to 30 POP Checks per Hour
Users who attempt to go over the 30 check limit will likely get a password error indicating that the login is incorrect. The login error will subside within an hour and the email check will automatically unlock. The best way to prevent this occurrence is to disable email settings that automatically send and receive or set the email check to a higher time interval, such as checking once every 10 minutes.
Mailing Lists Over 900 Email Addresses Only Allowed During Off Peak Times
Any mailing list containing over 900 email addresses is only allowed to be sent during off-peak hours to prevent high server loads. HostGator defines off peak times as all day Saturday and Sunday, and 1AM - 8AM Eastern Standard Time, Monday through Friday.
Any mailing list larger than 5,000 email addresses will require a VPS or Dedicated Server. This means that users cannot send 12,000 emails a day (500 emails an hour x 24 hour period) on our Shared or Reseller plans. Please note that dividing one large list into smaller lists to get below this limit is not allowed on Shared or Reseller hosting plans.
VPS Plan and Dedicated Server Mail Limitations
HostGator's Dedicated Server and VPS accounts can send and receive unlimited emails per hour, and do not apply to the same mail restrictions listed in the section above for the Shared and reseller plans.
Our VPS and Dedicated server plans require that our users use a double opt in list or a safelist. For more information, please see the following article:
