Email and Domain Restrictions

Modified on Tue, 8 Sep, 2020 at 9:04 AM

Email Domain Restrictions exist for restricting your system from sending emails to domains or email addresses that are not specified specifically. If you have Email Domain Restrictions in place you may receive the error shown below if you try to send to a domain or email that is not in the list.

Error sending email to 'xxx'. Email addressed (xxx) is not approved for sending

Review your Email Domain Restrictions by going to Settings --> SMTP Settings --> Email Domain Restrictions. If the setting is blank, there are no restrictions and emails can be sent to any email address. You can add one or more restrictions by adding them one per line. A line may contain either a single email address or a domain. The system using string matching and tests if the email you are trying to send matches one restricted domains. If it does, it will allow it. For example: will allow sending to and will allows sending to any email any Gmail user.

On-boarding Tip!

We recommend restricting emails to test user emails only during the initial on-boarding to allow for small batch email testing. This restricts mass emails until testing and on-boarding is complete. Only users involved in testing should be added, all other emails will be prevented from being sent. Upon successful configuration and go live status, this feature can then be modified to allow mass consumer emailing and prevent unwanted email blocking.
