Announcing New Rules of Practice to Implement Catalyst Mail

This announcement is to bring to your attention that with effect from Feb 1st, 2026, to send emails using the Catalyst Mail component the following prerequisites need to be satisfied.

1. You will need to verify your sender email address.
2. You will need to verify your domain.

This change is being mandated to ensure that the emails sent using the Mail component are completely secure.

If you attempt to send an email without verifying your domain, an exception will be thrown, and the email will not be sent.
