1. ending an email to an incorrectly spelled or non-existent email address will result in the email not being delivered. While this might seem obvious, it’s a mistake that is often overlooked and occurs frequently.
2. Another method to check is by sending an email to yourself. This can be accomplished by creating a new communication.

Navigate to the Communication List and click on “New.”

3. If the above method doesn’t work, consider reconfiguring your email account.

Go to Email Account, open the email to check, and if everything appears to be correct, click on “Save.” If there are any configuration issues, an error will be displayed, allowing you to address them accordingly.

4. Review the email queues for any unsent messages or errors.

If the state shows an error (as shown in the screenshot below), you can identify the cause of the error by opening the email and scrolling down to the “Error” field.
