Contact [ServiceTitan Technical Support](http://go.servicetitan.com/ask) to check if the employee's email is on the bounce list. 2. Ask support to remove the email address from the bounce list. 3. Go to your email server settings. 4. Add ServiceTitan's domain to your email whitelist. 5. Follow your [email provider's instructions to whitelist domains](https://clean.email/blog/email-security/how-to-whitelist-an-email). 6. Test sending the activation email again in Enterprise Hub.
