Often, when an email is generated out of ClickClaims CMS, but is not received by the recipient, the cause is due to an email provider blocking emails or marking them as spam.  

If the emails are being delivered to the recipient's junk folder instead of their inbox, they should mark the sender's email and/or domain as not spam so future emails are properly delivered and not blocked.

In some instances, the user or their IT department may need to whitelist the following IP Addresses that are used by the ClickClaims CMS application: 

69.63.159.101

69.63.149.165

69.63.132.124

69.63.133.254

If CMS is not sending out emails, you can find a troubleshooting article to help you configure the system emails here.
