From February 1st, 2025, it is mandatory for your custom domains in Social to be DKIM verified if you want to send emails to anyone outside your Social portal. If not verified, the default email address (notifications@zohosocial.com) will be used for sending all emails from Social.

If your custom domain is already verified in any other Zoho product, you can just add it in Zoho Social and start using it. 

 To add custom email domain  

This setting is accessible and can be done only by the Zoho Social portal admin.

1. Go to Settings.
   
2. Under General Settings, click Portal Settings and navigate to the Email Authentication tab.
   
3. Click Add a domain.
   
4. Enter your custom domain name and click Add.
   

The domain name you're trying to add should be the same as the domain name in which the email addresses of any of your portal admins are hosted.
