It sounds like you’re looking for the signature settings which is found under each users profile from within the Agents section of the Admin settings. The other option is this may be configured under the email template settings for your “Agent Reply Template” with the following placeholder:

{{ticket.internal_agent.name}}

Hope this helps! 

Hi, 

You can check two things here, one is Admin → Email notifications - > Reply template. You can add the placeholder agent name and company name 

(OR)

at agent level, they can change the signature, you can do this from profile settings on top right corner

Thanks all. I did find it in the end but as we don't assign tickets to each other, the automation doesn't work. Not to worry. Thanks for help everyone.
