FAQ:

Why is the user signature blank when I send a manual email in the conversation tab?

If email signatures are not working, make sure that you are logged in as the user with the signature.

If you are logged in as an agency trying to send an email on behalf of the user, the user signature will not work.

However, the workaround is to send the email through the workflow/campaign instead of sending them manually. You can use the other methods listed here aside from the conversation manual way:
