For my main email, I use a forwarding service address, which is the email address I give to people.  And the underlying actual email address I like to keep hidden as much as possible.  So in my reply-to field, I have the forwarding address shown.  How do I have my forwarding address shown in my "From" field in emails I send out?  I looked at the emails I'm sending, and it's putting my actual address there instead of the forwarding address.
