The only problem I have experienced few times with those unique email addresses is, sometimes they/utilities ask me to email from my official email address, and my setup is a catch-all, so I have to log in my pc at home, set up that address, send email.

That's a problem of your provider needing you to have received email at a particular address (or else doing whatever you do on the PC at home) before you can send from it; not something inherent in unique addresses.

I just type in whatever address I want to send from, and then as long as the domain is verified in SES it'll go through.
