Yeah, I have to agree that the ‘send as’ can be a pain, would be nice if it sent as the recipient email by default. As far as people spamming looking for a legit address, I’ve fortunately not run into that, but I could see how that could happen.

I went with Pro for the custom domains and catch-all inbox. Now I can give out whateveriwant@mydomain.com and it will get back to me. It’s nice for easily identifying phishing, plus you can set up filters to trash emails to a particular address automatically, so if one of your addresses gets compromised you can just filter them out. Also, it’s nice to see who’s selling your info!
