I too do it, although occasionally an hickup occurs. Last week, I signed up for something, and their system was unable to send an account activation email at theirCompanyName@myDomain.com I spent about 30 minutes with customer service on chat, and they were like, no, it's impossible to have them@my domain email. If I have, I should send them an email. I did it, sent email, and they were still not believing it.
