How can I use Gmail for all my domain email accounts?

Episode 1206 (53:09)

David from Salt Lake City, CA

David has several email addresses from multiple domains and wants to know if he can send emails from a master Gmail account and choose different email account options to send from. Leo says that's called "delegation," and he can find the account option in Gmail settings. He could also just change the 'reply to' in his email client.
