I hope this is the right forum.
Is there any benefit to keeping an e-mail address with a provider like Yahoo or Gmail, as opposed to only using one at your own domain? For example, if you have a you@yourdomain.com account, would there be any legitimate reason to keep your you@gmail.com account? I'd imagine an address we can access even if our website goes down would be handy, but that's the only reason I can see not to close our other accounts.
