Who runs mail.com

According to its about page, mail.com was founded in 1995 as Vanity Mail Services and bought by the German United Internet group in 2010. United Internet AG owns it today; the service is run by 1&1 Mail & Media Inc. in Philadelphia, the company named in the site’s footer. The mail.com name itself was first registered on March 24, 1997.

Mail for the domain goes to mx00.mail.com and mx01.mail.com, the provider’s own servers.

Can you still create a mail.com address?

Yes. The mail.com home page offers free email and lets new users “choose from 100+ email domains”. @mail.com is one of them. Among the others the site names are @email.com, @usa.com, @dr.com and @myself.com. That explains addresses you may not recognize: jane@usa.com or jane@dr.com is a mail.com account, not a fake company address. The email.com profile looks at one of them in detail.

Is mail.com a valid email domain for your list?

Yes, treat it like any other webmail address:

Real domain, not an example. The second-level names reserved for examples are example.com, example.net and example.org (RFC 2606). Because mail.com is real, a made-up name there is not a harmless placeholder: it belongs to a stranger or to nobody, so check the address, not just the domain.
Free provider. mail.com and the other mail.com domains we checked (email.com, usa.com, dr.com, myself.com) are on our free email domains list. If your form only accepts work addresses, these count as personal.
Not disposable. These are regular accounts, not throwaway inboxes.

To check whether a given mail.com address has a mailbox behind it, use is this a real email address. The guide on how to check if an email exists explains what that check can and can’t tell you. For mail-app setup, see the mail.com IMAP and SMTP settings.
