MAGY Domains List: 2025 Update

In light of Microsoft’s recent release of updated email sender requirements, I thought it would be handy to share an updated list of all of the consumer domains under the “MAGY” umbrella.

My personal definition of MAGY includes:

• Microsoft (Outlook.com/Hotmail/etc.)
• Apple (iCloud Mail)
• Google (Gmail, with their two domains)
• Yahoo (Yahoo Mail, AOL, Verizon, etc.)

And now, as of Microsoft’s most recent updates, all four of these very large consumer mailbox providers have similar sender requirements, which I document in more detail here.

Here are some things to keep in mind.

• These are CONSUMER mailbox domains only. The primary domains where free webmail access is provided for each provider. This does not include B2B, corporate or enterprise email domain mailbox hosting.
• Some entries are found based on MX record or MX domain matches and could be slightly inaccurate, but this should still be good enough for domain segmentation and MTA configuration purposes.
• Apple's private relay domain is not included, it is "privaterelay.appleid.com" and utilizes a separate MX. The Private Relay mail service is part of Apple’s “Hide My Email” functionality and you can learn more about that here.
• Google has two consumer webmail domains – the second one, googlemail.com, was initially utilized due to legal issues in Germany and the UK. They do not have other localized domains around the world for email, even though they own many alternate domains.
• Yahoo domains include AOL, Cox.net, and Verizon.net. The Yahoo list does not include AT&T domains, because they have a different inbound MX (mail) server, even though the mail is accessed by users using the Yahoo Mail webmail system.
