Email domains by provider list: which domains Google, Microsoft, Yahoo and Apple use

How do I find which provider a domain belongs to?

1. 1Type a domain or a full address in the search box. If it is on the list you see its provider.
2. 2Use the Provider menu to show one provider's domains, such as every Microsoft domain.
3. 3Download the list as CSV, TXT or a JavaScript object that maps each domain to its provider.
4. 4To split a whole list by who hosts the mail, use the bulk email provider lookup.

What can’t this tool tell you?

• It lists personal mailbox domains for ten providers, not every provider.
• A company address hosted by Google or Microsoft is on the company's own domain and is not listed.
• It says who runs a domain, not whether a mailbox at it exists.
• Providers add and retire domains, so a new regional domain may be missing.

Common questions

What domains does Microsoft use for email?

outlook.com, hotmail.com, live.com and msn.com, with regional versions such as outlook.fr, hotmail.co.uk and live.de. They are all filtered under Microsoft (Outlook.com).

Is googlemail.com the same as gmail.com?

Yes. Google says googlemail.com is the same mailbox as gmail.com, so both are listed under Google.

Which domains does Yahoo use?

Its country domains such as yahoo.com, yahoo.co.uk and yahoo.fr, plus ymail.com and rocketmail.com. Yahoo Japan is not part of the list.

Are company domains on Google Workspace or Microsoft 365 included?

No. A company's own domain is not a Google or Microsoft domain even when they host the mail. The email provider lookup reads a domain's MX records to tell.

Does the list cover every provider?

No. It covers ten providers and the personal domains we filter on. Regional providers and internet-provider addresses are on the free email providers list.

Can I download the list?

Yes, as CSV, TXT or a JavaScript object. Downloads follow the Provider menu, so you can take one provider's domains.
