Here is a list of best free temporary email websites and email alias services. Many websites ask for an email address just to download a file, read an article or try a service, and that address then receives newsletters and spam for years. A temporary (disposable) email gives you a throwaway inbox for a few minutes or hours. An email alias is a longer-lasting forwarding address that you can switch off whenever it starts receiving spam.

Which one should you use?

  • Temporary email is for one-off sign-ups where you only need a confirmation link or code. Never use it for accounts you care about: once the inbox is gone, you cannot reset your password.
  • Email aliases are for accounts you want to keep but don’t fully trust. Mail is forwarded to your real inbox, and you can disable one alias without affecting the others.

Also note that many services now block well-known disposable email domains.

Top Pick:

Temp Mail is the quickest disposable inbox. For anything you may need again, use a free alias from SimpleLogin or addy.io.

Need a Permanent Address?

Temporary inboxes and aliases protect your real address, but for a business, a portfolio or anything you put on a business card, an address on your own domain (like [email protected]) looks more trustworthy and stays yours even if you change email providers.

There are two cheap ways to get one:

  • Forwarding only: if your domain uses Cloudflare, its free Email Routing forwards mail sent to your domain to your existing inbox. Sending from that address takes extra setup.
  • Real mailboxes: most web hosting plans include email accounts. Hostinger’s Premium hosting plan, for example, includes a free domain and 2 mailboxes per website for the first year, alongside hosting for your website. See Hostinger plans.

Final Thoughts:

Use Temp Mail or Guerrilla Mail when you just need a code and never want to hear from a site again. For accounts you plan to keep, set up SimpleLogin or addy.io once and give every website its own alias, so you always know who leaked or sold your address.
