The Best Temp Email and Email Alias Providers Compared 8 min read · Written by Mae R Davis · Updated Sep 24, 2026 · Inbox Zero.

Temp email and email alias services solve the same problem, spam and tracking, in different ways. Public services like Mailinator give you an anonymous inbox you check online. Alias services like Email Monster, SimpleLogin, and addy.io forward mail to your real inbox under a name you invented. Here is how nine real providers compare, honestly.

Disclosure: Email Monster publishes this page and is one of the providers compared below. Its row uses the same publicly listed numbers as every other entry, and it is listed alphabetically within its category, not ranked first.

What is the difference between temp email and email aliasing?

A temporary email address is a disposable inbox you use once and abandon, usually on a public, shared domain. An email alias is a longer lived forwarding address, on a domain tied to your account, that hides your real address while still delivering mail to it. Some providers below do one, some do the other, and none do both.

Which providers use a public disposable inbox?

These give you an address instantly, with no signup, on a domain anyone could also be using. You read the mail on their website, not your own inbox.

• Guerrilla Mail issues an address immediately with no signup. The base service is free; a custom domain option costs $9.99 a year.
• Mailinator gives free public addresses at mailinator.com that anyone can read if they guess the name. Private, non public domains are a paid business feature starting at $79 a month.
• TempM works the same way: a free, public, no signup address on a shared domain.
• YOPmail also offers a free, public address with no signup required.

Which providers forward to your real inbox instead?

These ask for a signup once, then give you an address, or unlimited addresses, that forward mail to an inbox you already use.

• addy.io's free plan gives unlimited standard aliases with a 10MB monthly bandwidth limit and one recipient address. Paid plans start at $3 a month billed yearly for unlimited bandwidth.
• DuckDuckGo Email Protection gives unlimited free @duck.com addresses and strips trackers before forwarding. DuckDuckGo has reported that about 85% of emails sent to its addresses contained hidden trackers.
• Email Monster gives unlimited aliases on your own private subdomain. The free plan forwards up to 40 emails a month; Premium is $6.99 a year, or $2.99 a month, with no cap.
• Firefox Relay's free plan includes 5 email masks, with a paid plan for unlimited masks.
• SimpleLogin's free plan includes 10 aliases with unlimited bandwidth. Premium is $36 a year, or $4 a month billed monthly, for unlimited aliases and custom domains.

How do they compare side by side?

How Email Monster fits

Email Monster sits in the alias forwarding group: unlimited aliases on your own private subdomain, mail delivered to your real inbox, and no need to check a second website. The free plan covers 40 emails a month, and Premium removes that cap for $6.99 a year. For a truly anonymous, one time address you never intend to see again, a public disposable inbox like Mailinator or Guerrilla Mail is still the more direct tool.
