Both TempMailo and Guerrilla Mail are free temporary email services that let you
receive messages without giving out your real address. The practical difference is what
happens after a message arrives: TempMailo adds Save
Inbox and Restore Inbox and a reply-only Reply
Relay, so the right choice depends on whether you only need to read a code once or want to keep
and respond to messages.
Features and availability may change. Check each provider's official website
for current information.
What both services have in common
At the core, both are disposable inboxes. You get an address you did not have to register, you use
it to receive sign-up confirmations or verification codes, and you keep your primary inbox out of
marketing lists. If your only goal is to grab a one-time code and move on, either kind of
temp mail can do that.
Where TempMailo is different
These are TempMailo's own features, verifiable on this site:
- Save Inbox — protect a temporary inbox with a password so it is not lost when
you close the tab.
- Restore Inbox — bring a saved inbox back later using its email name, domain,
and password.
- Reply Relay — reply to the original sender of a message you received, without
exposing your personal email. It is reply-only and rate-limited.
- Browser extensions and an Android app — generate and read inboxes outside the
website.
- Multiple domains — pick from more than one address domain.
We are not going to list Guerrilla Mail's feature set here, because those details are controlled
by that provider and can change. If a specific capability matters to you, confirm it on their
official site rather than trusting a third-party comparison.
Who each service may suit
Neither tool is "better" in the abstract — they fit different needs:
- Choose a plain throwaway inbox if you want the simplest possible one-time
address from a name you already recognise, and you will never need the message again.
- Consider TempMailo if you might need to keep a message, come back to the same
inbox later, or send a single reply to whoever emailed you — for example a
verification code you want to re-read, or a
support auto-reply you need to answer.
Things to keep in mind with any temporary email
- Some websites detect and block disposable email domains at sign-up. A temporary address may be
rejected by certain platforms, and that behaviour is set by the receiving site, not by the temp
mail provider.
- Temporary inboxes are meant to be short-lived. Do not use them for anything you need permanent,
recoverable, or legally important access to.
- TempMailo's Reply Relay is deliberately limited (reply-only, 3 replies per inbox per day, a
15-minute cooldown, up to 2,000 characters, and up to 2 attachments) to keep it safe and free.
FAQ
Is TempMailo a Guerrilla Mail alternative?
TempMailo is another free temporary email service. It covers the same basic need — receiving mail without your real address — and adds Save Inbox, Restore Inbox, and a reply-only Reply Relay.
Can I keep a temporary inbox after closing the browser?
With TempMailo you can save an inbox with a password and restore it later using its name, domain, and password. Availability of a similar feature on other services varies — check their official site.
Can I reply to a message from a temporary inbox?
TempMailo lets you reply to the original sender through Reply Relay. It is reply-only, so you cannot start a new message to a stranger, and daily limits apply.
Will a temporary email always be accepted at sign-up?
No. Some services block disposable email domains. Whether an address is accepted is decided by the site you are signing up to, not by the temp mail provider.
Are these services free?
TempMailo is free to use with no registration. Pricing and limits for other providers may change, so confirm current details on their websites.
Which one should I use?
If you only need a one-time code, either works. If you may need to keep, restore, or reply to a message, TempMailo's extra features are worth considering.
