Burner Mail vs Guerrilla Mail (2026): which should you pick?

Pick Burner Mail if

• Fits if you want a different forwarding address for each sign-up
• Works for people who want to cut off one sender without changing their real address

Look elsewhere if

• Skip it if you want to try it free, as new users must pay before creating burners
• Skip it if you want to see prices first, as none are shown publicly
• Not for you if you want open source, as the code is private
• Watch out: the vendor doesn't recommend sending passwords or card numbers through it
• Watch out: payments go through a reseller under its own terms

Pick Guerrilla Mail if

• Fits if you need an address for a one-off confirmation link
• Works for developers who want a free inbox to test sign-ups against

Look elsewhere if

• Not for you if you need mail kept, as everything is deleted after 1 hour
• Skip it for anything private, since anyone with the inbox ID can open it
• Skip it if you dislike ads, as the site shows them and uses Google Analytics and AdSense
• Watch out: there's no spam folder

Burner Mail

• Pricing is not shown on the public site; plans are chosen after creating an account, so no price is recorded here.
• The vendor removed its public free plan, so new users must pay before creating burners, while existing free accounts keep their current limits.
• The source code is private, and the vendor says it does not recommend sending sensitive data such as passwords or card numbers through the service.
• Payments are handled by an online reseller and merchant of record under its own terms.

Guerrilla Mail

• Anyone who knows an inbox ID can open that inbox, so it suits low-stakes messages only.
• Everything is deleted after an hour, and there is no spam folder.
• The site shows ads and uses Google Analytics and AdSense cookies, per its About page.
• The open-source part is the Go-Guerrilla mail server; the vendor does not say the whole website is open.

Burner Mail

One-click burner addresses

The Chrome and Firefox extension adds an icon to email fields and generates a new address for that site.

Block, disable or delete

Any burner can be turned off or deleted from the web app or the extension if a sender turns abusive or sells your address.

Replies from a burner address

Replies pass through the vendor's servers so the recipient sees the burner address, not your personal one.

Spam quarantine

Suspected spam is held for review and deleted after 14 days if you do not release it; the FAQ says quarantine is on every plan.

Multiple recipients and custom domains

A burner can forward to several inboxes, and burners can be recreated on verified private domains.

Guerrilla Mail

No registration

A random address is created when you open the site, and you can also choose your own address.

Scrambled address

Anyone who knows an inbox ID can read that inbox, so the site offers a scrambled alias as an extra layer of protection.

Compose and reply

The inbox has a compose window, so you can send from the disposable address.

One-hour retention

Messages are deleted an hour after they reach an inbox, or sooner if you delete them.

API

A public API is documented, and the vendor says its own front end uses it for everything.
