10 Minute Mail alternative: GrabMail vs 10minutemail

At a glance

Fourteen rows. Every 10 Minute Mail cell is what its home page, FAQ, security and about pages said on 2 September 2026; every GrabMail cell is read from the constants the service enforces. “Partly” means a caveat the row cannot hold — the sections below say which.

Checked 2 September 2026. 10 Minute Mail publishes no API, no domain count, no attachment policy and no rate limits, and the cells say “not published” rather than guess. It is free with donations; there is no paid tier to price.

What 10 Minute Mail does well

There is a reason the name became a generic term. Four things 10 Minute Mail does that GrabMail does not:

• The inbox is yours alone. The address is unique and nobody else can open it — no password, no account, just an address nobody can guess. GrabMail’s public mailboxes are the opposite by design, and the alias is the workaround.
• Nothing touches a disk. Its security page says all data lives in memory, is never written to storage, and has no retention period beyond the session. That is a stronger privacy claim than GrabMail makes: here mail sits on a disk for 5 days.
• It replies. Some sites require an answer to a message before they let you in; 10 Minute Mail lets you reply and forward from the page. GrabMail is receive-only, by design, and cannot.
• It is simpler than anything. One page, one address, one timer, since November 2006, in 47 languages. There is no setting to get wrong.

Where GrabMail is different

GrabMail is built for the case a ten-minute inbox cannot serve: mail that has to be there later, addresses you chose, and readers that are not people.

• 5 days. A trial that emails on day three, a receipt you want tomorrow, a code you read after a meeting — all gone at 10 Minute Mail, all still here. Retention is enforced by a job, not by a countdown you have to keep clicking.
• Any address, on 8 domains or your own. Type trial@grabmail.io and it exists; point a domain at smtp.grabmail.io and every address on it exists. 10 Minute Mail assigns you one address and offers no domain of your own.
• An API and an MCP server. A test suite polls /api/v1/mailbox with no key; an agent opens an inbox over MCP and waits up to 25 seconds for a message. 10 Minute Mail has neither and never claimed to.
• No ads. 10 Minute Mail runs display advertising to stay free. GrabMail runs none, has no analytics and no third-party script, and stays free by selling an off-blocklist domain pool to developers.

Price, side by side

There is little to compare: 10 Minute Mail is free, funded by ads and a published donation address, and sells nothing. GrabMail’s only paid plan buys access to a pool of domains kept off the disposable-mail blocklists; everything in the table above stays free.

For developers: reading a mailbox

10 Minute Mail publishes no API, so this section is one-sided. The command below reads a GrabMail mailbox with no header, no key and no account:

$ curl -sG https://grabmail.io/api/v1/mailbox --data-urlencode "address=anything@grabmail.io" | jq '{count, alias}'

A 200 with count: 0 and an alias is the whole proof. The reference is three endpoints — list a mailbox, read a message, delete it — and the Python and Node.js guides show a wait loop with a deadline for a test that expects a code.

If you have been driving 10 Minute Mail with a browser automation to make it act as an API, stop: it is against the grain of a page built for a person, and a keyless GET does the same job in one line.

For AI agents

An agent cannot use 10 Minute Mail without steering a browser, reading a countdown and hoping the tab survives. GrabMail’s server at https://grabmail.io/mcp gives it an inbox with no key: create_inbox, a blocking wait_for_message of up to 25 seconds, read_message.

Email for AI agents covers the four-call loop and the guard rails; the client guide has the configuration for Claude, Cursor and five others.

Switching from 10 Minute Mail

There is nothing to migrate — that is the point of a ten-minute inbox — so the switch is a habit:

1. Type a name instead of copying one. On the front page, choose any local part on grabmail.io, mixozia.com or another of the 8 public domains. It is an inbox from the first message and stays one; there is no timer to extend.
2. Hand out the alias, not the address. Every GrabMail mailbox has an alias that delivers to it and cannot be used to open it. Give the alias to the form; keep the address. That is how a public mailbox gets most of the privacy 10 Minute Mail gives you for free.
3. Delete when you are done, if you want to. A message can be deleted from the inbox or the API at once; otherwise it goes after 5 days. If you liked that 10 Minute Mail forgot you automatically, this is the button to press.
4. Keep 10 Minute Mail for the one-offs. There is no reason to have only one throwaway habit. A private ten-minute address for a download gate; a chosen five-day address for a trial.

Which one, for what

The honest split is by how long the mail has to live and who reads it:

When to stay with 10 Minute Mail

Three situations where switching would cost you something real:

• Privacy is the whole reason. A unique address only you can open, held in memory, gone in ten minutes: that is a better privacy story than a public mailbox on a disk for 5 days, and no alias changes it.
• You need to reply. GrabMail cannot send a single message, to anyone, ever. If the form wants an answer by mail, 10 Minute Mail can give one.
• You like the countdown. Forgetting is a feature. If you would rather never see the inbox again than have to delete it, the timer is doing you a service.
