Disposable email
Mail.tm
Mail.tm keeps the mailbox available until deletion, but incoming messages have a shorter retention period: the FAQ says they are stored for 7 days. The service page promotes an “unlimited”* number of disposable addresses at no cost, while the API documentation describes free access with no paid tiers.
That distinction matters for anyone who needs to retain messages, rather than only receive them temporarily.

Addresses and Messages Have Separate Terms
The vendor’s homepage and FAQ, checked 2026-10-31, describe address creation, mailbox validity, and message handling.
- Address creation: automatically created temporary addresses without registration or personal details (homepage, checked 2026-10-31).
- Use: receiving messages and account activation codes (homepage, checked 2026-10-31).
- Mailbox validity: remains until the user deletes it (FAQ, checked 2026-10-31).
- Message storage: incoming messages are stored for 7 days (FAQ, checked 2026-10-31).
- Sending: the service does not provide email sending (FAQ, checked 2026-10-31).
Free Access Has No Paid Tier
The API documentation states that API access is free, with no paid tiers.
The two statements concern different parts of the service: the homepage describes address creation, while the documentation addresses API access. For a buyer evaluating a workflow, the practical distinction is whether the requirement is disposable addresses, API access, or both.
The Inbox Shows Sender and Message Text
In the browser mailbox, received emails appear below the address with the sender, subject, and message text, according to the FAQ. The vendor says the service runs in a browser on any device and can be added to a browser home screen.
The vendor describes the service as intended for sign-ups on untrusted sites, anonymous conversations, forums, and giveaways. It also says the addresses can receive account activation codes. These are descriptions of intended use, not a substitute for checking the rules of the site where an address is used.
Mailbox Deletion Removes Its Contents
Mailbox validity and message retention are separate conditions: the FAQ says a mailbox remains valid until deletion, while incoming messages are stored for 7 days. Deleting the mailbox erases both its address and emails, according to the FAQ.
The vendor says each mailbox has a unique, automatically generated password. Its FAQ adds that passwords are generated in the browser, stored encrypted, and cannot be reset by the service. Readers who need to recover access should clarify the password process before relying on a mailbox for anything they must keep.
REST and SSE Carry API Messages
The documentation describes Mail.tm as a temporary email API for creating disposable accounts and receiving messages through REST. It says the API follows OpenAPI v3 and requires no API key or signup to start.
The API provides available domain names; messages can be fetched through the API or received in real time using SSE. The documentation sets a general quota of 8 queries per second per IP address.
That quota is a practical constraint for API-based mailbox handling: clients need to account for requests per IP, not treat the interface as unrestricted. The documentation also describes bulk registration of disposable mailboxes for power users.
Free Access Covers Browser and API Use
The API documentation states that access is free and has no paid tiers. It also says users can start without an API key or signup, reducing the initial access requirements described in the docs.
Messages can be fetched through the API or received in real time using SSE, and the API provides available domain names. For browser use, the vendor says the service runs on any device and can be added to a browser home screen. These documented paths give readers distinct ways to access incoming mail without changing the stated receiving-only scope.
Receiving Only Limits Mailbox Use
The FAQ and API documentation set boundaries on message delivery, recovery, request volume, and reuse of the interface.
- The FAQ says incoming messages are stored for 7 days, while a mailbox remains valid until deletion.
- The service does not provide email sending, so it is limited to receiving mail.
- The vendor says the service cannot reset mailbox passwords.
- The API documentation sets a general quota of 8 queries per second per IP address.
- The documentation prohibits paid products that only wrap the API, and mirroring or proxying it under another domain.
- API users must link back to mail.tm somewhere visible, according to the documentation.
- The documentation prohibits using the API for illegal activity.
Several details are missing; they are listed under What we could not confirm.
Temporary Receiving Defines the Fit
Mail.tm’s documented scope fits workflows that need temporary inboxes for receiving messages, including account activation codes. The vendor also describes anonymous conversations, forums, and giveaways as intended uses.
For API-based handling, the documentation describes message retrieval through the API or real-time delivery using SSE. This is a receiving workflow, not a two-way email service, and the stated message-retention period should suit the task.
Compare Inboxes by Retention and Sending
In general, compare disposable-email services by mailbox lifetime, message retention, and whether sending is supported. Also check API access, per-user limits, paid plans, available domains, and the provider’s privacy statements before choosing a service.

Questions About Mailbox and API Terms
Does mailbox deletion happen when messages expire?
No. The FAQ says the mailbox remains valid until the user deletes it. Incoming messages are stored for 7 days, according to the FAQ. Deleting the mailbox removes both the address and its emails, according to the FAQ.
Can Mail.tm send email?
No. The FAQ states that the service does not provide email sending. Mail.tm is therefore described as a receiving service; the vendor says it can receive messages and account activation codes.
Can the service reset a mailbox password?
No. The vendor says mailbox passwords are generated in the browser, stored encrypted, and cannot be reset by the service. Each temporary mailbox also has a unique, automatically generated password, according to the vendor.
Can API users start without an API key?
Yes. The documentation says users can start without an API key or signup. It describes retrieving messages through the API or receiving them in real time using SSE.
What API quota does the documentation state?
The documentation sets a general API quota of 8 queries per second per IP address. This is the stated general quota; API users should also account for the documented conditions governing how the API may be used.
What API-use conditions does the documentation list?
The documentation requires API users to link back to mail.tm somewhere visible.
Proceed When Receiving Terms Fit
Fits if temporary receiving meets the task, the stated retention period works, and the API conditions match the intended use.
Probably not if the workflow needs outbound email or messages retained beyond the stated period.
Main risk is building around mailbox access without accounting for message expiry, the API quota, and the documented reuse restrictions.
