caveatanonymousno cardMper-object-cap
| Free tier | a disposable inbox with a 40 MB quota, created and read over a keyless REST API unit MB; metered on stored-bytes |
|---|---|
| Price | none stated |
| Per-object cap | 40 MB quota per inbox, reported by the account object |
| Retention | messages persist until the account is deleted; no expiry is stated |
| Egress | not applicable: receive-only |
| Identity | anonymous no key, no email verification and no card; measured by creating an account |
| Limits |
|
| Binding | per-object-cap |
| Interface | rest /domains, /accounts, /token and /messages on api.mail.tm; SMTP delivery to in.mail.tm |
| Tooling | curl, any HTTP client |
| Composes with | the verification-code sink, measured end to end: create an inbox with no key, let a service deliver over SMTP, read the message back over the API. The scarce link is the 40 MB quota and the single shared domain. |
| Reliability | one active domain; a domain change would invalidate every address a script had recorded |
| Notes | Four requests and one SMTP message proved the whole chain. 25 MiB per message against a 40 MB inbox is the practical ceiling, so one inbox holds one message. |
