Our verdict on TMailr
TMailr combines disposable temporary inboxes, permanent masked aliases, custom-domain aliases, and email testing in one web-based service. It suits people who want to keep their real address private while also checking message delivery, domain configuration, or application email flows. Permanent aliases forward messages to an existing mailbox, while temporary inboxes hold messages that expire. Developers can also use sandboxes and API access for application and CI workflows.
The Free plan includes browser inboxes, masked aliases, 10 deliverability tests per month, and no account or card requirement. Pro costs $2.99 per month or $24 per year and adds persistent disposable inboxes, retention of inbox messages and attachments while subscribed, and up to 25 custom domains. The Free plan supports 1 custom domain. Pay as you go costs $10 for 120 credits for API use and deliverability testing, with credits that do not expire. The $9-per-month API plan adds a monthly credit allowance and higher API limits.
TMailr’s strongest distinction is its testing depth alongside address privacy. Features include domain health checks for MX, SPF, DMARC, MTA-STS, and TLS; verification-code extraction; safe message viewing with blocked remote images and raw headers; a header analyzer; an email checker; and a DMARC generator. Users who need aliases for receiving, forwarding, pausing, or blocking should find the feature set well aligned. It is less suitable for workflows that require sending or replying from an alias, because those capabilities are not supported.
