TMailr
TMailr combines receive-only temporary inboxes, masked forwarding aliases, email deliverability checks, and a developer sandbox on the web and through an API. Temporary inboxes use private links, receive mail only, and disappear when they expire. Free inboxes last 60 minutes by default, can be extended to 24 hours, and hold up to 50 messages; Pro inboxes are described as effectively unlimited and remain active while subscribed. Masked aliases forward messages to a real mailbox, can be paused or blocked separately, and keep the forwarding address out of TMailr pages and API responses. Deliverability tools include Gmail inbox tests, domain checks for MX, SPF, DMARC, MTA-STS, and TLS, plus header, address, and DMARC tools. Developers get test and live keys, JavaScript examples, polling, and signed webhooks. Incoming HTML is sanitized, remote images are blocked until requested, links show destinations, and attachments are virus-scanned; executable files are refused.
