Mail.tm — about the provider PocketInbox routes through
Mail.tm is the highest-quality free temp-mail provider available in 2026. PocketInbox uses it as the default backend.
Why we use Mail.tm
Authenticated REST API, JWT-based auth, Mercure SSE push for real-time delivery, fast inbox creation, high deliverability — Mail.tm hits every box.
- Time to inbox: ~150 ms
- Time to first message: 2-4 s
- Deliverability: high (newer domains, less blocked)
- Custom domains: paid only
- Rate limit: 8 QPS shared across IP
When to switch to a different provider
When Mail.tm rate-limits (8 QPS shared budget), PocketInbox switches to Mail.gw (its sister service) automatically. If you need a different domain pool, manually switch in the UI.
FAQ
- Is Mail.tm safe?
- As safe as any free temp-mail service. Don't use it for security-critical mail; do use it for one-shot verification.
