About these numbers
- Disposable domains tracked
- We maintain a continuously-updated database of 120k+ domains that are known disposable, temporary, or throwaway email providers. The set includes the well-known names (mailinator, guerrillamail, 10minutemail, temp-mail, yopmail, tempr.email) plus thousands of smaller / regional / short-lived providers.
- New domains per day
- Automated crawlers find candidate domains; human reviewers confirm before they ship to production. Average of ~~140 new domains land every day.
- Latency
- Median response time (p50) is 47 ms measured against the production endpoint, including the upstream call. The check is in-memory after the first hit, so practical latency is dominated by network round-trip.
- Uptime
- 99.95% since launch. We run on a single Hetzner CX23 box in Falkenstein, Germany (Hetzner FSN1) — no third-party SaaS on the critical path, so our uptime is determined entirely by our own infrastructure.
