Throwaway email detection API

Use a throwaway detector to catch short-lived inboxes before they enter your system.

Throwaway mail is common in free trials and spammy lead capture.
It is a strong signal when the same domain appears across many bad signups.
You can block it outright or fold it into a risk score.
curl -X POST "https://your-domain.com/api/v1/[email protected]" \
  -H "X-Api-Key: ev_your_key_here"

What makes it throwaway?

Short-lived providers, temporary routing, and abuse-heavy patterns.

Should I allow it?

Usually only if your product explicitly accepts anonymous or temporary email use.

Why disposable detection matters

Disposable inboxes distort activation metrics, increase support noise, and make abuse easier. A disposable detector is most useful when it runs before account creation, not after the user has already entered your system.

What makes a strong detector

A useful implementation combines a maintained domain list, DNS lookups, and risk scoring. That reduces the chance of relying on one stale signal and gives you a cleaner block-or-warn decision.
