The problem

Fraudsters don't sign up with their real email. They use disposable domains, five-minute inboxes, and burner addresses, and every one that gets through gets to probe your product, abuse your free tier, or test stolen cards behind a fake identity.

With Encrata

Encrata flags disposable and throwaway domains in the same call that verifies deliverability. Wire it into your risk pipeline: a disposable address alone might just add friction (require a real address), while combined with other signals it's grounds to block. The check costs 1 credit, orders of magnitude less than one chargeback.

How it works

1

Send the address

Call the validity endpoint with the email address at the moment it enters your system, a form, an import, a checkout.

2

We ask the mail server

Encrata checks syntax, domain and mailbox directly with the receiving server, and flags disposable and typo domains.

3

Act on the verdict

Accept, reject or suggest a correction based on a clear valid / invalid / catch-all / risky verdict. One credit per check.

One call, structured answer

Fraud Screening runs on the email validity lookup at 1 credit per lookup. Same API key, same JSON shape as every other Encrata lookup.

  • Answers come from the mail server itself, not a guess from patterns
  • Disposable and throwaway domains are flagged before they cost you anything
  • 1 credit per check, cheap enough to run on every address you touch
  • Cached results are free, so repeated checks never double-charge

}

One signal in your risk score

Treat the validity check as one signal in a scoring pipeline, not a binary gate. A disposable domain adds heavy risk weight; a brand-new free-provider address adds a little; a corporate address with a person behind it subtracts. Encrata's response gives you the raw material, disposable flag, provider classification, domain age via domain_info, to weight however your risk model needs.

Less noise for your analysts

Fraud teams typically see two effects: the obvious one (burner-address signups stop converting to abuse) and a subtler one (analysts spend less time on manual review, because the disposable flag resolves the easy cases automatically). Keep the threshold adaptive, fraudsters rotate domains fast, but the detection corpus updates continuously, so new burner services get caught without you maintaining blocklists.
