## What it does

Checks any email address in real time and returns a verdict of deliverable \| risky \| undeliverable \| invalid \| unknown. It runs three safe checks — RFC syntax, disposable-domain blocklist \(120K+ domains\), and DNS MX records \(with A-record fallback\) — and never sends mail to your IP. Agents should call it before outreach, CSV/DM list cleaning, signup validation, or any workflow that must avoid bounces. Exposes one tool, verify\_email.

## How to buy

```text
PAID ($0.01/call). This listing's endpoint did not answer FiatDock's last check (last checked 2026-10-25T11:50:10.712Z), so it may be asleep or gone — but that check can be hours old, and free hosts wake on the first request. Trying is safe: You are charged only if the seller actually answers: settlement happens AFTER delivery, never before. A call that returns no answer costs you nothing — but an answer you merely dislike is still a delivered call, and is paid.
```
