Features

Five layers deep. Every single email.

Plus bulk CSV, a real-time API, a native MCP tool for AI agents, and a dashboard that shows your work.

The verification pipeline

Each layer catches what the previous ones miss.

1 · Syntax validation

RFC-style format checks run first and cost nothing extra — typos like gmial.com, missing @ signs, and malformed addresses are rejected instantly.

2 · Disposable-domain detection

We screen against a curated, updated list of throwaway-email providers. Temporary inboxes are flagged so they never pollute your list or trial funnel.

3 · MX record lookup

We query DNS for the domain's mail exchangers. A domain with no MX records can't receive mail at all — those addresses are dead on arrival.

4 · Role-account detection

Addresses like info@, support@, and sales@ bounce more and engage less. We flag them so you can suppress, segment, or treat them deliberately.

5 · Live SMTP handshake — the layer that matters

A dedicated prober opens a real SMTP session with the receiving mail server and asks, via RCPT TO, whether the mailbox exists. We disconnect before any email is sent — nothing is delivered, nothing lands in spam. This is the check that separates real inboxes from plausible-looking fakes, and it's included in every verification.

However you work

One credit balance across every surface.

Bulk CSV upload & download

Drop in a CSV of thousands of addresses — Clay/Apollo exports, CRM dumps, purchased lists. We verify them in the background and you download a clean CSV with verdicts and reasons per row.

Real-time API

POST /api/verify returns a job in milliseconds; poll for the verdict. Validate addresses at signup, checkout, or inside your own product — with 402/429 semantics your developers already understand.

MCP tool for AI agents

A native Model Context Protocol tool (verify_email) lets AI SDRs and agents verify recipients directly — no glue code. Syntax through role checks run in-tool; the full SMTP handshake runs via the REST API.

API keys

Create and revoke per-project keys from your dashboard. Keys are hashed at rest and shown once — rotate anytime without touching your account.

Dashboard analytics

Plan, credit balance, usage history, and per-key activity at a glance. Export any result set to CSV whenever you need an audit trail.

Anonymous free tier

No signup needed for quick checks — 10 verifications per day per IP, right from the homepage widget.
