Stop reading statuses.
Start asking.
Every other verifier hands you a wall of codes to decode. Ours reads your list, answers in plain English, and does something about it. Upload, then just ask: “Is this safe to send?”

Ask one question. Get a real answer.
No CSV gymnastics. The assistant reads the whole list, grades it, and tells you what to do — with the numbers right there to back it up.
Deliverability grade on list #4821 — graded from real verdicts, not a guess.

What a catch-all means for your send.
A status code is trivia. A recommendation is value. The assistant turns every verdict into a next step — and is honest when a result is uncertain instead of faking a green light. Not a green light. An answer.
- Catch-all?“Acceptance can't be confirmed — send to a low-risk warmup segment.”
- Typo?“Did you mean gmail.com? I can fix and re-verify it free.”
- Unknown?“Likely greylisted — free to re-verify for a clearer result.”
Put verification inside your agents.
The same tool layer that powers the in-app assistant is exposed over Model Context Protocol. Point Claude Desktop or a custom agent at one URL and it inherits all 14 tools — scoped by key, metered by credits, confirm-first on anything billable or destructive.
- One config block — no SDK, no glue code, no per-tool wiring.
- Scoped & metered — keys you can revoke, spend you can cap per agent.
- Same guardrails— agents can't spend a credit past your ceiling without a yes.

// Your agent now has 14 scoped tools:
// verify_email · grade_list · find_email
// list_jobs · read_analytics · sync_integration …
// every billable call is metered by credits,
// every destructive call is confirm-first.It always asks before it spends.
No silent charges, no surprise deletions. Every billable or destructive action is proposed with its exact credit cost and waits for your yes. Unknown verdicts stay free — you only pay for answers we're sure of, and credits never expire.
- Exact cost up front — shown in credits, before anything runs.
- One-click approve — or tweak the scope and ask again.
- Fully logged — every agent action is auditable after the fact.
Re-verify the 4,230 unknowns in list #4821 and export the clean set.
An assistant that acts — safely.
Verify, clean, segment, export, sync. It proposes every billable or destructive action with its exact cost and waits for your yes.
Confirm-first by design
It never spends a credit or deletes a thing without showing you the cost and getting your approval first.

“Find Jane's email at acme.com” — done.
The part teams actually love.
We cut our bounce rate from 11.4% to 0.5% in a week. The AI explaining why each address was risky is the part our team actually loves.
The API drops straight into our signup flow. Fake and disposable emails never make it into the database anymore.
Half the price of the tool we left, and the inbox-placement testing paid for itself on the first campaign.
Good to know.
