Check a company's email before you quote.
An inquiry lands from a company you've never heard of. Paste the address, get a verdict with the reason in seconds — before anyone spends an hour on the offer.
The inquiry looks real. Is the address?
A transport request lands from a company you've never worked with. Someone on your team is about to spend an hour on routes and rates — and the first reply will carry your quote. Before any of that, it's worth thirty seconds to know whether the address can receive mail at all, and whether it's a real company mailbox or a throwaway.
One check returns the verdict with the reason: the domain exists, its mail servers answer, the mailbox was confirmed — or it wasn't, and you know why. What you do with a flagged inquiry stays your call; you just stop doing it blind.
How you do it
Paste the address
Into the free checker — no account needed — or the dashboard if you're signed in.
Read the verdict
Deliverable, risky, undeliverable or an honest unknown, with every check reported: domain, mail servers, mailbox, disposable, shared inbox.
Decide with it
A confirmed mailbox: quote away. A dead domain: a phone call first. The check informs the decision — it doesn't make it.
Scale when it recurs
Fielding many inquiries? Verify in the dashboard with history, or check a whole contact sheet as a CSV.
Product UI shown with sample data.
Every answer is explained — and nobody gets emailed.
Four honest outcomes
deliverable, risky, undeliverable — or an honest unknown when a mailbox can't be confirmed, instead of a confident guess.
A reason for every row
A 0–100 score plus a machine-readable reason (no_mx, mailbox_not_found, disposable_domain…) you can act on and show your team.
No email is ever sent
The mailbox probe talks to the receiving server but always stops before any message — the people on your list never see anything.
What 1,000 checks costs
One credit checks one address. Pay once — credits never expire, and there's no subscription required. The full rate schedule is on the pricing page.
Frequently asked questions
No — the free single-address checker works without an account. An account adds history, bulk CSV checks and the API, plus 500 free credits to start.
Whether the domain exists and can receive mail, whether the specific mailbox could be confirmed, and signals like disposable domains or shared inboxes — each check reported individually, with a plain reason.
The mailbox probe talks to their mail server the way any sender would, but always stops before a message is sent. Nobody at the company sees an email from us or from you.
