Check any address before you send to it. Valid, invalid or catch-all, in a few seconds. No signup, 10 checks a day.
We look up the domain's mail servers and ask them whether the mailbox exists, without sending an email. Several verification services are tried in order until one gives a definite answer.
Some domains accept mail for every address, real or not. Nobody can confirm a single mailbox on those domains, so we say catch-all instead of pretending it is valid.
Yes: 10 checks a day, no account. To verify a whole list, upload a CSV in a free account: one credit checks 10 addresses, and new accounts get 50 credits.
We don't store the addresses you check here. To prevent abuse we keep a salted hash of your IP address for 24 hours, never the IP itself.
Describe what you sell. SenseCollect finds the companies that fit, the decision-maker at each one and a verified email, and you only pay for what's found.
