Check an email address
Free, with no sign-up. We don’t store the addresses you check.
What does each check mean?
| Check | What it tests | Effect on the verdict |
|---|---|---|
| Format | The address is written correctly: a name, one @ and a domain. | Invalid if it fails. Nothing can be delivered to it. |
| Domain | The domain after the @ exists in DNS. | Invalid if it fails. The domain is misspelled or no longer registered. |
| Mail server | The domain publishes MX records, the servers that accept its email. | Risky if it fails: the domain exists but isn’t set up to receive email. Invalid if the domain publishes a record saying it accepts no email. |
| Disposable | The domain belongs to a throwaway email service. | Risky if it matches. These inboxes are temporary and rarely read. |
| Role address | The name before the @ is a shared inbox, like info@, sales@ or support@. | Risky if it matches. It reaches a team or a queue, not one person. |
| Free provider | The domain is a free provider, like Gmail, Outlook or Yahoo. | A note only. It doesn’t change the verdict. |
An address is valid when it passes every check. If the domain can’t be looked up in time, the result is risky and the note says so.
What can’t the verifier tell you?
- Whether the mailbox exists. Only the receiving mail server knows. Asking it means opening an SMTP connection, and many servers refuse to answer or accept every address. We don’t probe mail servers.
- Whether a catch-all domain will deliver. Some domains accept mail for any name, real or not. An address there can pass every check and still never reach a person.
- Whether the person still works there. A valid result means the domain accepts email, not that the address belongs to the person you want.
How should you use the results before sending cold email?
Remove the invalid addresses
They will bounce, and a high bounce rate hurts your sending reputation with mailbox providers.
Review the risky ones
Leave out disposable addresses. Swap role addresses for a named person where you can. Check domains that timed out again later.
Send to valid addresses in small batches
Valid still isn’t proof the mailbox exists. Start small, watch your bounce rate and pause if it climbs.
Prefer addresses with a known source
A guessed address is the riskiest kind. Find contacts in DataPit instead of guessing from a pattern.
Frequently asked questions
Is the email verifier free?
Yes. You can check 20 addresses an hour for free, with no account. To find and reveal contacts, create a free DataPit account; the Free plan includes 800 credits a month.
Do you store the email addresses I check?
No. We look up the domain’s DNS records and send you the result. The address isn’t saved, logged or added to DataPit.
Why is my address marked risky?
Risky means the address might receive mail, but sending to it is a gamble. The domain has no mail server, the address is disposable or a role inbox, or the domain couldn’t be checked in time. The result card says which.
Can the verifier confirm that a mailbox exists?
No. Only the receiving mail server knows that, and many servers block the checks or accept every address. We don’t probe mail servers at all. A valid result means the domain can receive email, not that this inbox exists.
How many addresses can I check?
20 an hour from one connection. After that, the tool tells you how long to wait before the next check.
