2 free lookups a day, no account needed.
What you learn about each address
| Check | The question it answers |
|---|---|
| Format | Is this written like a real address? |
| Domain accepts mail | Is mail set up on this domain at all? |
| Mailbox | Does the mail server confirm this mailbox? |
| Disposable | Is it a throwaway inbox? |
| Role inbox | Is it a shared address such as info@ or sales@ rather than a person? |
| Accept-all domain | Does the domain say yes to every address? |
How to read the result
The mail server confirmed the mailbox.
The server wouldn't give a clear answer, which is common on catch-all domains. Credits are refunded.
The mailbox doesn't exist, can't receive mail or is a throwaway inbox.
What it costs
0.4¢ per check, with no subscription. When we confirm a mailbox on an accept-all domain, that check costs 2¢. Couldn't verify results are refunded.
| Checks | Cost |
|---|---|
| 1,000 | $4 |
| 10,000 | $40 |
| 100,000 | $400 |
Totals assume no accept-all confirmations. Each of those costs 2¢ instead of 0.4¢.
Where teams use it
- Before a campaign, run the whole list through the bulk email verifier so bad addresses don't bounce and hurt your sender reputation.
- On signup forms, call the REST API when someone signs up, so a typo or a throwaway inbox gets caught before the account exists.
- For one-off checks, test an address from an old CRM export or a business card before you write to it.
Questions
How do I check if an email address exists without sending a message?
Use a verifier like this one. It tells you whether the mail server confirms the mailbox, and no message goes out. The form above runs 2 free checks a day.
Is this email verifier free?
You get 2 free checks a day on this page with no account. After that it costs 0.4¢ per check.
What is the difference between email verification and email validation?
Most vendors use the two words for the same thing. When there is a difference, validation means checking how the address is written and whether the domain takes mail, and verification adds a check on the mailbox itself.
How accurate is it?
A Verified result means the mail server confirmed the mailbox at that moment. We don't promise 100%: mailboxes close, and some servers accept a message and bounce it later. If we can't get a clear answer, you see Couldn't verify.
Why can't some addresses be confirmed?
Some domains accept mail for every address, so the server's answer proves nothing. Read what a catch-all email is. Other mail systems simply refuse to answer.
What is a role inbox?
A shared address such as info@, sales@ or support@ that belongs to a team rather than a person. We flag these so you can decide whether they belong on your list.
