Clean your email list from invalid emails

Emails sent to invalid addresses bounce back, which may lead to account suspension if the bounce rate is too high.
The bounce rate should stay within the 10-15% threshold.
Upload your list to verify and clean emails. Snov.io can check every email address you have and reduce your bounce rate.

Unparalleled verification process

Format

First, we run a check to make sure the email complies with standard email format rules. Emails with misplaced or forbidden symbols that do not meet the standards are excluded from the list.

Domain

Next, we verify that the domain and the email address associated with it really exist. Catch-all domains are also filtered.

SMTP

Email Verifier pings the server and processes its response to determine the email address status and validity with exceptional accuracy.

FAQ

leads
  • What is the purpose of an Email Verifier?

    Email verifier, or email checker, is a tool that can clean your email list from old or invalid emails. Sending to unverified email lists will lead to a high bounce rate and blocking of your email by ESPs. The goals of our service is to maintain the high reputation of your email account by improving the delivery rate of your campaigns.

  • How accurate are the email verification results?

    There is no way to verify an email with 100% accuracy without sending an actual email to it. That said, according to our latest tests, the bounce rate for emails that have received a “valid” status after email verification with Snov.io is only 1.72%. With our email checker, you can maintain an average deliverability of up to 98%.

  • Do you send an email to verify an email address?

    Email sending is not used for email verification. We use a 4-tier verification process: syntax check, MX record check, SMTP authentification, and catch-all address check. Such multi-tier check guarantees maximum accuracy of email verification.

  • How do you verify email addresses?
    We use a 4-tier verification process to check email addresses:

    - Syntax check determines if an email address is spelled correctly, all the necessary symbols are in place, and the symbols used are allowed.

    - MX record check assesses whether the mail exchange entry listed in the email address is an actual, registered and hosted domain name which can be accessed online.

    - SMTP authentication, or pinging an email address, is a more complex way to verify if an email address actually exists.

    - Catch-all address check verifies if an email address is a catch-all.

  • Is the Email Verifier free?

    Snov.io Email Verifier is free to use on a free account. Free Snov.io accounts receive 50 credits/month for free. You can use the free plan for as long as you need, no credit card required upfront.

  • How much does 1 verification cost?

    1 email verification costs 0.1 credit/email found with Snov.io (you will only be charged if the email is valid) and 0.5 credit/email for uploaded emails (you are only charged for emails with valid or invalid status).

  • Can you verify any email?

    We will verify most email addresses, including custom domain emails. We do not verify emails from catch-all domains.

  • How fast is your Email Verifier?

    Our email address verifier can clean hundreds of emails in a matter of minutes. Bigger lists of up to 50,000 emails will take up to an hour. We will send you an email notification once your verification is complete.

  • Do you share my email lists or use them in any other way?

    We do not share your lists with anyone. The lists you create or upload are safely stored only for your use.

  • Do you have an email verifier API?

    Yes! You can call our API methods to verify single emails or bulk lists without opening the application. This API method is free. You can find more details on Snov.io Email Verifier API here.

  • Can I verify email addresses in bulk?

    Yes, you can! Our bulk email verifier is available in the app or as an API.
    Bulk email address verification can be performed right in the email verifier tool: simply upload your list or find emails with our Email Finder tool and start email list verification.
