FAQ - Email Verifier Tool
What does Snov.io Email Verifier do?
Snov.io Email Verifier is a tool that clears your email list from invalid emails.
We recommend sending only to verified emails, as invalid and abandoned emails can lead to high bounce rate, lower sender reputation, and subsequent blocking by the ESPs. Our Email Verifier will maintain the high sender reputation of your email account by improving the delivery rate of your campaigns.
How accurate are the email verification results?
It is not possible to check an email’s validity with 100% accuracy without sending an actual email to it. However, the bounce rate for emails that have received a “valid” status after email verification with Snov.io is only 1.72% (according to our latest testing results). That means that you’ll keep an average deliverability of up to 98% with our email verifier.
Do you send an email to verify an email address?
Snov.io does not actually send any emails to verify an email address. Instead, we use 7-tier verification.
How are email addresses verified by Snov.io?
We use a 7-tier verification process to check email addresses:
- Syntax check defines if an email address is spelled correctly, all the necessary symbols are in the right order, and the symbols used are allowed.
- Gibberish check identifies the randomness of an email defining how likely it is to be invalid or disposable.
- Domain existence check tests if the domain the email is tied to actually exists.
- MX record check tests if 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 check if an email address actually exists, that allows us to give more accurate and relevant results.
- Catch-all domain check detects if the server has a catch-all policy that accepts all the email addresses.
- Freemail check defines if it is a custom business email or an ordinary one.
