Please note that the Email Verification Service is currently not available for Custom Branding subaccounts.

Unlimited plans can use the Email Verification Service for free - the verification price is included in the whole plan's package. However, there is a limit of verifiable contacts set up for each contact tier. The limits are:

  • 1 x contact limit for Unlimited

  • 5 x contact limit for Unlimited PRO plans.

For example:

  • Unlimited 5,000 can verify up to 5,000 contacts within the current subscription period.

  • Unlimited PRO 5,000 can verify up to 25,000 contacts within the current subscription period.

The limit resets each month.

Email API and Email API PRO plans are charged $1 for every 1,000 contact verifications.

The above applies to bulk verification. Single email verification is free for all accounts.

Verifying your contacts

You can find the Email Verification Service in your menu under "Verifications".

You can choose to either verify a .csv list in bulk or a single contact.

Bulk Verification

Please note that the .csv you upload should contain only one column named "Email" that is followed with just email addresses.

Just click the "Upload list" button and select your .csv file to verify.

You will be able to find your newly uploaded list under the All or Unprocessed tabs. What's left is to click the "Start Verification" button. Please note that larger files might take more time to process.

When finished, you can view the details of the verification by clicking "View contacts".

Here the contacts have been grouped into four categories:

Valid - Deliverable, legitimate email address

Invalid - Non-deliverable inbox that for some reason cannot be reached

Risky - Valid email address that has some risk factors to it (like a domain with low reputation or known naming patterns that were used by abusers)

Unknown - We were not able to categorize it as any of the above

Single Verification

Single verification works almost like Bulk Verification. The only difference is that instead of using a ready .csv list, a single email address is typed in here manually for verification. The results screen is similar.

Single verification for trial accounts should not be used for verifying more than 10 emails one after another. To verify more, please use bulk verification.


Every verified contact can be clicked to access it's details screen. This screen shows the domain, decides if it is a role address and if it is worth keeping on your account:

We also have our own database of common misspellings in email addresses and we will try to indicate if there is any error in your contact's name along with a proposed solution:

What is checked

The Email Verification Service checks if the domain of your contact is valid by looking up it's DNS records. We also have our own database of known bad addresses or naming patterns that were previously recognized as wrong to cross-check with your contacts.
