Before launching your campaigns, you want to make sure that all the leads have been verified. High bounce rate may have a negative impact on your sender reputation.

The email gets hard bounced and fails to get delivered permanently if it has been sent to a non-existent address. All these addresses should be removed from the list so that your sender reputation does not get affected due to poor email deliverability.

For this reason, you want to clean your list with some of the email verifiers and there are plenty available on the market. The two that we will show you how to use are Bulkemailchecker and MillionVerifier.

Verifying the leads with Bulkemailchecker

The bulk verify system allows uploads of any plain text csv or tab delimited list of emails to be bulk verified.

Login to your account and go to Bulk Verify page.

Upload your lead list by clicking on the Choose File, and if it contains data other than just email addresses, click on the second option:

Click on Upload.

Wait a minute or two for a file to be imported. Be sure to check the status every now and then to get to the next step.

When the import is done, you need to choose the column that contains email addresses. Then, click on Select.

The emails are being uploaded now, and be sure to check the status every now and then to get to the next step.

Lastly, you want to confirm and pay the number of credits for verification to start. You can pay additional credits to speed up the process too.

Be sure to check the status to get to the last step.

Finally, you can export your file by clicking the Export button and selecting Spreadsheet.

Verifying the leads with MillionVerifier

Log in to your MillionVerifier account.

Click & upload or drag & drop your file congaing your contacts:

Click on Start Verify.

Track the number of emails in the queue, when it gets down to just a few, it is safe to finish the search and download the list.

Click on the stop button to finish the search in case you don't want to wait for the last email to get verified which can take a lot of time.

MillionVerifier will offer you to download the email addresses with different statuses, but the safest is to download the list with only Good Emails which you can go ahead and upload to Instantly.
