How to verify your mailing list

  • Navigate to verifier section

    Log in to your SendPulse account and choose "Email Verification." If you don't have an account, create one now.

  • Upload your mailing list

    Upload your mailing list or choose an existing one and click "Verify." You can also validate a single email address.

  • Get a detailed report

    After verifying your mailing list, you will get a report with not only “valid” and “invalid” addresses on your list, but the system will create a separate mailing list containing all of the valid email addresses. You can add custom variables and segments to your new mailing list.

Verification ensures that you only email quality addresses

Even if you collect subscribers’ email addresses legally, your mailing list may contain invalid email addresses. Verify the addresses on your mailing list before sending an email campaign. Especially if any of the following cases apply to you:

I haven't sent emails in a long time

Remove outdated addresses as they may have become invalid. Some people may have changed their email provider, their place of work, or abandoned their email address.

I collected email addresses using single opt-in

If your subscribers haven’t verified their email addresses through a link in an opt-in confirmation email, there’s a chance that non-existent addresses with spelling errors or typos ended up on your mailing list.

My campaigns have a low delivery rate

If you see a lot of "Delivery failed" or "Email address doesn’t exist" messages it's time to verify your list.

I added email addresses to my mailing list manually

When manually adding contacts, typos may occur — spaces or invalid characters, missing “at” sign, and so on.

If you want to check more than 100 email addresses, choose a paid pricing plan. With our flexible pricing plans, you can find a solution that suits your needs: the price of verification depends on the number of email addresses on your mailing list. The more email addresses you have, the less you pay for each verification.


It’s a tool that helps check your mailing lists for validity and authenticity.

Incorrect email addresses, outdated email addresses, and spam traps increase the number of soft and hard bounces, which hurt your email deliverability and sender reputation. As a result, some email services can block your sender address. To keep your reputation and deliverability high, you should take care of your mailing list hygiene.

With our email verifier, you can check a single email address or an existing mailing list or upload a list of addresses from the file. After the verification, you’ll see the statuses of the verified email addresses. They can be valid, invalid, and unconfirmed. For more details, follow this article.

If you haven’t deleted invalid email addresses after the verification, campaigns won’t be sent to these addresses. Go to your mailing lists and select the verified mailing list. Click “Create a campaign” inside the mailing list. Enter your sender information, choose an email template, and check your settings. Your email campaign is ready for sending.

Our tool lets you check up to 100 email addresses for free per month.

We offer monthly subscriptions and payment for verified addresses. Buying a monthly subscription, you’re charged for a fixed number of addresses you want to check per month. For example, verifying 1,000 addresses costs $15 per month. Alternatively, you can pay for a specific number of verifications. They’re valid for a year. For example, verifying 5,000 addresses costs $50.
