What Susan Thinks About Our Email Verification System

Our email verification platform has welcomed thousands of customers from all over the world. Many of them leave us reviews for which we’re happy and grateful. Every once in a while, there’s one review that truly stands out. We decided to share them with you on social media, so here is the latest review that made our day! 

Why people like our email verification system

“We are a market research firm and utilize the client’s customer lists when we send surveys on their behalf. In this case the client had done a poor job of maintaining the customer list, and our survey software rejected the list due to an estimated 11% bounce rate. ZeroBounce to the rescue!

We had never used them before, but within about an hour the list was cleaned and verified. The final bounce rate with the cleaned list was only about 0.6%. This is much more efficient for us and they turned this poor list into something usable. Will be using them with future lists. I was impressed.”

Thank you so much, Susan from OpinionWorks, for your fantastic feedback!

Email verification: it’s what makes the difference

If you have an email list, you know how important email hygiene is.

Invalid and fake email addresses are risky, as they impact your sender reputation. Also, they will affect your email deliverability, as email service providers don’t trust users with messy databases. So, you’ll notice that many of your emails are going to the Spam folder or never reach their destination. This is where email verification makes a difference.

By removing risky contacts from your list, an email verification system helps you boost deliverability and improve your sender reputation. It has become a crucial step, especially for companies that use email marketing.
