Results

By using ZeroBounce, the team at Image Source was able to get a clear breakdown of their data and find out why it wasn’t performing.

Below you can see the results of the email verification test Bruce Herwig ran (10% of the list).

Herwig went on to clean the entire Image Source database. The image below gives you an even better perspective of the email list quality – it’s easy to understand why Image Source’s emails were getting a 19% bounce rate.

ZeroBounce found more than 21,000 invalid email addresses, 28,524 catch-all emails, and 139 abuse emails (users who were likely to mark emails as Spam). On top of that, more than 4,000 emails were “do not mail” – meaning they were probably toxic, disposable, or role-based.

"ZeroBounce has superb customer support. When I reached out with questions, I received a quick answer and a phone follow-up"

“There is great peace of mind knowing that the emails that you are sending to have been verified and that old and outdated emails have been filtered out. As our email reputationⓘAlso referred to as ‘Sender Reputation.’ This describes how trustworthy a sender is when sending emails. Reputation is influenced by past campaign performance and sending habits, including bounce rate, spam complaints, abuse reports, email authentication, sending volume, and domain history. improves, we’re seeing a slight increase in deliverable and open rates. We expect this to continue,” says Bruce Herwig.

A.I. Email Scoring

Once he validated the entire email list for Image Source, Bruce Herwig went on to try the ZeroBounce A.I. email scoring system.

The service uses artificial intelligence to further validate catch-all emails and rate the overall quality of an email address. Thus, it helps marketers gain perspective on how subscribers will interact with their emails.

Overall Experience

"By adding the ZeroBounce scoring to our contacts, we’re able to control the blend of verified and low scoring emails in a campaign. This lets us email strategically and systematically without blowing our reputation scores."

Lastly, we asked Bruce Herwig what his overall experience with ZeroBounce was.

“I appreciated the education I received from the ZeroBounce website and blog, and the clear step-by-step process suggested. Uploading our database was easy and the categories you get in the results are easy to follow. Also, ZeroBounce has superb customer support.
