Why customers think ZeroBounce is the best email scrubbing tool available

How ZeroBounce helped one company reclaim their email service
At one point, the bounce rate was so high that our ESP canceled our service. Using ZeroBounce’s email verification, we identified the offending fake and invalid email addresses. Our ESP is extremely strict, but once we cleaned our list and they were convinced it was up to date, they reinstated us. Using ZeroBounce, we have an almost zero bounce rate. I guess that’s why you call it ‘ZeroBounce’!

The impact of regular email list scrubbing
We were coming up on a big, important launch for our business, and we wanted to ensure we were only sending emails to legit addresses with real people on the other side of them. We couldn’t afford spam complaints, and we didn’t want to negatively impact deliverability in any way. So, we used ZeroBounce to clean up our email list. For this most recent time – for our own business – we were convinced by past good experiences with the brand and product. We were surprised to find that our list was pretty clean, actually. I think maybe 2% of our addresses were worth scrubbing away.

The best way to zero bounces
We were expanding our email marketing and knew that our list was questionable. After a 19% bounce rate on our last email campaign, we knew we needed to do something. I just wasn’t sure where to start. 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 There is great peace of mind knowing that the emails that you are sending to have been verified and that old and outdated emails have been filtered out.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.
