If the accuracy rates are below these thresholds, we will refund 5 times the amount for each 1%. Let's say you have a 97% accuracy rate, which is 1% below the guaranteed threshold of (99%+ Accuracy rates on everything else). We will refund 5 x 1% (or 5%) of your total validation cost for those emails. If your accuracy rate is 2% below the guaranteed threshold, our refund will be of 10% of your costs. If it's 4% below, the refund will be 20%, and so on.

This list must be an opt-in list that you collected and not purchased from a 3rd party
You must provide an export of your full mailing of all emails you sent to and their bounce responses (the actual SMTP Codes of the bounces), not your email sender classifying it as a bounce.

Easy to use and improved deliverability - what else would you want?
I was experiencing deliverability issues with emails that were marked as "verified" through a business contact platform. So I researched the best email verification tools, and ZeroBounce was repeatedly mentioned.
I have found it extremely useful for thoroughly checking the status of email addresses.
The user interface is very intuitive and easy to use, and the AI explainers add an extra touch of clarity to the communication about the results from each verification. It has helped me scale up my outreach faster, and I saw an improvement in my email deliverability as a result.

A Must-Have Tool for Any Email Marketer!
I've been using ZeroBounce for over a year now, and it has completely transformed our email marketing efforts. Before, we struggled with high bounce rates, which hurt our sender reputation and wasted our marketing budget. Since integrating ZeroBounce, our deliverability has skyrocketed, and our campaign ROI has seen a significant increase.
What I love most is the accuracy of their validation service. It catches everything from typos and invalid formats to spam traps and abuse emails, ensuring our lists are squeaky clean. The platform is incredibly user-friendly and integrates seamlessly with our existing marketing stack. On top of a fantastic product, their customer support is top-notch – always responsive, knowledgeable, and genuinely helpful.
I can't recommend ZeroBounce enough. It's an essential tool that pays for itself in no time. Five stars all the way!
