ZeroBounce Gurantees an minimum of 99% Accuracy
Minimum Accuracy Is 99%
Other companies say it, we put it in writing. ZeroBounce, the leader in email validation, makes you the promise of cleaner and safer email lists.
We guarantee the following accuracy rates at a minimum:
96%+ Accuracy rates on AOL, Yahoo, and office 365 email accounts.
99% Accuracy rates on everything else.
How the Guarantee works:
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.
In order to qualify for the guarantee, the following conditions must be met:
You only email the _valid.csv and remove all toxic and disposable domains.
You email the list within 72 hours after cleaning.
Bounces must be invalid emails (Hard Bounces).
Bounces due to spam content, blacklisted IP's, technical Issues, Invalid Mail Configuration, throttling, etc do not qualify for the guarantee.
The minimum list size must be 1000 emails.
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.

Solid
I uploaded a few big lists that I’d collected over time, expecting the usual mess of false positives and “unknown” results. Instead, ZeroBounce cleaned them up with impressive accuracy. Deliverability improved almost immediately once I switched to using only their verified emails. The integration with Mailchimp and other platforms was seamless, which saved me hours of tedious work.
The part that really surprised me is how transparent they are about what each category means. You can tell someone actually thought about how marketers use this stuff in real life. I also like that their support team responds like actual humans, not robots sending canned replies.
It’s not the cheapest service out there, but when your reputation and sender score are on the line, it’s easily worth the price. If you care about keeping your email list healthy, ZeroBounce is the one to trust.

Great product, I trust it more than others
Great product, I'd say they are a bit more stringent than other email verifiers, so I get a lower yield, but I trust the results more. I like to use this as my last line of defense in a triple verification sequence.
