NeverBounce is extremely confident in providing the highest level of accuracy when cleaning lists of any size. In doing so, we are able to offer a 97% accuracy guarantee that your valid emails will not bounce after cleaning them using NeverBounce. Should more than 3% of your valid emails bounce after using our service, we will refund the difference back to you.
In order to meet this guarantee, the following is required:
- The list must have been cleaned by NeverBounce within 72 hours of being mailed to.
- The list must contain a minimum of 500 unique email addresses.
- Our guarantee only covers mailing to deliverable addresses and not to those that have been categorized as invalid, catch-all, unknown or disposable.
- Bounces due to internal technical issues, sender reputation, or similar technicalities will not qualify for our guarantee.
- Email addresses that bounce must be indicated as invalid.
