Our Guarantee

Last updated:

NeverBounce is extremely confident in providing the highest level of accuracy when cleaning lists of any size. In doing so, we are proud to guarantee that no more than 3% of your emails will bounce after using our service. Should your bounce rate exceed 3% after sending only valid emails, 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.
