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, accept all, unknown or disposable.
  • Emails sent via freemail providers such as, but not limited to, Gmail, Hotmail, Outlook, AOL, or Yahoo are not eligible. Freemail providers have a high propensity of false bounces.
  • 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.

To submit a case for guarantee review, please provide the following via email to support@neverbounce.com:

  1. The Job ID in question processed through NeverBounce
  2. The date and time of sending
  3. The categories sent to (valid,accept all, etc)
  4. An export of your full mailing containing all emails sent to and their bounce responses
