Bug Bounty disclosure program

Omnisend looks forward to working with the security community to find security vulnerabilities to keep our business and customers safe. If you believe you've found a security issue, we encourage you to notify us.


  • Please provide detailed reports with reproducible steps. If the report is not detailed enough to reproduce the issue, the issue will not be eligible for a reward.

  • Submit one vulnerability per report unless you need to chain vulnerabilities to provide impact.

  • When duplicates occur or known vulnerabilities, we only award the first report received (provided that it can be fully reproduced).

  • Multiple vulnerabilities caused by the same underlying issue will be awarded one payout.

  • Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our services.

  • Test vulnerabilities only on accounts you own or have explicit permission from the account holder.

  • Report Wordpress plugin vulnerabilities to Patchstack.
