Vulnerability Disclosure Policy
If you have found a vulnerability on of the Block Sender products (i.e. dashboard, API, Chrome extension, etc.), we encourage you to submit your report to us as soon as possible and to not make the vulnerability public until it has been fixed and verified by Block Sender.
While we greatly appreciate vulnerability disclosures from the community, no compensation will be given.

- Do not submit reports from automated exploit scanning tools without first confirming the issue is in fact present.
- Do not contact Block Sender employees or users for the purpose of phishing or social engineering.
