Purpose

Our top priority is the security and confidentiality of our customers. We try as much as possible to write clean code and perform thorough testing. Despite our best efforts, vulnerabilities may still be present in our services.

Everyone is encouraged to report identified vulnerabilities. Sendinblue will make the best effort to respond as fast as possible. Please allow a few days before messaging us again.

The preferred method for contacting Sendinblue security team and reporting vulnerabilities is by sending an email to disclosure@sendinblue.com.
