As a major email service provider, Mailgun recognized the importance of security in their business, particularly when handling large volumes of email for prominent brands. To address this, they partnered with Bugcrowd to leverage crowdsourced testing and improve the quality of their bug reports. This collaboration has enabled Mailgun to accelerate their turnaround time for fixes, prioritize issues more efficiently, and gain fresh perspectives from external researchers. With a public partnership announcement, Mailgun is now inviting developers to participate in their security vulnerability program, offering rewards ranging from $100 to $1,500.
