About Sarah
Sarah is a cybersecurity expert with over 10 years of experience in email security and privacy protection. She leads security research at Temp Postal, where she studies how disposable email services are abused by spammers and fraudsters — and how to stop them without punishing legitimate users who simply want to protect their primary inbox. Before joining Temp Postal she worked on anti-phishing systems for a major email provider and spent several years in incident response, investigating business email compromise campaigns that almost always began with a throwaway address. She has contributed to multiple open-source privacy projects and regularly reviews the GDPR, CCPA and data-retention implications of the features the team ships. Her writing focuses on threat modeling for ordinary people: what data a signup form actually exposes, how email tracking pixels work, and when a temporary address is the right tool versus when a full alias service makes more sense. Sarah believes privacy tools should be boring, predictable and honest about their limits, and she holds every Temp Postal feature to that standard.
