GuestPostMailer Chrome Extension is built to simplify and automate the entire guest posting workflow directly inside Gmail. Instead of manually switching between tools, spreadsheets, and CRMs, you can manage deals, process link insertion or guest post orders, and track invoices—all without leaving your inbox. 

From the very first client email to the final invoice payment, GuestPostMailer ensures faster communication, accurate tracking, and smooth collaboration. With AI-powered replies, duplicate detection, and smart invoicing, it takes the manual effort out of guest posting and gives you a streamlined, reliable process. 

✅  Real-life Example
Imagine a content manager who receives dozens of guest post inquiries every week. Managing deals, keeping track of payments, and following up manually quickly becomes overwhelming. With GuestPostMailer, every step—from replying professionally to creating deals and sending invoices—happens right inside Gmail. No extra tools, no missed opportunities, no revenue leakage.
