What is The Reply Project?

GMass extends Gmail's send limits and automates mass email campaigns with mail merges sourced from Google Sheets. It provides campaign analytics that share reports on opens, clicks, and replies, and supports personalized mail merges and conditional logic for targeted messaging.

Automated follow‑up sequences, scheduling, and email polling add workflow efficiency for sales, marketing, and outreach teams. Reply management, unsubscribe and bounce handling reduce inbox clutter and maintain list hygiene. Email list building, AB testing, and SMTP integration allow users to create targeted lists, test variations, and send beyond Gmail’s restrictions.

Transactional and verification tools ensure reliable delivery, while templates and a REST API enable reuse and integration with third‑party apps. These features serve marketers, sales professionals, recruiters, educators, and other users needing scalable, deliverable email outreach from Gmail.
