How Gmail Auto Reply & Follow-up Works
Connect in seconds with official Google OAuth. No coding, complex webhooks, or local software installation required.
Connect Gmail Inboxes
Authenticate your Gmail or Google Workspace accounts with one click via Google official OAuth. Your access tokens are securely encrypted with AES-256.
Configure Rules & Messages
Craft your initial Auto-Reply and sequential Follow-up steps. Use dynamic variables like {{first_name}}, set custom delay intervals, and define working hours.
24/7 Background Automation
Our cloud engine monitors incoming emails, prevents duplicate traffic, schedules replies, and halts follow-ups immediately when a recipient replies.
Technical Architecture & Deliverability Highlights
Official Google API Compliance
All email operations are conducted via official Google Cloud REST API endpoints using approved OAuth scopes. No insecure IMAP/SMTP password storage.
Native Thread Header Preservation
Replies strictly include In-Reply-To and References RFC email headers, guaranteeing that messages appear seamlessly inside the client's original conversation thread.
Timezone & Working Day Engine
Messages scheduled outside your designated working window are postponed safely to the beginning of the next business day.
Atomic Concurrency Locking
Database-level unique keys and status transitions prevent race conditions even when high volumes of simultaneous emails arrive.
