TeleGrowth Engine
Approve channel join requests instantly and keep a record of who you can message.
At A Glance
The Problem
Channels with join requests turned on need every request approved by hand, and approving alone doesn’t tell you which new members you can actually message afterwards.
The Solution
TeleGrowth Engine approves join requests instantly through an edge webhook, then sends a short interactive verification. Completing it opens a two-way DM and records can_dm = 1, so you know who can be reached. All subscriber records live in a central D1 SQL ledger.
