I need a focused Telegram marketing application whose primary job is to invite new members into specified channels or groups quickly and reliably. The flow should feel smooth for end-users: they sign up with their phone number, verify once, and immediately gain access to the dashboard where they can launch invitation campaigns. Beyond the invite engine, I also want a light automated-messaging layer tied to those invitations. As soon as someone is pulled into the channel, the system should be able to fire a pre-set “welcome/registration” message so the newcomer is guided to the next step without me lifting a finger. Key points to keep in mind • Phone number registration only—no email or social logins. • Stable, high-volume invite capability that respects Telegram limits and avoids bans. • Simple UI where I can paste a list of usernames/phone numbers, choose the target group, and hit send. • A template manager for that initial registration message so I can edit wording or add links when needed. • Clear logs: number of invites attempted, successful joins, and any failures with brief error notes. Tech choice is open, but I’m comfortable if you lean on Python with Telethon or Pyrogram, or a Node.js alternative provided it delivers the same reliability. I’ll test by running one campaign of 1,000 invites; delivery rate and the automated registration message firing correctly will be the acceptance criteria for sign-off.
