Most of the turnkey “Telegram mass‐messaging” apps on the market turn out to be vaporware or outright scams. What actually works for me is either a small custom Telethon/Pyrogram script or one of the few maintained GUIs built on those libraries. You point it at a source group, it scrapes the member IDs (honoring Telegram’s rate limits), and then it walks through your own list of bot or user accounts—each on its own proxy—and sends out a templated DM one by one.
If you’re comfortable with a little Python, grab the official Telethon repo, fork its “add and message users” example, drop in your account session files and proxy list, and you have a rock‐solid, zero-scam solution that you fully control. If you’d rather not code, look for a service that explicitly says “built on Telethon” (most honest sellers do) and asks you for your own API keys so they never hold your login data. A few names that still get genuine reviews are “BotFarm” by KoiSoft and the desktop “Telegram Sender” from MiraiTools—but always test with two or three free trial messages first before you commit.
Bottom line: avoid anything that promises “one-click” bulk DMs without showing you the underlying Telethon/Pyrogram code or requiring your own API credentials. Using a small, self-hosted Telethon script is by far the most reliable way to extract group members and message them safely.
