ComePost Inviter Telegram Bot

You launched a channel, paid for ads, traffic is coming in, and the new subscribers say nothing. People tap Subscribe and vanish, and you never learn who they were. ComePost | Inviter greets each newcomer, checks them with a captcha and keeps their contacts for future mailings.

It is built for channel and group owners who are tired of doing all of this by hand.

Five jobs the bot takes over

The bot's own description lists what it does:

• Welcome and goodbye messages. A note for people who join and for those who leave.
• Channel admission. Automatic approval of join requests.
• Captcha. A check that filters out fake accounts.
• Audience base and mailings. Collecting those who came in and sending them bulk messages.
• Analytics. Statistics on how your audience arrives.

Open the menu with /start and set everything up with buttons. 🛠️

How join requests work

This approach starts with an invite link that has join requests turned on. A person follows it and sends a request instead of entering right away.

The admin bot sees that request, can approve it, and can message the person privately at once. That matters because Telegram only lets a bot write first to someone who sent a request or started the bot.

The usual setup for services like this looks like this:

1. Add the bot as a channel admin with permission to invite users.
2. Create a link in the invite links section and enable join requests.
3. Write the greeting and add buttons if you want.
4. Share the link in ads, social networks or on your website.

Why a captcha helps

Ad campaigns and boosting services bring a lot of fake accounts into a channel. They skew reach and statistics, and sometimes your reputation too.

A captcha asks the newcomer to press a button or solve a simple task. A real person manages in a second, while a script usually gets stuck. ✅

The subscriber base: how to avoid harm

A mailing to a collected base hits harder than a regular post because the message lands in a private chat. That is exactly why it is easy to overdo.

• Write with a reason. An announcement, a useful guide, an offer. Never more often than people expect you.
• Offer a way out. If someone asks you to stop, stop, or expect complaints.
• Do not buy bases. Mailing people who do not know you ends in blocks quickly.

What to check before launch 🔍

The bot needs admin rights, so look at exactly which permissions it asks for and do not hand over extras. Greetings do not require deleting messages or banning people.

Check the plans and mailing limits inside the bot itself. They can change, and the menu gives the current picture.

What to put in the greeting

Almost everyone reads the first message, so do not waste it on a bare "Welcome!". Say what the person gets in the channel and suggest a first step: read the pinned post, grab a gift, ask a question.

A short text with one button beats a wall of words. Look at the message on a phone before you switch it on for everyone. 📩
