Best Telegram bots for Welcome messages & rules

A greeting bot or a group manager

For a small chat a dedicated greeting bot like HelloUserBot is enough: one message with formatting, no menus to learn. Once a group grows past a few hundred members, spam and raids arrive, and a group manager such as Rose or Group Help gives you the greeting together with captcha, anti-flood, word filters and warn/mute/ban commands. Switching later is painful because members must pass the new captcha, so pick the manager early if growth is the plan.

Writing a welcome that works

Keep the greeting short and put the rules behind a button or a command rather than in the message itself. Mention what the group is for and what gets you removed. Set the greeting to delete itself after a few minutes, otherwise a busy group's history becomes a wall of welcomes. A captcha button stops most bot accounts; puzzle captchas annoy real people and rarely stop determined spammers.

Rights and privacy

Give the bot admin rights only for what it does: delete messages and restrict members, not add admins or change group info. Group managers store member lists and settings on their own servers; read the bot's privacy notes if the group is private. Rose's federations link many groups to one ban list, which is useful for a network of chats and dangerous if you share a federation with strangers.
