Telegram Bot API

Free messaging to phones via a bot; the cleanest no-cost notification channel

The Telegram Bot API lets you send and receive messages, photos, files, and rich interactive content through a bot you create with @BotFather. It is free of charge with no usage tier, making it a popular zero-cost way to deliver notifications and build chat-driven automations.

Free, no billing; you only need a bot token from @BotFather (paid broadcast is optional, opt-in)

Rate limits

Roughly 30 messages/second overall and ~1 message/second to a single chat; ~20 messages/minute to a single group. Excess returns 429 with retry_after. Opt-in paid broadcasts can raise the 30/s cap.
