There are several ways to get Telegram channel statistics. Telegram itself provides basic built-in stats — total subscribers, views per post, and reach — available to channel admins directly in the app. However, built-in stats are limited and don't show who exactly joined or left, how long subscribers stayed, or which invite link brought them.
For deeper Telegram channel analytics, you can use Telechurn. Add it to your channel as an administrator, and it starts collecting detailed telegram channel stats automatically — subscriber changes, invite link performance, churn rate, and audience segments. All data is available in the Telegram mini app, or in a full web dashboard.
