Telegram is my favorite messenger for chatting. There are many reasons for this. But Telegram is also very suitable to use it as a notification service for your own projects. For example I get a daily overview of the number of page views of my blogs, but also notifications about new Webmentions, or likes and announcements via ActivityPub are sent to me via Telegram.
