How scheduling Telegram posts works
Telegram channels reach your audience directly, with no algorithm in between. Tesselith posts to your channels through a bot you add once, and lets you send quieter updates without a notification.
Connect Telegram by adding a bot you create with BotFather as an admin of your channel. Write your post in the composer, tailor it for Telegram if you like, attach media, and pick a time. Tesselith queues it and publishes at the moment you chose, then reports back so you always know it landed.
