Your posting frequency depends on the topic of your channel. If you have a news channel, it’s OK to publish new content every day (or even every hour). For other industries, stick with 2-3 large posts a week. It’s easy to create a Telegram channel via desktop app or mobile app (for Android and iOS): The optimal dimension of the avatar on Telegram is 512px by 512px, and it’s recommended to use PNG format to deliver an unpixelated avatar. Users are more open to new information on workdays rather than weekends. 5Telegram Channel avatar size/dimensions
