5Telegram Channel avatar size/dimensions The visual aspect of channels is very critical. In fact, design is the first thing that a potential subscriber pays attention to, even though unconsciously. 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. Users are more open to new information on workdays rather than weekends. Don’t publish new content at nighttime. Since not all users disable notifications for the night, you risk inadvertently disturbing them.
