I work with this exchange and I can say that there are many TG channels here for every taste and budget, which makes choosing and placing ads very convenient. With the publication planner, you can forget about daily manual searches. You just create a campaign, select channels, and set up the ad display – it automatically goes out every day on different channels for the entire duration. There's no need to communicate with administrators and discuss placement conditions. Everything is done in just a few clicks. The channels in the database are generally good, although there are some weak ones, but they are easy to spot by the statistics. I have never bought ads on bad channels, and the results have always been decent.
