I have a small barbershop, and I tested Telegram, cautiously using geo-targeting. I started with 35,000 rubles and chose 3 channels in St. Petersburg — 3 people called and made appointments. I can't say it was a "wow effect," but for a test, the result is quite satisfactory. Therefore, I plan to continue the collaboration, and in the future, there will be even more clients. I recommend it!
