I liked the ease of use; everything is accessible and there are instructions. The support is top-notch; one night they helped me resolve an error in the funnel. I recommend it; I've been using it for about a year now, and during this time there have been many updates, which is also great. You can work in VK, Telegram, Viber, Instagram, and WhatsApp. I create funnels and mailings in Telegram. They added voice messages, videos, and formatting. The mailings work much faster compared to other services. There is no statistics for Telegram, but that's a problem with the platform itself, so I don't consider it a downside for the service.
