My first experience with this service was unsuccessful. I registered, closed the instructions, and tried to figure out the platform, but in the end, I couldn't find the necessary features and temporarily abandoned the idea of mailing. After some time, I logged in again and, thanks to the instructions, was able to understand everything. Conclusion: it's best to familiarize yourself with the instructions first, and then you can have only positive emotions from using the mailing service. It's convenient to track leads, create subscriber groups, and generate links for them. I especially liked the segmentation and filtering of subscribers — it's very simple and convenient, and only those you want to send messages to will receive them. I recommend getting to know the service first before closing the site and putting it away in a drawer.
