I focused on increasing the number of subscribers and automatic message sending. At the moment, I can track and evaluate the growth of subscribers. I haven't used the mailing feature yet, just explored its possibilities. I think that after a month of active use, I will be able to understand the functionality better. So far, my impressions are positive. However, there is still a lot to learn to understand how to act correctly, and of course, to test all the available features. There are indeed many useful options here.
