I didn't find any serious drawbacks. Minor issues, like getting caught in spam, aren't worth mentioning; they are present in all similar services. However, there are many positive aspects. The service interface is very user-friendly and intuitive, requiring no hints. The option for free usage is also supported. There are both push and email newsletters. The former are always free, while the latter are free until the subscriber base exceeds 200. For me, this lasted a month, after which I had to start paying as new clients came in. But it's clear that email marketing continues to work. The databases are checked for spam traps, and harmful addresses are filtered out. You can also set up automation so that emails are automatically sent to new clients when they are added to the database. The email editor is executed beautifully. You can create a nice email that will be adapted for mobile devices, tablets, and monitors. I checked, and indeed, the designs are responsive and display correctly. I'm satisfied with the price of the service; I've encountered cheaper alternatives, but their quality is significantly worse. I don't see any point in considering more expensive options, as they don't offer anything new.
