Honestly, I had higher expectations. In reality, it’s just bright promises, and in practice, it works like all the others. What disappointed me: first of all, there’s no guarantee that emails won’t end up in SPAM, despite the promises. Statistically, I noticed that many emails were never delivered. I won't even discuss the open rates, although maybe that’s my fault. Secondly, the sending through Viber works strangely. Ideally, if the messenger is installed on the client's phone, it should be used. I have acquaintances in my mailing list (for testing) who also receive this email. So, despite having the messenger, they received regular SMS instead. The positive aspects are primarily related to the free notifications. I thought it was just another promotional offer, but they really are free. Many people are falling for this now, so it can be used. Another advantage is access to terminal databases, which is useful for SMS mailings. This is important for those who don’t have their own database or want to expand it. There’s an option for targeting settings, and you can even specify neighborhoods and streets in cities. After the mailing, a detailed report is provided.
