This SMS broadcasting service can be considered one of the pioneers in the field. It offers the ability to send messages to both landline numbers and worldwide. The functionality of the SMS broadcasts includes almost everything necessary. Using the service is very simple: just select a number or email, write the message text, and set up the sending. When filling in subscriber information, it is recommended to provide backup communication channels so that a duplicate message can be sent if the primary channel becomes unavailable. This could be another phone number or email. Prices vary depending on many factors, such as the subscriber's country, delivery type, and the number of sends per month. For me, the cost is about 1.5-2.15 rubles per message. It's hard to name an exact figure since the pricing structure is extensive and depends on many criteria. Payment for services can be made in various ways, from cards to electronic wallets. I use a card, and I haven't had any issues with extra charges. In the personal account, you can check all the information on sent messages. I haven't noticed any problems with the service's operation; it has been functioning for over 10 years and is a leader in the Russian market. Moreover, it does not inflate prices, and its use is truly beneficial.
