SMS mailing lists are the same advertising channel as contextual advertising, SMM and even billboards on the highway. This means that they are also integrated into the overall marketing strategy and promote the business.

We use SMS companies separately and in conjunction with other tools. For example, you can duplicate email newsletters - deliver information to customers that is important to read as soon as possible. If reminders about tax payment deadlines or flight departure time are lost in the mailbox, the customer may suffer and lose money. Therefore, it is correct to duplicate such letters by SMS.
