SMS Gateway: What Is It?

With the advent of free messaging apps, there were concerns about the fate of SMS marketing.

That’s one of the reason why an increasing number of companies are choosing to invest in this channel.

Naturally, it may not be simple to send large quantities of messages, but thanks to gateways—server infrastructures that run applications useful for sending SMS messages—it is possible to manage high data flows.

Gateways, therefore, can acquire information from the databases of any software, encode it, and connect to telecommunications operators worldwide with extreme rapidity. This allows for the mass and timely sending of various types of SMS messages.

There are numerous areas of use: from healthcare to finance, from travel to telecommunications. This allows for a high level of customer service to be offered. This makes it possible to offer a high level of customer service.

2-Way SMS messages, on the other hand, are bidirectional messages that allow users to send responses, fueling dialogue with the company, to the benefit of customer retention and experience. Specifically, 2-Way SMS messages are very effective in surveys and questionnaires, event invitations, promotions, reminders, or in all those cases where a response from the user is expected.

Among the many advantages of Bulk SMS messages is certainly the possibility of personalizing communications based on one’s audience and quickly analyzing the results obtained.
