Why SMS marketing doesn't disturb people?

The most essential thing is: SMS can't be sent indiscriminately, and the people you want to send must be users who have potential demand for your products or services. Information that is helpful to customers is naturally not annoying.

Late at night, busy with work, it's easy to be annoying.

The transmission frequency should not be too high or too low once a week.

Adjust the content to be sent every time, and don't let customers lose their freshness ~

I hope it helps you, haha
