What services or platforms are there for organizing communication with customers via SMS?

Question

Marketing

Hello!
Please tell me, maybe someone knows such services?
It is necessary that customers can respond to you, and you can send them mailing lists. Mailings to 10-15 people at a time.
If you can make an alphabetic phone number - then it's generally super!
Thank you!

Answer 1

Why SMS? This is the last century. Use push notifications.
For example PushAll. According to our statistics, 50% of users receive notifications from a computer and another 20% from tablets. As a result, by sending only SMS, you remain in the minority.
Users are now more comfortable with notifications via the Internet, and they can respond in your crm after clicking on the notification.
