Using SMS with Churnzero

Hi Everyone, 

I'm currently in the process of rolling out Churnzero and am looking to implement SMS into our digital experience as most of our customer base rarely reads emails or has time to pick up the phone.  Has anyone had experience integrating an omnichannel communication platform on top of Churnzero or other CSP to make this happen?

Currently looking into SFDC Digital Engagement but would like other ideas of there are good ones out there.

Thanks!!
