Tracking Text Message Invites

I wanted to know if there is anyway to obtain records when a text message is sent to a client. I’m aware that you can see it in the sent box of your email, but there is no way to prove this via text. This is problematic in terms of clients who claim they never receive the text. More importantly if a client is not willing to share their email address and can be problematic. Clinicians need to be able to track when they send invites on all platforms not just calendar and email. Not all clients are comfortable with that and it’s uncomfortable as a clinician to not be able to have those communications. We should be able to see when we send those invites and to which number in order to provide proof that the invite was indeed sent.
