Business relationship so you should be good.So your telling me a client you've had for 10 yrs you can't text unless they opted in ? I'd say 99% of agents don't adhere to these rules . I get 5 unsolicited tests a day . I know why know one answers there phone . I get 20 spoof # calls a day with the same first 3 digits .
Unless your client hates you, then it's never advisable.
