My therapist is pretty bad with email- I use it frequently because it works for me to write to him, but if I need a reply I text or phone him. He is trying to use one account for his clients, but I don't know how this is working out for him- I don't think he sees everything I send him (which is fine for the way I use it). I think it's still possible to miss things coming in even on a dedicated account.

Could you use text to just alert her that you have sent her an important email? It helps me to know that I can follow up another way if I am worried he'll miss something. And I know my therapist prefers that I reach out again to alert him to something rather than ruminate over why I haven't heard back.
