I'm thinking that would get awfully time-consuming, awfully fast for that therapist. Just using the example provided, that's $5 per email, and you figure it's at least 10 minutes to figure out, type and send a BRIEF coherent response...that's $.50 per minute, or $30/hour at most. Not that Ts do this solely for the money, but they do have bills to pay, and I don't see that working well for too many of them. Never mind the boundary problems--my T would flip at the idea of substantive emails between sessions! He really emphasizes learning how to cope using a range of supports outside T. But I know, everyone's different, clients and Ts alike. Just my $.02.
