Constant Contact: Email & SMS

Constant Contact doesn't work with the shopify block if your email recipient is using outlook 365 I've been waiting since February for it to be fixed. The ability to use the shopify block is why I pay extra to constant contact but meanwhile I haven't been able to use for 8 months. Pretty embarrasing for a major email company to not find a way around this. Also, I'm still waiting for both shopify and constant contact to figure out a way to include collections as blocks as opposed to individual products. Do you know or care what your paying customers need?
