I'm having the same issue. DS5's teacher even mentioned that email is the best way to reach her but then out of 4 emails she only responded once and that was couple days later. I don't need a lengthy reply. Just an acknowledgment that she got whatever I sent and if she has any input. A simple ok or thank you would be enough! When I have something really important, I put a note in DS's folder because I know the teacher checks it every day. She DID call me once as a response to my email because it required a more lengthy conversation so that was a nice change. But overall I'm not very happy with the communication but I wasn't expecting it to be anything too good given my experience with DSS who's now 20 and whose teachers back in middle school when we had issues always promised to keep me in the loop, regularly email me, blah blah blah and never did past the first week of our agreement.
