I'm really sorry that we do not offer email support at this time. We do however offer support in many other ways, such as calling in, using our chat support, or asking here in the community! Having email support is a great idea, I'll check and see if we have a feature request on that to track this for you.
Were you able to get your question resolved through chat? I see in your account that there was a recent chat discussing unsubscribes and how to get them resubscribed, looks like your question was resolved but if not please let us know, we're always happy to help.
