Seems a couple hosts have blocked our emails. Some angry people reported us as spam or something I bet.
Does anyone have experience in getting this unblocked?

Are you getting any bounces on the sending mail server for the outgoing mail? Those help to troubleshoot, but if you're getting silently dropped by the receiving end, that makes it harder.
Last time I was dealing with getting mail dropped by an ISP (Comcast) it was an issue of they wanted a reverse DNS entry that matched the hostname of the outbound mail server for them to accept it. But that's dependent on where you're hosting from. Some cloud providers like AWS want you to use (and pay for) their mail services, and not send email out directly to reduce the amount of real spam coming out from their services.
What did you try changing? Did the error messages change at all?I have attempted to fix the issues but nothing seems to change.
