Random procharger question

Nothing critical, just wondering if anyone on here happens to have an email address handy for ATI/Procharger? I've been trying to get in touch with them, but having issues. I'm mainly trying to get some info on a mystery head unit on the Vette that has one of their serial numbers on it, but nothing else. I can't locate an email address on their website, they just have a page where you fill everything out and they contact you, but it keeps failing to send the info. I'm not sure if the problem is on their end or mine, I think I keep getting a bad gateway error or something. Obviously I could call, but a.) I prefer email, and b.) with my schedule, by the time I'm free and/or remember to call, they're already closed for the day. If anyone's got it, I'd appreciate it. Thank you.
