Ask HN: For help: Gmail is filtering our URLs

The gmail.com client normally renders the hyperlinks in our outgoing email just fine. Yesterday morning, this suddenly stopped happening and users were sent links that could not be clicked in their transactional emails from us. I was able to reproduce it by simply including our domain name in an e-mail, which leads me to believe e-mails are being filtered for our domain name specifically. I've reproduced this across multiple Gmail accounts of ours, and all hyperlinking is always fine right until I include our domain name anywhere in an e-mail. Viewing page source shows that gmail.com is employing some HTML to break our URL up so it doesn't turn into a valid hyperlink.

I suspect this is some sort of anti-spam measure. Has anybody else experienced this? I am asking Hacker News for help because there doesn't appear to be any way to get in contact with Google regarding gmail problems. We've already employed everything in their FAQs about avoiding their spam filters. We use DKIM and have a healthy standing with all email blacklists. I'm really not sure what other options we have left.
