It's not just Google, sadly. We have a noticeable level of problems with big name mail services and major ISPs silently dropping messages, including messages we are legally required to send. This remains the case even though we're sending through reputable mail servers, SPF is set up, etc. The likes of Google and Microsoft have applied embrace-extend-extinguish to possibly the most important communications medium of modern terms, successfully making it less reliable than it has ever been for sending legitimate, actually important stuff. They really should be strongly and publicly criticised for that. False positives in spam detection are, for the most part, more damaging than false negatives.
