Gmail has Postmaster tools that let domains with moderately large mail flow be able to monitor their spam reputation scores, email authentication e.g DKIM / SPF, DMARC rejection rates, etc. This tool can help address a number issues folks here have mentioned wrt Gmail. In particular please look at the "Delivery Errors Dashboard" description in the help center article. help center post: https://goo.gl/7QHoqc https://goo.gl/7QHoqc Postmaster tool: https://gmail.com/postmaster/ https://gmail.com/postmaster/ (disclosure I work in Gmail)

What about for the small time, personal servers? How do we get our mail delivered without having to use a third party service like Mandrill? I'm not blaming you personally, but the way Gmail handles email originating from personal servers is reprehensible.

We are using Gmail Postmaster tools (I work at a small ESP), and while this tool is certainly useful for diagnosing rejections, delivery to Gmail inbox / promotions is still a black box. In our case, a number of IP addresses we are using started showing up as "bad" in Postmaster tools, despite having no increase in complaint rates (actually, in Spam rate dashboard it shows 0.0% for the past 90 days). We have implemented Gmail feedback loop headers into outgoing emails to diagnose the issue, but the Feedback Loop dashboard also does not show any data. All of these IPs have a Senderscore reputation in the high 90s and deliver perfectly fine to all ISPs, except Gmail. Contacting Gmail team through their form also yields no response. My takeaway from this situation is that once Gmail starts not liking your emails for some obscure reason, you have practically no way to fix that, apart from getting a new IP / sending domain and starting to build sending reputation from scratch.

It's not a solution for low-traffic personal email servers. I've tested 3 domains in Postmaster Tools and for all 3 there's no data (I've added them a month ago or so - there should be data already) No data to display at this time. Please come back later. Postmaster Tools requires that your domain satisfies certain conditions before data is visible for this chart. Refer to the help page for more details.
