Gmail Postmaster Tools: What You Need to Know Luke Martinez July 15, 2015 Best Practices // SUMMARIES ?> Our friends at Gmail recently announced Google’s new Postmaster Tools dashboard. (Thank you, Google!) Like the release of their Spam Feedback Loop a year ago, it eliminates a blind spot in the email ecosystem. It gives qualified high volume senders visibility into key metrics that help them improve the quality of their email campaigns and troubleshoot deliverability hiccups. SendGrid has been using Google’s Postmaster Tools for a while now and the data is incredibly valuable. It helps our delivery consulting team quickly identify root causes of deliverability difficulties, and our anti-spam team uses it to identify customers that sent unwanted mail. If you send a lot of email, sign up and learn about the health of your email programs, including: Delivery errors (volume of traffic rejected or temp-failed) Spam complaint rate as reported by Gmail users Authentication results (SPF, DKIM, and DMARC) IP reputation (high, medium, low, bad) Will this help me? If Gmail represents a large portion of your mailing list, Google’s Postmaster Tools could be invaluable, helping you learn, adapt and improve more quickly. How should I use it? Gmail has some of the most sophisticated email filtering and spam detection algorithms in the industry. Gmail often spots unwanted or untrusted mail quickly. Savvy senders will pay close attention to how their mail is performing at Gmail, and use these new signals to optimize their email program as a whole. Lessons they learn from observing their campaigns at Gmail will likely improve delivery results at other mailbox providers too.
