Gestalt filtering. https://wordtothewise.com/2017/06/filtering-by-gestalt/ <https://wordtothewise.com/2017/06/filtering-by-gestalt/> In more modern filtering, particularly at Gmail, scoring is dynamic. There are still rules and they still assign scores. But the scores themselves can be modified by other scores in the process. It’s not a simple sum of scores so changing anything can change the overall status of a message. Take two identical messages and two IP addresses one with an arbitrary reputation of 5 and another with an arbitrary reputation of 10. By the score and sum method, the final email reputation scores would be message+5 and message+10. With relative scoring, though, the IP reputations might turn out to be 2 and 13. There’s also a big piece of individual filtering there - if you send from your account to your account with any sort of regularity, then that pattern will affect how mail from you, to you is delivered outside of whatever filtering there is. I’ve had to stop using my “main” gmail account for tests and go to a new one because Gmail figured out I regularly send from @wttw to @gmail and has prioritized that mail into the inbox. If I send to a different @gmail account, it goes to bulk. With the symptoms you describe, however, I’d look hard at the domain reputation. laura -- Having an Email Crisis? 800 823-9674 Laura Atkins Word to the Wise la...@wordtothewise.com (650) 437-0741 Email Delivery Blog: http://wordtothewise.com/blog
