#1: Was this article written by an LLM? The phrasing implies there's a high chance
#2: Is your company sending spam emails? I don't know how Gmail's system works, but I will mark any unsolicited email from businesses as spam. Perhaps Google uses that as a heuristic?
Yes, it was. Recent Claudes absolutely love to spam an endless stream of very short sentences like this.
Totally sounds like an LLM wrote it. Should have been two paragraphs instead of this verbose drivel.
Gmail has a system of reputation as you suggest. It is very likely that enough people marked their emails as spam, which the OOP could figure out on the postmaster dashboard if they were so inclined: https://postmaster.google.com/managedomains
It also goes the other way, if enough people click "not spam" and interact with your mails, your reputation gets better. I'm currently trying to do that with my personal email/domain - will probably take some time though. For now, my friends say my mails land in spam even though I get a 10/10 score on mail-tester.com and similar sites.
