This article is braindead. They should have hired a technical editor. 1. Not every campaign is using the same back-end. So you cant compare emails from X to Y. 2. No technical analysis of headers, SPF, DKIM, DMARC 3. No keyword analysis or word frequency analysis on the content of the messages sent. I love how gmail sorts my email. I rarely have it send things to the wrong folder. I also don't want political spam in my primary inbox. Even if I sign up for it.
