If Your Gmail Inbox Is Being Flooded With Promo Emails, You're Not Alone (buzzfeednews.com)
Gmail users are reporting that promotional emails (meant to showcase deals, offers, and other marketing emails) from companies are ending up in their main "Primary" inbox (meant for person-to-person conversations and messages that don't appear in other tabs.). The company says it is working on a fix. From a report: Google told BuzzFeed News it's working on a fix, but it did not specify when users should expect inboxes to go back to normal. In a statement, a spokesperson said, "We are aware of an issue in Gmail causing certain promotional email to be incorrectly categorized. We are rolling out a fix shortly."
If your mailbox is full of ads, maybe you shouldn't have an ad company run your mailserver.
I han't checked my gmail in years. Probably best I keep it that way.
Amazon never sent me spam or any other email that is not related to my purchase. Maybe you should check your mail preferences? I use Amazon for number of years and had prime membership for at least 3.
