Worse: Gmail is labeling as spam emails that aren't. I send out email newsletters for my HOA using MailChimp and about 10% of the recipients (all Gmail users) never see the emails in their inbox. I've started texting them when there's a new email; half of them find it in their spam folder, half can't find it at all (and I see confirmation from the MailChimp side that the email was sent and did not result in an NDR).
