I can confirm that there are some big problems with Google spam filter. Even emails from Google G Suite support ended up marked as spam. That started happening like 4 months ago. We had a problem with following emails: - all emails from sns.amazonaws.com are in spam - all Stripe emails about "Suspected fraudulent payment on your Stripe account" are in spam They all say "Similar messages were used to steal people's personal information. Avoid clicking links, downloading attachments, or replying with personal information." Anyway, if you depend on G Suite email to receive important notifications from PayPal, Stripe, or Amazon you will need to monitor your spam folder. It seems like there are some keywords (invoice, payment - I really do not know.) which will trigger spam filter.
