The first impulse is to bulk delete and curse the clown who did this to you.
Curse away, yes, but comb through those emails with a gimlet eye to what actually may be important. Someone has done something underhanded and is relying on the flood of spam to bury an important notification.
Something where you really want to know: a Paypal transaction you didn’t authorize. A credit card transaction for something you didn’t buy and will never see. A notice that someone has applied for Covid-19 benefits in your name.
That last happened up in Canada to an acquaintance, who fortunately spotted the email in the heap of trash and is now recovering the account and unwinding the changes in their CRA account.
That so easily could have gone undetected.
