getting way more spam than normal last week - only with one email.

Can you clarify what you mean by "only from one email"?  Spam tends to run in cycles.  You should find these of interest-----------------------

OK.  That just means only the one account is on one or more spammer's lists.  Are the messages going to the Inbox, or are they in the Spam folder?

Inbox - I just raised the level in Outlook Junk mail and see what that does.  Something triggered it recently - must have been something I signed up for

I also got a notice of a delivery that uses same email for online autoparts store - but send and billing address where not correct but in my state.   No fraud on my card.  They even sent me a notice of delivery.

still get a ton of spam
