However, I am also receiving lots of stuff from unknown sources - unsolicited email.
GDPR seems to be making things worse and not better if I have to cope with a deluge of spurious emails as a result of GDPR.
How difficult would it be for Google or Yahoo mail to deny access to my email unless I had first explicitly approved a request to send emails to my account?
There must be a way of filtering by prior approval or else things may get just out of hand?
