When were these emails received?
I got an email address and first started signing up for accounts in late 2011. There has been a steady stream of privacy related emails sent to my inbox since that time.
You can see an extreme jump in the number of emails received in the last few months because GDPR becomes enforceable on May 25th, 2018.. Zooming in on just March 2018 to today, the end of May 2018, you can see the days when most of those emails were sent out.
Who is emailing me?
This also gives me a chance to review some services that I may have forgotten I have an account with.
