What kind of weird gmail spam, no my address, or google address?

Question

gmail

Good day guys, for
almost 2 weeks I have been catching a bunch of strange / identical letters in the spam section of the standard mac os email client. Collects 4 different gmail accounts, unsubscribed from everything that is possible.
Often the recipient is [email protected] ( how so? )
More often the recipient is my account that I use for a long time for google analytics, I regularly change the password. It also has chrome on it.
Frequency from 4 to 20 letters per day, filtered out more than a dozen addresses, and yet zero sense. Where does it come from?
What can be done?
More in screenshots.

Thank you!

Your box is inserted into bcc.
Where they got it from is a much more complicated question.
