To name and shame two: LinkedIn and MyHeritage. If you ever made an account with either of them, they will never stop spamming you. They have configuration options to select which mail to receive, but they appear to consider them temporary suggestions.
A special dishonourable mention goes to Wal-mart. I never interacted with them in any way whatsoever, as well I wouldn't since they don't exist on my continent as far as I know, yet they still send me spam. DKIM signed and all!
LinkedIn once seemed to somehow go through my (GMail?) contacts and ask if I should invite my, late, grandfather to the platform in the subject of a marketing message.
Left a bitter taste.
