In reply to Carl Hancock.

If that's the case, I suggest it'd be a good idea for plugin devs to get up to speed with the CASL legislation in Canada.

While it allows for transactional emails, it doesn't allow for marketing components in that email. I didn't see the email that went out, as I don't use Yoast (or their GA plugin) but, given how forceful Syed is with the rest of his stuff, it wouldn't surprise me if there was marketing messaging in there.
