By the time you receive a email from SONY you will be already banned. (It will be about you being banned)
Back then when hacking was new they had emails sent saying they would forgive anyone who purged their systems of homebrew and updated to the current version (that was 2011 or so).
Edit: While their wording wasn't exactly what I typed, it is what they meant when they sent the emails. That was the only time they warned anyone before actually banning people.
So if you don't receive any email from them, just chill.
