This is a spam template sent to a lot of email accounts designed as a scare tactic. It's fake. In two of my email accounts, I've been receiving these off and on for years, and one of those accounts is only ever accessed from a PC that has no camera.
You can safely leave them in your spam folder. Report as spam/phishing if your email provider supports it. Also use this as an opportunity to revisit passwords on old accounts and change them. When possible, also setup two-step authentication methods (linked to your cell or email address) for all sensitive accounts, especially financial.
