Re: WTF?
I agree, even easier as there was no action required.
Hi [Name], We're writing to notify you that your account is among a number which *have* been involved in a security breach. Please log into your account using your normal route to see further information and what steps, if any, to take next. As always, please do not click on links on emails, we will never ask for your details..... blah blah
If a reset is required, deal with it when a log in is attempted, not using an email link. Unfortunately, marketing departments have ensured that 'legitimate' emails are full of full page banners and images, so people are not trained this way.
