Hi there,

Please remove all data pertaining to myself or Happy Bear Software from your systems and refrain from contacting me again. Any future correspondence including a reply to this email will be reported as spam.

Kind Regards,

Honestly, a developer who's taken a flick through a book about sales and marketing (e.g. Ultimate Sales Machine) would do a fantastically better job of selling recruitment services (at both ends) than 99.99% of recruiters.
