Here’s an email I received this evening:

Hello,

As we have just entered into a new year, we wanted to contact you on behalf of COMPANY to see if there is anything you would like to ask us or know more about.

Please feel free to email me with any COMPANY queries you may have and keep my details on file for any future features you may be planning.

Simple.  Friendly.  Useful.  Well written.  To the point.  Unobtrusive.  Well done!
