I came a cross a website that offers a great service, it has an Official Notice generator that you can fill out then email to another party.
BureauOfCommunication.com has a mission as stated on their website.
Every day, there are millions of thoughts that go unspoken. To promote better understanding of the peoples of the world, the Bureau of Communication is pleased to present a fill-in-the-blank stationery for everyday correspondence. Whether you need to communicate a problem, send an invitation to an event, or simply apologize for a transgression, our easy-to-use forms will ensure that your message is clearly conveyed.
One mission when using this service is simple. Sending hate-mail has never been easier.
