Assignment C5 (Wedding & Event Planning)

[S.Wiggles]

I'm a little confused by the direct mail assignment. I'm not sure what they're asking me to create. For starters, I can't seem to find the definition of direct mail on the pages of the "Marketing and Promotion" book like they mentioned. They also mention a letter of under 200 words in the assignment description itself, so are they just looking for me to provide text? or should I be designing something like a large postcard, which they also mention as a promotion material in the "Marketing and Promotion" book? Any guidance or suggestions, or even examples of what has earned a decent mark for others, would be great! Thank you in advance!
