The postcards are quite a bit cheaper than the letters. 

I am looking for a company that provides:- No minimum quantity on letters and postcards;- Set it and forget it option (add mailing list to campaign that sends out monthly letters for a couple months and followed by monthly postcards)- Charged only when the letters/postcards go out (not charged for the whole campaign and products that will be sent in the future)Any suggestions?

I'm getting ready to start out, and I'm wondering about this.First of all, our REIA leader last night defined "campaign" as one specific day and marketing method (eg. pink postcards mailed on 5/1).

This can be as simple as Mailing out postcards, getting a website through Carrot and optimizing your website for search engines (this is called SEO).

Not a postcard.

Postcard is the way to go.I end up getting several deals every year from this method.

I use a combination of automated and hand addressed on post cards. 

"Life is not about money" is a great wall art, post card, catch phrase.   

Also, if anyone knows of a REI Database program such as the one that Than sells (only if you buy a bunch of his other junk) then that too would be awesome.Lastly, if anyone has some excellent and tested, full color, or Cris Chico style postcard "samples" they wouldn't mind sharing then that would be really neat!

-only send postcards.
