But for yellow letters they usually run $1.10 to $1.25 each including stamp, and for a list of 500, that can get costly very very quickly after 3-8 times.For absentee owner phone numbers, I have a software dev that uses a scraping tool on the tax assessor's website to scrape absentee phone numbers.

If you email [email protected] and let them know the cheapest price you are getting right now for yellow letters and that you want a quote beating the price you have (printed, folded, stuffed, and stamped) they will beat anyone’s price regardless of what their website pricing shows.

I'm using first class stamps.

For 291 .37 cent stamps came to $98.94.  

It's more about having a unique and effective mailer (e.g. envelope, stamp, color ink, font, message content), while also being consistent in your mailings (e.g. once a month for six months). 

I have a permit and already bought the pre cancelled stamps so I have part of the postage already covered.Is there a way you can private message me or something?  

I forgot to mention that if your using a Standard Stamp then you are required to use a return address or Indicia.

You know what i've found to help "distract" from custom fonts and helps them look more hand written...putting some sort of decorative stamp or sticker in the lower left corner.  

I've been using a spider man stamp. 

Before the Pre foreclosure business in WA and OR basically became illegal ( still legal in a very controlled environment) I would walk into a home I bought and many times the owner had left a stack of the letters they had gotten through the Foreclosure process I would venture to guess in our market if you had a NOD you got anywhere from 20 to 50 direct mail pieces and in those days the message on the direct mail peice was:"Hey I have been there 3 years ago I went broke had no money was living on food stamps I know how your feeling but I bounced back and if I can just help you with your situation Blah blah blah  same message 20 different ways.not sure how many phone calls.
