"Handwritten" computer fonts do not work, I have tried them.

The name is pre-filled and you simply pick the font you want to use. 

font?

One page, two at the most, 14 point font.

It's an insult to my intelligence, when they print these postcards with "...street" printed in a different color or font, showing that they have this blank formula and just instruct the computer to fill in that address.

Use an easy-to-read font.

I'm mailing in the Silicon Valley, a.k.a. the Bay Area in California where there are very little foreclosures and motivated sellers so our letters need to be tailored to people who just want to sell their homes without going through the drama of an open house.When ordering, I noticed a lot of different options like having an actual human write your addresses vs just using a handwritten font.

I get colored postcards which pretty much everyone I know thinks are a joke, form letters (always in neutral/white to camoflauge what they are I imagine) with my addresses or name in a different font so it looks amateurish, full letters with just my name written in ink,  ect. but super easy to spot whether they have a return address on the envelope or not. 

One word of cautious is if you aren't going to actually handwrite the letters, make sure the font you're using actually looks handwritten.
