First class vs Standard Mail Yellow Letter

[Bradley Smotherman]

I am working on my goals for 2015 and have decided that 2015 is my year to "go for broke". I have set aside about 30k for marketing by direct mail. 

I am curious the ROI difference on standard vs first class on yellow letters. When I look at yellowletters.com it looks like I would be able to do so many more letters by using standard mail

I can mail 40,250 pieces standard, or 32,400 pieces first class.....about a 7800 piece difference.
