Heck a small yellow or pink Post Card can do wonders for prospecting in large numbers.

Red, blue and pink.

Its about getting them to open it..if there motivated, it wont matter if its pink,orage, blue, green they will call..Just my experience

Oh, and I ordered a batch of pink envelopes to send my letters in.

Make sure that next time you send an orange or pink card not yellow.  

BUT that is not all.. eye catching BUT not look like a generic random spam mailer.If mailers have been yellow for centuries and you are the first to send pink mailers, sure they will be noticed and read.But today?

At the end of the six months I would rerun the list and start over.Here are the six pieces of mail.1 Yellow Letter Tabbed (no envelope)2 Small PC Can be Yellow or twice a year Pink 3 - Yellow Letter in window envelope4 - Large PC Always Yellow5- Typed Letter Window Envelope6 - Zip Letter Michael, what are you seeing as average response rates with this series? 

But this site has yello letters, small postcards, large postcards, postcards with tear-away business cards, etc. using different colors for postcards can get people's attention too, like a pink postcard.You can even design your own letter or postcards to have them mail them out for you.

When you confirm that you dont , with intent, do anything illegal in any sense no matter how small it may be then I will concede that my "Holier than thou" comment doesn't apply to you.They are bandit signs for chrissake...not kilo's of cocaine.

I did them in pink.
