Post Card Tips
When designing and planning a postcard run, here are a few things to think about:
A standard size postcard is 4.25 x 6. You should mail this card using a first class stamp or first class permit because it will be the least expensive rate - .21 per piece. Larger postcards (anything bigger than 4.25 x 6) are not eligible for the postcard rate - and should be mailed using the presorted standard mail rate.
