My cards meet the minimum / maximum size. They fall somewhere in between. Anything else to consider? I'm applying stamps myself. I'm not sure this qualifies as presorted or bulk mail. I just hoping something doesn't come up. I already had to redesign my cards because of the size. I'm using address labels to make things go a little quicker. A lot faster than writing the addresses by hand. I hope that doesn't turn into a problem with the placement of the label.
