Depending on the type of mail piece you chose, it might require us to fold the piece in order to meet automation regulations.
For example, all self-mailers, newsletters, *brochures and *letters
(*to be placed in envelopes) need to be correctly folded with a hard
edge (the fold itself) on the bottom and *left (*if more than half
or tri-folded). We currently perform the following folds: tri, half,
parallel, double parallel, french, roll, accordion and half then
tri. For more information about what final fold sizes will be check
