To be effective, a direct mailing also needs to "stand out of the mailbox”.
This does not necessarily mean it has to be large in format. To the contrary – an undersized envelope, especially when it has a personal touch, will accomplish the same result.
W+D has developed a small envelope kit for its W+D BB700 that will allow envelopes as small as 98 x 140 mm or 3 7/8 x 5 ½” to be processed. Such envelopes with a baronial or diamond shaped flap with the address printed with the right front and possibly even with a true stamp affixed will immediately stand out, be appreciated and most importantly be opened.
