NEW: the ENVacard™

Customized direct mailings with low postage costs

Our new product ENVacard™ offers envelope producers another option to create new products for the mail stream from their existing blank fed and web fed W+D envelope machines. The ENVacard™ has the look and feel of a traditional postcard but with many new marketing features. What makes the ENVacard™ new and of interest to both producers and marketers:


  • The four-sided ENVacard™ offers the possibility to personally design your mailing while preventing all personal data from being seen as is the case with a two-sided traditional postcard.  The information only becomes visible when the receiver of the ENVacard opens the mailing.
  • The printed ENVacard™ product can be produced on most high-speed blank fed W+D envelope machine models like the 320, 326, 410 and 627 and include ALL special creative attributes like foil (through the patch applicator), perforations (through the flex die), and windowing in one single production workflow.
  • The ENVacard™ in the US, conforms to the special reduced postage rate classifications for first-class post cards (up to 4-1/4 x 6) and meets automation requirements for letter rates on cards larger than 4-1/4 x 6
  • ENVacard™ offers a wide range of design possibilities. The windows can be produced with transparent materials or metallized papers and with tear away perforations and creative shape cuts – all are possible for an ENVacard™ – even consider adding a NFC tag now that Apple has opened up their API’s (additional equipment modifications required – ask your W+D account representative). ENVacard™ is an excellent way to capture the receiver’s attention and provide optional recipient personalization inside and outside (known to boost response rates) while expanding the utility of the modern complete cut W+D folding machine.
  • The ENVacard™ with a 6 x 9-1/2 trailing edge poker chip shape was just approved by the USPS for automation rates as part of the USPS Pilot Program for trailing edge shapes – it is your choice whether to keep the copy as poker chips but the shape must be the same as the approval. In return for acceptance into the USPS Pilot Program, the mailer needs to inform the USPS of the date, quantity and location of the ENVacard™ mailing.
  • An ENVacard™ kit is available to make both the maximum First-Class Postcard size (4-1/4 x 6) and up to the maximum letter size (depending upon machine capability/configuration) of 6-1/8 x 11-1/2.


*Production of the ENVacard™ on high speed web equipment requires the investment in an extrusion gumming manifold going across the web or the addition of a rotary back flap gum box so that the top of the card can be effectively sealed together with the side edges.

How to Design and Submit a Shape Cut Envelope to get USPS Approval 

W+D proudly received the first USPS approval ruling for automation rates with its W+D “dice” shape (see InFocus November issue) on 12/9/16 as case #80320. To maximize your chance of similar approval, submit 5 initial samples (unstuffed) and 50 samples (stuffed and addressed with the IMb – intelligent mail bar code) to the USPS Pricing and Classification Service Center in New York, NY.


Remember in your design that:

  • The basic envelope must still have rectangular corners on all four sides wherein the top, lead and bottom edge are all straight and the trailing edge is straight at least within 1/8" of the corner (i.e. the shape cannot ever exceed the top or bottom height of the envelope)
  • The shape must be on the trailing edge of the envelope (i.e. to the left of the address window or address block). If you are addressing the window on the flap side, that is ok – your trailing edge would then move accordingly.
  • Both the envelope (as defined in #1) and the shape (defined in #2) must fall within the maximum height aspect ratio of 2.5 (unfortunately, you cannot use the shape as an extension in order to get a “square” envelope to be within the height aspect ratio in order to avoid the one ounce surcharge).
  • Be sure you are converting at least 50# paper and that the shape is comprised of the two sheets (front side seam and back panel) coming together within .040” of each other as the USPS wants to avoid risk of interlocking pieces and has a .007” minimum thickness constraint. 
  • Obey all additional postal regulations in the DMM including window positions and clearances.
  • Refer to the W+D #10 “dice” approval letter case #80320 as further reference for seeking approval along with your submission of 5 unstuffed samples and 50 stuffed/properly IMb addressed samples.

Tip: Keep 5 samples for yourself so you know exactly what the USPS Pricing and Classification Service Center received.
