Standard Mailings Requirements

To process your mailings using the Documatch or W790 Address Machine, you must provide the following:

  • Address file in Excel Spreadsheet or CSV format
  • Good quality #10 envelopes (traditional or conventional flap only)
  • When using large envelopes, use gummed booklet envelopes
  • Use envelopes with flap lengthwise
  • When using large envelopes such as 8 ½ x 11 for the address printer, have the return address preprinted in the upper left hand corner – the address printer is unable to print a return address due to the size of the envelope.
  • Business Reply Envelopes (when applicable) with department return address stamped in upper left corner.

Note: On large mailings, we cannot accept:

  • #9 envelopes
  • Old envelopes (bowed, creased, watermarked, etc.)
  • Large, clasped envelopes
