How Postalytics Calculates Costs
During the design and proofing process in the Postalytics Direct Mail Template Editor, the system will identify the format you’re using. If you add pages and want duplex printing, be sure to check “Double Sided” under the Settings tab. For more information on designing letters, refer to our help articles:

Then, when the proofed template is used in a campaign, the campaign wizard will calculate costs based on your account plan and the final proofed design:
One-sided, single-page letter: Charged as a “Simplex Letter”
Double-side, single page letter: Charged as a “Letter” (Duplex printing).
Print on backside, or additional pages: Charged as “Extra Page” based on a double-sided design and the number of pages in the proofed template.
See the example below showing the campaign wizard breakdown of charges for a campaign with a double-sided duplex letter.
