When headlines report an average 5% postal rate increase, non-profit boards and fundraising teams naturally worry. In the non-profit world, where budgets are tightly managed and every dollar raised counts toward a mission, there is an understandable knee-jerk reaction to reduce direct mail quantities to keep postage line items under control. However, cutting your donor list out of fear can cause far more harm to your end-of-year fundraising goals than the postage bump itself.

To see how the new rates impact real-world campaign budgets, we ran a direct comparison test. We took two actual non-profit appeals mailed earlier this year and processed the exact same mailing lists through the new USPS rate software:

• Mailing #1 (90K pieces): Original postage was $13,700. Under the new rate structure, postage came out to $13,972—an increase of just $272.
• Mailing #2 (186,000 pieces): Original postage was $28,525. Under the new rate structure, postage came out to $567 extra, totaling $29,092.

In both cases, the actual real-world increase was only 2%. Headline percentages reflect overall category averages across all mail types and entry points.

When a mailing list is well-maintained, properly presorted, and optimized for distribution, non-profits can retain significant postal discounts that keep rate changes far lower than the national average. Trimming 5% to 10% of your donor list to offset a modest 2% postage shift often eliminates your most responsive mid-tier or lapsed donors—costing thousands in missed contributions.

Before making cuts to your upcoming appeal quantities have your mailer run the list for actual postage due while still in the planning stage of your campaign. Knowing your exact numbers upfront ensures you make data-driven decisions that protect both your postage budget and your fundraising results.
