Measure direct mail ROI with incremental lift testing: hold out 10-20% of your list, compare conversion rates between mailed and holdout groups over 4-6 weeks, and calculate incremental CPA and ROAS. Promo codes alone capture only 20-40% of mail-driven conversions.

Write direct mail copy by leading with the recipient's benefit, using specific numbers instead of clever wordplay, and following the PASTOR framework: Problem, Amplify, Story, Testimony, Offer, Response. End with one clear, prominent call to action.

Use direct mail when customer lifetime value exceeds $500, when audiences suffer email fatigue, for high-consideration purchases requiring trust, and for win-back campaigns targeting lapsed customers. Avoid it for low-LTV products or time-sensitive offers.

Letter packages typically achieve 3-6% response rates, dimensional mail reaches 5-15% for high-value targets, and postcards range from 1-5% depending on size. Format choice should match offer complexity, audience value, and budget.

USPS rejects or delays mail due to incorrect address block placement, wrong postage, barcode formatting errors, prohibited materials like metallic ink on addresses, and missing return addresses. Verify requirements with your mail house before designing and use CASS-certified addresses.
