How do I send postcards in bulk without using individual stamps?

For large mailings, skip individual stamps by applying for a USPS Marketing Mail permit and printing permit imprints, also called indicia, directly on the cards. Presorting by ZIP code then unlocks the lowest rates.

• Get a permit: apply for a USPS Marketing Mail permit before your first bulk send.
• Use indicia: print the permit imprint in place of stamps.
• Meet the minimum: plan for at least 200 pieces per mailing.
• Presort: group by ZIP code to earn the best postage discounts.

This is the standard approach for mailing postcards at scale for marketing campaigns.
