Overview

Our handwritten postcards combine authentic pen-written messages with real stamps for a personal, eye-catching mailer that stands out in the mailbox. Unlike printed postcards, every message is written using your selected handwriting style, giving it a human touch that boosts open and response rates.

Handwritten postcards are USPS-compliant and printed on durable 100# card stock, making them ideal for outreach campaigns where personalization drives results.

Typical Use Cases

  • Thank You Notes – Express gratitude to customers with a short, personal message.
  • Follow-Ups – Nudge leads who haven’t converted with a handwritten reminder.
  • Review Requests – Ask satisfied customers to leave a review in a genuine way.
  • Special Offers – Pair a personal message with a discount code to re-engage lapsed buyers.
  • Service Reminders – Perfect for home services companies reminding customers of seasonal maintenance.
