What is the average response rate for direct mail postcards?

Postcards are one of the strongest direct mail formats, typically generating response rates around 4 to 5 percent for house lists. Their edge is instant visibility, since there is no envelope to open before your message is seen.

• House lists: roughly 4 to 5 percent response is common.
• Instant read: no envelope means the offer is visible the moment the card is picked up.
• Bigger cards: oversized formats like 6 x 9 tend to outperform standard 4 x 6 because they are harder to overlook.
