Email marketing is one of the most effective ways to increase the response rate of a postal direct mail campaign when used as a supplemental channel—not a replacement. Email reinforces the mailed message, improves recall, and provides a fast digital response path that complements physical mail.
Direct mail captures attention in a tangible, trusted format. Email extends that impact by keeping the offer visible in the inbox during the critical response window.
According to USPS research on integrated campaigns, combining physical mail with digital channels improves engagement and response compared to single-channel efforts.

In most campaigns, email is used as a coordinated reinforcement—not a standalone blast.
A typical direct mail email supplemental includes one to three emails delivered before, during, or shortly after the mail drop.
These emails mirror the core offer and call-to-action found in the mailed piece, ensuring consistency across channels.
