What Size Postcard is Best?

The “best” postcard size, in strict ROI terms, requires testing campaigns to determine which provides you the highest return on your investment. In practice, testing is not always practical and/or “best” may be subjective, particularly if you have broad marketing objectives. This post shares what we’ve learned from years of both testing and anecdotal experience. Link to design formats.
