As you may have read in an earlier articles on MSL’s blog, direct mailings and printed advertisements have been shown to be the most effective marketing strategy, surpassing digital methods such as email. USPS wants to promote and bring awareness to the effectiveness of direct mailings, particularly when they are linked with online and digital media. QR codes give consumers the opportunity to actively and immediately participate in a marketing campaign or sales event.
