Here's a breakdown of the road-tested marketing tactics that have helped me accelerate our growth and shorten the sales cycle. And the research backs me up here — studies show that integrated direct mail and digital campaigns elicit 39% more attention than single-media digital campaigns. Professional marketers are in lockstep on this: 91% believe integrating direct mail and digital has a positive impact on campaign performance. The facts also don't lie; research confirms that direct mail has a much higher open rate of 90%. Another direct mail advantage: less competition in the mailbox versus the inbox.
