What DM+ Is
Direct Mail Plus (DM+) is an SLMP-delivered direct mail enhancement that transforms your campaign into a coordinated, multi-touch experience backed by real-time analytics.
It’s built for marketers who already believe in mail but want:
Better insight into performance
More opportunities to lift response
A smarter, measurable approach that keeps direct mail at the center
What DM+ Isn’t
DM+ isn’t a replacement for digital marketing, and it’s not a pivot for SLMP. We still offer direct mail campaigns without DM+’s digital tie-ins, but we don’t run digital efforts without mail. The digital elements of DM+ exist for two reasons:
1
To help your mail convert better
2
To help you see its role in overall performance
Mail stays at the heart of everything we do—DM+ just takes it further.
Think of DM+ as our love letter to direct mail—not our replacement for it. DM+ exists to support direct mail in being all that it can be by amplifying its impact and making the results easier to understand and act on.
DM+ in Action
We do direct mail really, really well—but historically, mail hasn’t always answered every question about who’s responding, what’s working, or where to focus next.
DM+ was built to bring fresh visibility to the areas of direct mail where insight has been limited—so you can finally see what’s working, replicate success with confidence, and make every campaign smarter.

What DM+ Delivers
DM+ At a Glance
