Direct marketing effectiveness by channel Email marketing — average ROI of 3,600-4,200%, the highest of any marketing channel. SMS marketing — open rates above 90% and click rates around 19%. Direct mail — response rates of 4-9% to existing customers, 1% to cold lists. Telemarketing — 8-10% conversion on warm leads, far lower on cold calls. Retargeting ads — 10x higher click-through than standard display ads. Definition: Direct marketing is highly effective when targeted properly, with email delivering the highest ROI of any marketing channel at 36:1 on average. Other channels like SMS, direct mail, and retargeting consistently outperform mass advertising in measurable conversion and cost per acquisition. The numbers look great in industry reports, but they hide one truth: effectiveness collapses when companies send irrelevant offers to people who didn't ask. The quality of the list and offer determines everything.
