What is a typical email marketing ROI for B2B businesses?

Email marketing consistently delivers one of the highest ROIs in digital marketing — industry estimates average $36–$42 return per $1 spent. For B2B, email nurturing sequences that educate prospects over weeks or months often drive the highest-value conversions. ROI varies significantly by list quality, segmentation, and automation sophistication — basic batch-and-blast campaigns underperform well-segmented behavioral sequences.
