Definition
Multi-touch attribution models divide conversion credit among all the email campaigns a subscriber engaged with before converting. Common models include linear (equal credit), time-decay (more credit to recent touches), U-shaped (40% to first touch, 20% to middle, 40% to last touch), and custom weighting.
Why It Matters
Most email marketing platforms default to last-touch attribution, which overvalues the final email and undervalues the nurture sequence that built the relationship. Multi-touch attribution gives a fairer picture of campaign performance, especially for long consideration cycles common in B2B and high-ticket ecommerce.
Implementation
True multi-touch attribution requires a cross-platform tracking setup — usually a combination of email platform data, UTM parameters, and analytics tools like Google Analytics, or a dedicated attribution platform.
