Why Attribution Models Disagree
First-touch credits the first email a subscriber ever received. Last-touch credits the final email before purchase. Linear splits credit evenly across every touch. Each tells a different story about your funnel — and a 20-point swing in attributed revenue is common.
High sensitivity is a warning sign. If your reported email ROI depends heavily on the model you pick, then budget decisions built on that number are fragile. Run this comparison before making spend decisions, and report attribution as a range rather than a single figure.
Deeper context: Email marketing attribution is mostly guesswork.
