Case 08 / FEDEX / Survey study · Max Diff analysis
Conversion Catalysts preference study
FedEx wanted to know which messages made prospects more likely to open an account. We surveyed 508 prospects in five regions, split evenly between personal and business shippers, and tested 30 value-proposition buckets with Max Diff. TURF analysis found the smallest message set with the broadest reach. Reliability and data security beat the discount-led copy the funnel relied on.

Prospect preference research across five global regions

Global prospect preference study
04 / Direction
Reliability is the single strongest conversion driver
On-time, reliable delivery ranked as the most preferred USP across every region and both segments. It is the one message that holds globally and should anchor the top of the registration funnel.
05 / Impact
Reliability and data security gave the registration funnel a stronger lead than discounts.
The preference ranking gave acquisition and product marketing a basis for rewriting the funnel. Reliability and security led, followed by free accounts, competitive rates, and fast delivery.
Case study details
Methodology
Phase 01
weight 2
Scoping
Defined target prospect segments (personal and business shippers), regions (US / CA, LATAM, Europe, MEISA, APAC), and the 30 USP buckets to test across the registration funnel.
Phase 02
weight 2
Instrument build
Designed a Max Diff survey instrument that could isolate which USPs moved prospects toward registration, controlling for region and segment effects.
Phase 03
weight 3
Fielding
Recruited and surveyed 508 prospects across five regions. N=254 personal shippers, N=254 business shippers, balanced for regional coverage.
Phase 04
weight 3
Analysis
Max Diff analysis across Feature Count, Average Feature Utility, and Preference Share. TURF analysis on message combinations to find the smallest set of messages that reaches the broadest audience.
Phase 05
weight 2
Synthesis
Translated preference data into messaging recommendations for the registration funnel and for acquisition channels beyond it.
Findings / 5
01
Reliability is the single strongest conversion driver
On-time, reliable delivery ranked as the most preferred USP across every region and both segments. It is the one message that holds globally and should anchor the top of the registration funnel.
02
Data security is a top-tier acquisition cue, not a footer
Data security and privacy ranked in the top preference cluster alongside delivery performance. Treating it as compliance language undersells its pull at the moment of registration.
03
Free account and competitive rates sit in the top cluster
Free account, competitive shipping rates, and fast delivery round out the top-five USPs. Together they form the practical-value core of the messaging stack.
04
Future-facing and accessibility-only copy under-performs
Future-facing framing and accessibility-only messaging ranked near the bottom of stated preference. Neither worked well as the primary acquisition message.
05
Messaging should diversify beyond discount-led copy
Prospects convert on a blend of reliability, security, and practical fit. Discount-heavy acquisition creative leaves the strongest preference signals underused.
