58.6% of consumers worry registration means spam. But 79.3% would register more with a no-spam guarantee. The data shows a clear path to earning trust post-purchase.
Product registration rates are abysmal — 68% of consumers never register. But the University of Michigan's research on 522 consumers reveals that the barrier isn't apathy or complexity. It's trust.
The top reasons consumers don't register are revealing:
The pattern is consistent: consumers aren't opposed to registering. They've learned not to trust what happens after they do. Spam inboxes, data broker sales, and promotional blasts have poisoned the well. The good news: the solution is surprisingly simple.
Despite the trust deficit, the same research shows that consumers strongly want the benefits registration provides — they just need to believe those benefits will materialize without a spam consequence.
The hierarchy is clear: warranty simplification is what consumers want most. Registration serves as proof of purchase and speeds up warranty claims — when brands communicate that plainly and follow through on it, registration converts.
The same consumers who won't register will open a warranty email at 75%. Trust isn't the barrier — spam fear is.
Based on UMich, Registria, and Clyde research data
Here is perhaps the most actionable finding in the UMich study: when consumers were asked what would make them more likely to register, 79.3% said they would register more often if companies were prohibited from marketing to them after registration.
This is an enormous unlocked value. Brands that convert a privacy-first registration approach don't need regulation to change behavior — they just need a credible commitment:
The brands that are building high registration rates aren't spending on acquisition — they're spending on promise delivery. The 79.3% unlocking potential is the most valuable statistic in post-purchase marketing.
79.3% of consumers are waiting to be given a reason to trust. The no-spam commitment is that reason.
The Clyde research makes a striking distinction between types of post-purchase email. Warranty and registration confirmation emails achieve a 75% open rate. The average promotional email open rate is 21%. The same brand, the same subscriber, different context — a 3.5x performance gap.
Why do transactional emails win on trust metrics?
The implication for brand marketers: the post-registration email sequence is not a marketing channel. It's a trust channel. Treat it as such and the performance metrics take care of themselves.
No-spam commitment is prominent, not buried. The registration flow communicates exactly what data is collected and how it's used — before the consumer submits anything.
Immediate, genuinely transactional confirmation email. Registration simplified, warranty docs included, product resources linked — proving the privacy promise in the first touchpoint.
Post-registration emails are product tips, safety alerts, and recall notifications — never promotional blasts. The 75% open rate is earned by keeping every message genuinely useful.
