There are several places a coverage offer can live: an email three days after delivery, a registration card in the box, a winback campaign, or the checkout itself. They are not interchangeable, and the difference is not about squeezing conversion. It is about when the decision actually makes sense to the customer.
At checkout, the risk is already on their mind
A customer buying a $1,300 laptop is, in that exact moment, thinking about the $1,300. The question "what happens if this breaks" is live and concrete. A coverage offer here answers a question the customer is already asking. The same offer in an email a week later interrupts someone who has moved on, and asks them to re-open a purchase decision they consider finished.
Coverage gaps are a timing problem
Plans added at checkout start with the product. Accidental damage protection typically applies from day one, alongside the manufacturer warranty (they cover different things). Offers made later have to handle eligibility windows and the awkward question of what happened to the product in between. Checkout removes the gap entirely: one transaction, one receipt, coverage aligned to ownership from the first day.
One decision, not a campaign
Post-purchase coverage programs are an operations project: segmented emails, send timing, exclusion lists, unsubscribes. A checkout offer is a product decision made once. For the customer it is one tap on an order they are already placing; for the store it is a line in checkout that requires no ongoing marketing effort to keep working.
The decision is easiest right here
An offer at the natural decision point, priced against the product on the screen, is easy to evaluate and easy to decline. All the context a customer needs is already in front of them, so the decision takes seconds either way. Offers made later start from behind: they have to win back attention and rebuild that context before they can make the case. Urgency tools like a limited post-purchase window have their place in closing that gap, but they are working to recreate a moment that checkout gets for free. The strongest version of the offer is the one that arrives while the question is still open.
