Material Change Notice
A material change notice is a formal communication from a loyalty programme to its members before it alters the earning, redemption, or qualification rules in a way that materially reduces the value of the programme. It is a compliance obligation in some jurisdictions, but its quality varies widely.
Loyalty programmes are built on a unilateral promise: the operator can change the terms at any time, and members usually have no remedy except to leave. The material change notice is the only formal checkpoint on that power, and in well regulated markets it is a legal requirement that forces the operator to tell members what is being taken away before it happens.
The industry uses the notice as a shield rather than a signal. Operators publish changes in low traffic footers, tie them to a 90 day lead time, and hope the member base does not read them. The result is that a devaluation goes live with formal compliance but zero actual consent, which is not what the rule was for.
The arithmetic of a bad notice is straightforward. A programme cuts its earn rate from 1 point per dollar to 0.8 points per dollar, a 20 percent reduction. A member who charges 10,000 dollars per year to the card loses 2,000 points on that spend, before any notice period has run. That lost earning is rarely converted into a cash figure in the notice, because the cash figure would make the change impossible to defend.
The three metrics that a material change notice most often resets are accrual, the active member rate, and activity-based qualification. A cut to accrual immediately slows the speed at which a member reaches a reward, a rise in the activity threshold removes the casual member from the active count, and a notice that buries that shift will show up months later as a silent fall in the active member rate. Operators treat the notice as a legal box to tick, but every one of these changes has a measurable retention cost.
The test of a genuine notice is simple. A member who reads only the first sentence of the email should be able to state what changed, by how much, and when. If the programme cannot write that sentence without hiding the number in a table of thirty other changes, it is not giving notice. It is managing the opt out rate.
