Writing a price-increase letter that doesn't spike your cancellation rate

Every pricing team eventually has to send a price-increase notice, and the difference between a well-executed one and a poorly-executed one shows up directly in the cancellation and downgrade rate over the following weeks. A few practices consistently separate the two outcomes.

Lead with the reason, briefly and specifically, rather than burying it. "We're raising prices to keep investing in X and Y" lands better than a generic reference to "market conditions," and it lands far better than no explanation at all — loss-aversion research suggests unexplained price increases get evaluated more harshly than ones with a clear, credible rationale attached, even when the rationale doesn't fully offset the cost to the customer.

Give real notice. 30 days is a reasonable floor for consumer subscriptions and considerably longer for B2B contracts with procurement cycles; several state laws and platform policies (app stores in particular) set minimum notice periods, and even where none is legally required, adequate notice reduces the "I feel ambushed" reaction that drives the sharpest cancellation spikes.

Segment the message where you can. A customer who has used your product heavily for two years and a trial user who signed up last week don't need the identical message — the loyal customer benefits from acknowledgment of their tenure and, where economically sensible, a longer grandfathering window or grace period, while a new customer mainly needs clarity before they commit further. And don't bury the actual new price: state it plainly, in the same channel and as prominently as the original signup price was shown, which is both good practice and, per the FTC's ongoing disclosure enforcement, an increasingly explicit expectation rather than just a nicety.
