Offer incentives for continuing
Sometimes, even loyal users want to leave. Don't let them go by offering attractive incentives that might make users reconsider their decision to cancel. It could be a temporary discount or a free upgrade to their current plan.
If you figure that users may have some financial issues, it's worth mentioning that they could opt to downgrade a subscription instead of canceling it entirely. Be friendly, polite, and don't pressure users to stay, no matter what. Your task is just to make sure they've considered all options.
