Email template or Hint template (/backslash-phrase) that autofills fields from the patient's membership. For example:

Hi [Patient Name],

Thank you for letting us know — we completely understand.

Before you go — if it would make a difference, we can hold your membership at 30 percent off for the next three months. That's $[DISCOUNT PRICE]/month for [DATE], [DATE], and [DATE], returning to $[FULL PRICE]/month on [DATE]. Just reply and we'll take care of it.

If the discount doesn't change things, that's completely okay too. Your membership will end at midnight on [DATE], with no additional charges after that. If you're ever ready to come back, just say the word — re-enrollment carries a $100 fee and placement on any wait list we have at the time, but the door stays open.
