If reminding customers that they are actually making recurring payments to a company causes that company to go out of business, I don't think we need to shed any tears.
I meant what noir_lord said. Ira Glass' monthly donation to NPR got cancelled when Target breached, for example. You can probably back date such things, but a lot of people don't.
You mean "If requiring customers to go through the trouble of re-submitting all their payment information…", surely. Because what we're talking about here, not merely reminding them that they are paying.
