Thank you. We're on the same page wrt emailing us to cancel. A quarter of our churn is actually users who have their cc declined and do not fix it, despite nag emails, in two weeks. I don't think we've ever heard back from a single one of these users. For the other 75% I guess we should just be asking more questions before servicing their request.
Hey, I used to run a SaaS product that solved the failed payment problem very specifically (http://churnbuster.io) and I'd recommend you extend that 2 week period out to something like 4 to 6 weeks. Some of our most successful customers were sending out 7-8 emails over a 6 week period. Every business is different, so YMMV, but it might help. A bunch of other thoughts on the subject that may be helpful to you here: https://www.quora.com/What-are-the-industry-average-rates-fo... .
While we're throwing out ways to solve CC declines with other solutions, Baremetrics actually has this very thing built in. :) https://baremetrics.com/dunning
