How do I remove my existing pro account? I don’t want my cc charged next month. So please get back to me before the end of the month.
If you go to the settings in mailspring, you have a tab “Subscription”. There you should be able to go to the mailspring subscription page to cancel it.
I hope, this helps.
I see you’ve got the real answer. When less reputable companies make it harder to do, I change my billing information to a valid Visa/MasterCard gift card so that any small charge verifications work, and then drain the card grocery shopping before the next billing cycle so the payment bounces.
