Your next-step checklist
You haven't picked a decline reason, so the wording stays neutral.
- Open the payment in Stripe and find its decline code, then pick it here for tailored guidance.
- Check in Stripe whether a retry is scheduled before you mention one to the customer.
- Add a payment link if you have one, such as the hosted invoice page or your customer portal. Otherwise the email asks the customer to reply.
- Check what your Stripe Billing settings do if the invoice stays unpaid before telling the customer about any access change.
