Step-by-step instructions
In the Automation workflow, Click the trigger to check it — it's already set to fire when a subscription payment fails. Nothing to change here.
Open the Notify Owner step and check the internal notification is addressed to you (or whoever manages your payments).
Open the email to your client and personalise it. Keep the tone warm and blame-free — a simple note that the payment didn't go through, with a clear way to update their card details.
Save and publish the workflow.
⚠️ A failed payment is almost never intentional — most are expired cards. A kind, matter-of-fact email keeps the relationship intact and gets things sorted fastest.
