Latest / Marketing Automation with Fexingo: HubSpot, Marketo, and Automated Customer Journeys / How Marketing Automation Workflows Miss Credit Card Expiration
Transcript
- Lucas: Alright, let me pitch you a number. A SaaS company we work with — about five thousand subscribers, average revenue per user of forty dollars a month — was losing roughly eight thousand dollars a month to what they called 'mystery churn'. Luna: Mystery churn meaning customers who just disappeared without a cancellation? Lucas: Exactly. No cancel button clicked, no support ticket, no 'I'm leaving' email. They just stopped paying. And when the team dug into the billing logs, they found that over sixty percent of that churn was involuntary — triggered by a single event: the customer's credit card expired. Luna: So the card on file reached its expiration month, the recurring charge failed, and the workflow just... gave up? Lucas: Worse than gave up. It sent a generic 'payment failed' email — no context about why it failed — and then, after three retries over five days, it cancelled the subscription. No attempt to ask for a new card. No proactive outreach before the expiration hit. Luna: And this is happening because most marketing automation platforms don't natively track card expiration dates, right? They just process the transaction or don't. Lucas: Right. The platform knows whether a payment succeeded or failed, but it doesn't know why. So the automation treats a declined expiration the same as an insufficient-funds decline or a fraud block. And the recovery workflow is identical — which is usually a weak, one-size-fits-all email. Luna: So the fix is to add expiration date data into your CRM or customer database before the payment even happens? Lucas: Exactly. The company I mentioned added two custom fields to their customer object in HubSpot: 'card expiration month' and 'card expiration year'. That data came from their payment processor — Stripe in this case — via a nightly sync. Then they built a workflow that checks every day whether any active subscriber's expiration date is within the next thirty days. Luna: And when it finds one, it triggers an email? Lucas: A very specific email. Subject line: 'Your card on file is expiring soon.' Body: 'The Visa ending in 1234 expires next month. Please update your payment method to keep your subscription active.' With a direct link to a secure portal. No login required — just a tokenized URL. They also added a second trigger: on the actual expiration day, if the card hadn't been updated, they sent a text message reminder. Luna: And the result? Lucas: Twenty-two percent reduction in involuntary churn within two months. That's about seventeen hundred dollars a month recovered. And the total effort was a few hours of workflow configuration and one database sync. Luna: But I always hear the PCI compliance objection. Aren't you not supposed to store full card numbers or expiration dates? Lucas: That's the nuance. PCI DSS prohibits storing the full card number after authorization, but it explicitly allows storing the last four digits and the expiration date. So as long as you're not storing the full PAN — the primary account number — you're compliant. Most payment processors like Stripe or Braintree give you an API to retrieve the last four and the expiration. You just need to sync that into your marketing database. Luna: Okay, so the data is available. But I also wonder about timing. Is thirty days before expiration the right window? Lucas: It depends on your billing cycle. For monthly subscriptions, thirty days works because cards typically expire at the end of a month, and you have a full billing cycle to resolve it. But if you bill annually, you might want to start at sixty days, because the stakes are higher. The key is to avoid sending the email on the exact expiration day — that's the most common mistake. Luna: Because by then the card has already been declined? Lucas: Exactly. The expiration is valid through the last day of the month. So if your card expires in June, it works on June 30th — but on July 1st, it's dead. If you send a reminder email on July 1st, the customer is already locked out of their account, and you're playing catch-up. Much better to send a proactive email on June 1st, then a follow-up on June 15th, and maybe a text on June 28th. Luna: And what about retries after the card is updated? Do you automatically retry the payment, or do you wait for the next cycle? Lucas: You absolutely want to retry immediately — within an hour of the card update. Some platforms like Recurly or Chargebee do this automatically. But if you're using a simpler setup, you might need to build a webhook that listens for the 'payment method updated' event and then triggers a one-time retry. Otherwise, you're leaving money on the table for an entire month. Luna: There's also the suppression issue. If a customer updates their card via the customer portal, does your workflow know to remove them from the expiration campaign? Lucas: That's a huge one. If you don't build in a suppression rule, you'll send an embarrassing email to someone who already fixed it. The workflow needs to check the 'card expiration date' field every time it's about to send, and if the date has changed — or if the customer's status is now active — it should exit. We've seen companies send six follow-ups after the card was updated, and that creates a terrible experience. Luna: So the ideal workflow is: a daily check of expiration dates thirty days out, send a proactive email with a clear link, retry payment after update, suppress once updated, and follow up with a text on expiration day if no action. Lucas: That's the skeleton. You can add layers: segment by card type — Amex has different expiration rules than Visa — or by country, because some regions issue cards with longer validity. But even the basic version recovers fifteen to twenty percent of involuntary churn. Luna: You know, listening to this, I realize how many teams treat billing as an IT problem, not a marketing automation problem. But the communication around billing failures is pure marketing — it's retention messaging. Lucas: Absolutely. That's why this fits so naturally into our show. You're not changing the product. You're not changing the price. You're just making sure the customer knows they need to update a piece of plastic in their wallet. And that's a marketing job. Luna: I think a lot of listeners could implement this in a single afternoon. Lucas: Yeah, and that's the beauty of it. You don't need a new tool. You just need to connect the data you already own to the automation you already have. Luna: If these marketing conversations have sparked something you've actually used in your own work, and you want to keep the show ad‑free and independent, there's a simple way to support it. Lucas: Honestly, if today's episode was worth a coffee to you, that's the link — buy me a coffee dot com slash fexingo. No pressure, just a way to keep these deep dives coming. Luna: And we really appreciate it. It lets us spend time on the details that make a real difference. Lucas: Okay, back to the workflow. One more nuance I want to hit: what happens when the card is updated but the expiration date is still in the past? That sounds obvious, but I've seen a case where a customer entered a typo — typed '26' instead of '27' — and the workflow kept pestering them. Luna: So you need validation on the input side too. Lucas: Right. The portal should reject an expiration date that's in the past, or at least flag it. But beyond that, your workflow should check that the new expiration date is at least one month ahead. If it's not, send a confirmation email asking the customer to double-check. Luna: Another thing: what about virtual credit cards or temporary cards that some banks issue? Those often have expiration dates only a few months out. Lucas: That's a growing edge case. For those, you might want to send a reminder earlier — say, forty-five days out — because the window is tighter. But the core logic stays the same. The important thing is that you're not treating every payment failure as a mystery. Luna: And you're also not over‑emailing people whose cards are fine. Lucas: Exactly. A well‑built expiration workflow is actually a respect signal. You're saying, 'We know you want to stay subscribed. We're helping you avoid a disruption.' That builds trust. Luna: Alright, so to recap: add card expiration fields to your CRM, build a nightly check thirty days out, send proactive emails with a direct update link, retry payment immediately after update, suppress after success, and validate the new expiration date. Lucas: And if you want one takeaway from today: check your billing logs for 'declined due to expiration' codes. If that number is anything above zero, you have a revenue leak that a simple automation can fix. Most platforms track this — you just have to look.
