You send a promotional email to 500 subscribers. Open rate is strong. Click rate looks normal. Everything looks like it's working. But the payment link in that email? It died three weeks ago when you regenerated your Stripe link and forgot to update the email template. Those 500 people clicked. None of them bought. You'll never know unless you click the link yourself.
How Payment Links Go Silent
Payment links break quietly because there's no error message. The link still exists in your email. It still looks clickable. But when a customer lands on it, they either see an expired page, a 404, or a redirect to a dead product listing. Your email platform has no way to know. Stripe doesn't send you a failure alert. Your CRM doesn't flag it. The customer bounces. You lose the sale and never see it in your analytics.
This happens because payment links expire, get archived, or get replaced without you updating every place you linked to them. You have three versions of a course, and each one has its own payment link. You sunset version one. The link still lives in your welcome sequence for old subscribers. It still looks fine. But it doesn't work.
What to Check Right Now
- Open every email template that mentions a product or offer. Click every payment link yourself. Don't just scan it. Actually click it from a browser.
- Check your Stripe or PayPal dashboard. Find the date each payment link was created. If it's older than six months and you've made changes to that product, test the link.
- Search your email sequences and sales pages for hardcoded links to products you've updated, archived, or renamed.
- If you use landing page software, check that your embedded payment buttons are still connected to active products.
- Test from mobile. Payment links sometimes break differently on desktop versus app browsers.
The Real Cost
A broken payment link isn't a one-time loss. It compounds. Every time that email sends, every time that page goes out, every time a customer finds you and lands on that link, they bounce. If your welcome sequence sends 50 emails a week and the payment link is dead, you're losing dozens of potential sales quietly every single week. You're still paying for the traffic that drives them there. You're just not capturing the sale.
A working funnel with broken payment links is just expensive customer research.
Ongoing Checks Matter
The fix is simple: test your payment links monthly. Pick one day each month, open your main sales emails, and click every link. It takes 15 minutes. One broken link found and fixed in month two just paid for a year of that habit. The goal isn't to build a system that never breaks, it's to catch breaks fast before they cost you thousands in invisible lost sales.
