I replaced Stripe's dunning emails with SMS — here's the architecture and why it recovers 2x more revenue

Ale — Fri, 13 Feb 2026 19:52:20 +0000

The problem nobody talks about

If you're running a subscription SaaS on Stripe, you probably have a silent revenue leak: involuntary churn.

That's when customers churn not because they want to, but because their card expired, got declined, or hit a spending limit. Stripe retries the charge a few times, sends some dunning emails, and if nothing works — subscription canceled.

The numbers are brutal:

20-40% of all subscription churn is involuntary
Stripe's dunning emails have a ~20% open rate
Most of those emails land in Promotions or Spam

I kept seeing this across every project I worked on and decided to fix it.

Why SMS beats email for payment recovery

The insight is simple: people don't check email in real-time, but they check texts immediately.

Channel	Open Rate	Avg Response Time
Email	20-25%	Hours to days
SMS	45%	Under 5 minutes

When a payment fails and you text the customer "Hey Alex, your $49 payment didn't go through — tap here to update your card", they do it right then. No logging in, no finding the right settings page. One tap → Stripe's Customer Portal → card updated → next retry succeeds.

The technical approach

Here's the architecture I ended up with:

Stripe webhook (invoice.payment_failed)
→ Validate event + extract customer data
→ Check retry attempt number (1st, 2nd, 3rd)
→ Select SMS template based on attempt
→ Generate Stripe Customer Portal session URL
→ Send SMS via provider (Twilio/MessageBird)
→ Log event for analytics

Key decisions:

1. Stripe Restricted API Keys

Don't use your full secret key. Create a restricted key with only the permissions you need:

Customers: Read
Invoices: Read
Customer portal sessions: Write

This is the minimum to read customer info, check the invoice, and generate a portal link.

2. Customer Portal Session URL

This is the magic piece. Stripe's Customer Portal lets your customer update their payment method without any authentication on your side:

const session = await stripe.billingPortal.sessions.create({
  customer: customerId,
  return_url: 'https://yourapp.com/account',
});
// session.url → one-tap link for the SMS

The URL is short-lived and scoped to that customer. Perfect for SMS.

3. Escalating SMS templates

Don't send the same message three times. Escalate:

Attempt 1 (friendly): "Hi {name}! Your ${amount} payment didn't go through. Update your card here: {link}"
Attempt 2 (reminder, +24h): "Reminder: your ${amount} payment is still pending. Tap to update: {link}"
Attempt 3 (urgent, +48h): "Last chance — update your card now or your subscription will be canceled: {link}"

Each attempt catches a different segment. Some people just need a nudge, others need urgency.

4. Webhook handling

The critical webhook event is invoice.payment_failed. Key fields:

// Inside your webhook handler
const invoice = event.data.object;
const customerId = invoice.customer;
const amountDue = (invoice.amount_due / 100).toFixed(2);
const attemptCount = invoice.attempt_count;
const subscription = invoice.subscription;

// Only act on subscription invoices, not one-time
if (!subscription) return;

// Get customer phone
const customer = await stripe.customers.retrieve(customerId);
const phone = customer.phone; // or from your own DB

5. Don't spam

Important guardrails:

Only send for subscription payments, not one-time charges
Max 3 SMS per failed invoice
Don't send if the payment was already recovered between retries
Respect timezone — nobody wants a payment text at 3 AM
Check invoice.status before sending — if it's paid, skip

Results

After implementing this on my own SaaS:

Recovery rate went from ~18% (email only) → ~42% (email + SMS)
Average time to card update: under 8 minutes after SMS
Customer complaints about the texts: zero (they're grateful, actually)

I turned it into a product

After building this for the third time across different projects, I packaged it into RecoverPing (recoverping.com).

It's basically all of the above without writing code:

Paste your Stripe restricted API key
We register the webhook automatically
Customize your SMS templates
Done in 5 minutes

Plans start at $19/mo. Coming soon: WhatsApp and Telegram channels.

But if you prefer to build it yourself, everything above should get you there. The core idea is simple: reach your customers where they actually look.

TL;DR

Involuntary churn is 20-40% of all subscription churn
Stripe dunning emails: 20% open rate. SMS: 45%.
Use invoice.payment_failed webhook + Stripe Customer Portal sessions + SMS
Escalate urgency across retries
Went from 18% → 42% recovery rate

Why I Built 2Perks — Helping Small Businesses Grow Through Honest Feedback and Reputation

Ale — Wed, 30 Jul 2025 08:55:42 +0000

🌟 Why I Built 2Perks — Because Every Business Deserves Honest Feedback

If you’ve ever run a small business, you know the feeling:

you work hard to make customers happy… and yet one bad review on Google can undo months of effort.

Most businesses fear reviews — when in reality, reviews are a gift.

They tell you what’s working, what’s broken, and what your customers truly feel.

But today, feedback often comes too late — after the damage is public.

That’s why I built 2Perks:

to make it easy for small businesses to collect feedback early, fix problems privately, and grow their online reputation ethically.

💡 The Mission

Our mission is simple but powerful:

“Help small businesses grow through honest, transparent, and policy-safe feedback.”

We believe in a world where:

Feedback is an opportunity, not a threat.
Reputation is earned through service, not marketing tricks.
Technology empowers small businesses to listen better, not hide problems.

2Perks exists to make that vision real — one review at a time.

🧭 The Problem We Saw

Most local businesses (restaurants, clinics, service providers, etc.) depend heavily on online reputation.

But they struggle with two things:

Happy customers stay silent.

People rarely leave positive reviews unless asked.
Unhappy customers go public.

Instead of sharing feedback privately, they post frustration online.

Traditional “review filtering” tools try to solve this — but they break Google’s rules.

They hide or block bad reviews, which can get businesses penalized or banned.

We took a different route.

⚙️ Our Approach — “Policy-Safe Feedback Routing”

2Perks doesn’t filter. It routes feedback.

Happy customers → Encouraged to post public reviews (Google, Yelp, TripAdvisor)
Unhappy customers → Invited to share feedback privately through a simple form

This way, the business can fix the issue before it becomes public,

and both sides leave the interaction feeling heard and respected.

It’s honest, transparent, and 100% compliant with platform policies.

🌱 Why Feedback Matters

Feedback is not just data — it’s the heartbeat of a healthy business.

When you collect feedback consistently:

You discover recurring problems before they spread.
You spot loyal customers who love you (and could refer others).
You gain insights that improve your product and service.

Every review — good or bad — is a piece of truth that helps you grow.

Without feedback, you’re guessing.

With it, you’re improving.

🚀 Why Online Reputation Is Everything

In today’s digital economy, your online reputation is your storefront.

Before a customer books an appointment or places an order, they check your reviews.

One negative comment can cost you a sale; a consistent 5-star presence can multiply your business.

We designed 2Perks to make reputation building easy, ethical, and automated:

Share one link or QR code.
Collect feedback from every customer.
Turn positive experiences into 5⭐ reviews.
Handle complaints privately, before they escalate.

You don’t need a marketing team or complex tools — just a few minutes and a desire to listen.

💬 The Bigger Picture

At its core, 2Perks isn’t just a review tool — it’s a trust tool.

We want to restore balance between businesses and customers.

Between reputation and reality.

Between being reactive and being proactive.

Because when small businesses listen, improve, and grow — everyone wins.
