Payment confirmations

Instant receipts via email when payments succeed. Professional and automatic.

Failed payment recovery

Alert customers immediately when payments fail. SMS for urgency, email for details.

Upcoming renewal reminders

Notify before charges to reduce surprise cancellations and chargebacks.

Multi-channel urgency

Email for routine receipts, SMS for failed payments that need immediate action.

Invoice delivery

Send invoices automatically by linking to your payment processor's hosted invoice pages.

Dunning sequences

Use events for first failures, reminders, and final notices to support your existing dunning strategy.

How it works

typescript

// Stripe webhook handler
app.post('/webhooks/stripe', async (req, res) => {
  const event = stripe.webhooks.constructEvent(req.body, sig, secret);

  if (event.type === 'invoice.payment_succeeded') {
    await sendivent
      .event('payment.succeeded')
      .to({ email: event.data.object.customer_email })
      .payload({
        amount: formatCurrency(event.data.object.amount_paid),
        invoiceUrl: event.data.object.hosted_invoice_url,
        nextBillingDate: event.data.object.next_payment_attempt
      })
      .send();
  }

  if (event.type === 'invoice.payment_failed') {
    await sendivent
      .event('payment.failed')
      .to({
        email: event.data.object.customer_email,
        phone: customer.phone // SMS for urgency
      })
      .payload({
        amount: formatCurrency(event.data.object.amount_due),
        updatePaymentUrl: 'https://app.example.com/billing',
        retryDate: event.data.object.next_payment_attempt
      })
      .send();
  }
});

Implementation steps

Connect to your payment processor

Trigger Sendivent events from Stripe webhooks, or your own payment system.

Configure notification rules

Set which payment events trigger which channels — SMS for failures, email for receipts.

Recover failed payments

Use multiple failed-payment events over time (immediate, reminder, final notice) to support your dunning flow.

Why payment notifications matter

Payment notifications directly impact revenue. Failed payment emails and SMS alerts are often the only warning a customer sees before their subscription lapses:

Failed payment alerts recover churned customers — every day of delay loses money
Renewal reminders reduce involuntary churn and chargebacks
Professional receipts build trust and reduce "I didn't authorize this" disputes

The complete payment notification flow

payment.succeeded — receipt with amount and invoice link
payment.failed — urgent alert with update payment CTA
payment.retry_scheduled — reminder before automatic retry
payment.method_expiring — proactive card expiration warning
subscription.renewed — confirmation of subscription renewal
subscription.cancelled — confirmation and win-back opportunity

Multi-channel strategy

Email: Receipts, invoices, routine confirmations
SMS: Failed payments, expiring cards, urgent action needed
Slack: Internal alerts for high-value failures or disputes

With Sendivent, you configure which events use which channels once, and we apply that routing every time your app emits those events.

Template Examples

Payment Receipt (Email)

<h2>Payment Received</h2>

<p>Hi {{user.name}},</p>

<p>We've received your payment of <strong>{{payload.amount}}</strong>.</p>

<p>
  <a href="{{payload.invoiceUrl}}">View Invoice</a>
</p>

<p>Your next billing date is {{formatDate payload.nextBillingDate "MMMM D, YYYY"}}.</p>

<p>Thanks for being a customer!</p>

Failed Payment (SMS - Urgent)

Payment of {{payload.amount}} failed. Update your card to avoid service interruption: {{payload.updatePaymentUrl}}

Failed Payment (Email)

<h2>Action Required: Payment Failed</h2>

<p>Hi {{user.name}},</p>

<p>Your payment of <strong>{{payload.amount}}</strong> could not be processed.</p>

<p>Please update your payment method to continue your subscription:</p>

<a href="{{payload.updatePaymentUrl}}" style="...">Update Payment Method</a>

{{#if payload.retryDate}}
<p>We'll automatically retry on {{formatDate payload.retryDate "MMMM D"}}.</p>
{{/if}}

Frequently asked questions

How do I integrate with Stripe webhooks?

Listen for Stripe webhook events like invoice.payment_succeeded and invoice.payment_failed, then trigger the corresponding Sendivent event with payment details.

Should I use SMS for failed payment alerts?

Yes, SMS is highly effective for failed payments. The urgency of SMS increases response rates and helps recover revenue faster than email alone.

Can I set up automated dunning sequences?

Yes. Your billing system or payment processor controls when to retry and send follow-ups. At each step, trigger the appropriate Sendivent event (for example payment.failed.first, payment.failed.reminder, payment.failed.final) and we'll deliver across email and SMS.

How do I include invoice PDFs in payment receipts?

Include the invoice URL in your payload. Most payment processors like Stripe provide hosted invoice URLs that you can link to in your email template.
