Email Validation for Stripe Billing Workflows
For SaaS businesses using Stripe, ensuring every customer email on file is valid prevents billing disruptions and reduces involuntary churn. Verifyr integrates seamlessly to maintain accurate subscriber contact data.
The problem
Invalid customer emails in Stripe lead to failed invoices, missed payment recovery attempts, and increased customer support tickets. When a subscription fails due to an outdated or incorrect email, your revenue takes a hit, and your team spends valuable time manually tracking down customers. This often results in lost subscriptions, especially for automated payment retry sequences that rely on email notifications to update payment methods.
Many SaaS platforms onboard users without robust real-time email verification, leading to a build-up of bad data over time. This becomes critical when integrating with billing systems like Stripe, where email is a primary communication channel for transaction receipts, failed payment alerts, and subscription changes. Proactive validation prevents revenue leakage and keeps your subscriber base healthy, avoiding costly retroactive cleanups.
How Verifyr solves it
Concrete example
// Example: Validate email before updating a Stripe customer
const verifyr = require('verifyr'); // Assuming SDK
const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY);
async function updateStripeCustomerEmail(customerId, newEmail) {
const validation = await verifyr.validate(newEmail);
if (!validation.valid || validation.disposable) {
throw new Error('Invalid or disposable email address provided.');
}
const customer = await stripe.customers.update(customerId, {
email: newEmail,
});
return customer;
}
