Muli uses Stripe Connect for a secure, one-click integration. You authorize Muli to listen to your Stripe events — no API keys to copy, no webhook URLs to configure. You can disconnect at any time from your dashboard.
Muli supports all major Stripe events including customer.subscription.deleted (cancellations), invoice.payment_failed (failed payments), checkout.session.completed (new purchases), customer.subscription.updated (plan changes), and many more. You choose which event triggers each email template.
No. Everything works through the visual interface — from connecting Stripe to building email templates to going live. There are no webhooks to configure, no HTML to write, and no deployment steps.
Emails are typically sent within seconds of the Stripe event occurring. Muli processes incoming webhooks in real-time and delivers emails through Resend, a high-performance email infrastructure with a 98.7% delivery rate.
Yes. You can use smart variables like {{customerName}}, {{customerEmail}}, {{amount}}, {{productName}}, and more. These are automatically filled with real data from the Stripe event when the email is sent.
The Free plan gives you access to the full email editor, all preset templates, and 3 test emails per day — but you cannot enable templates for production sending. Paid plans (Starter and Pro) let you enable templates so emails are sent automatically when Stripe events occur, plus unlimited test emails.
Absolutely. Muli offers two testing modes: Quick Test sends an instant preview to your inbox, and Stripe Test simulates a real Stripe webhook event end-to-end. Free plan users get 3 test emails per day; paid plans get unlimited testing.
Yes. Muli verifies every incoming Stripe webhook signature to prevent spoofing. We use Stripe Connect (OAuth) for authentication — we never store your Stripe secret keys. All data is transmitted over HTTPS.
Yes. You can customize colors, add your logo, set a custom sender name, and create reusable style presets. Pro plan users also get access to advanced custom styles and themes.
Your templates remain saved but are automatically disabled for production sending. You can still access the dashboard, edit templates, and send test emails (up to 3 per day). Re-subscribe anytime to re-enable automated sending.
