Muli

Introduction to Muli

Muli is an email automation platform that integrates directly with Stripe to send event-triggered, personalized emails. It is designed for businesses that process payments and manage subscriptions through Stripe and need to maintain timely, relevant communication with customers without manual intervention. The platform targets SaaS companies, subscription-based services, and e-commerce businesses seeking to reduce operational overhead while improving customer engagement and retention.

Muli eliminates the need for custom code or complex workflows by providing a no-code interface for configuring email responses to Stripe events. It supports common business scenarios such as onboarding, payment confirmations, subscription changes, and churn prevention—enabling teams to automate high-impact communications reliably and consistently.

Key Takeaways

• Visual drag-and-drop email builder with real-time preview
• Trigger-based email delivery tied to Stripe events (e.g., customer.subscription.deleted, invoice.paid, charge.failed)
• Custom branding options including colors, fonts, and logo integration
• Delivery analytics tracking bounces, opens, clicks, and delivery rates
• Test email functionality using realistic Stripe test data
• Code-free setup completed in under two minutes
• Support for all Stripe event types in the Pro plan
• Email delivery logs and template management

How Muli Works

Muli connects to a user’s Stripe account via OAuth, granting read-only access to relevant event data. Once connected, users configure email triggers by selecting specific Stripe events and associating them with prebuilt or custom email templates. Templates are created using the visual editor, which allows insertion of dynamic fields (e.g., customer name, invoice amount, subscription status) pulled directly from Stripe payloads.

When a matching Stripe event occurs—such as a subscription cancellation or successful invoice payment—Muli receives the webhook payload, processes it, and sends the corresponding email within seconds. Users can preview emails before activation, send test messages with simulated customer data, and monitor performance through built-in analytics dashboards. No server-side code or infrastructure management is required.

Core Benefits and Applications

Muli addresses recurring operational challenges in customer lifecycle management: reducing delayed or missed outreach during critical moments (e.g., cancellation windows), eliminating manual copy-paste workflows across tools, and standardizing branded communication at scale. Common applications include automated subscription confirmation emails, failed payment recovery sequences, post-cancellation win-back campaigns, and invoice payment receipts. By shortening the time between Stripe events and customer communication—from an average of 12 minutes manually to under 2 seconds—Muli helps mitigate silent churn and improves revenue retention. The platform also reduces weekly manual email effort by approximately 3.2 hours per team member, based on reported usage patterns.
