How It Works

From Stripe event to customer inbox in seconds

Three steps. Two minutes. Zero code. Here is how Muli automates your Stripe customer emails.

Step 01

Connect your Stripe account

Link your Stripe account with one click using Stripe Connect. Muli securely listens to your Stripe events — no API keys to copy, no webhooks to configure manually.

  • One-click Stripe Connect integration
  • No API keys or webhook URLs to manage
  • Secure OAuth-based authentication
  • Works with Stripe test and live modes
Step 02

Build your email template

Use the visual editor to create your email. Pick a preset template or start from scratch. Add your brand colors, logo, and copy. Use smart variables like {{customerName}} and {{amount}} to personalize every message.

  • Drag-and-drop block editor
  • Pre-built templates for common scenarios
  • Smart variables from Stripe data
  • Real-time preview with test data
Step 03

Choose your trigger and go live

Select which Stripe event should trigger this email — like a subscription cancellation, failed payment, or successful charge. Enable the template, and Muli handles everything automatically from that point on.

  • Pick from 15+ Stripe event types
  • Enable/disable templates instantly
  • Test with simulated Stripe events first
  • Emails sent within seconds of the event
Done! Your emails are now fully automated.
