I need to send an automatic email when someone successfully subscribes via Stripe:

Email trigger: When Stripe webhook confirms successful subscription payment

Email content:
- Subject: "Welcome to [Your Tool Name] - You're all set!"
- "Thanks for subscribing! Your account is now active"
- "You have [X] credits to use this month"
- Direct link to access your tool: [your app URL]
- "Need help? Reply to this email and I'll personally assist you"
- Simple, clean email template

Use Resend integration to send this automatically. The email should arrive within 2-3 minutes of payment.

Please set up automatic welcome email for new subscribers using Resend.
