TL;DR

Send transactional emails from your Lovable app using Resend — the developer-friendly email API.

When to Use Lovable + Resend

Use this integration when your Lovable project needs Resend to support a real product workflow, not just a demo. The best time to add it is after the first app flow is clear and before you send real users through the feature.

A good integration prompt should explain what triggers the integration, what data is sent or stored, what success looks like, what should happen when the integration fails, and which parts must stay server-side or private.

Define the exact user action that should trigger the integration.

Use test credentials, sandbox mode, or sample data first.

Keep private keys, tokens, and secrets out of frontend code.

Add useful loading, success, empty, and error states.

Common Mistakes to Avoid

Do not ask Lovable to add an integration without naming the real workflow. A vague request such as “connect Resend” gives less useful output than a specific instruction about the user action, stored data, success state, and error handling.

Do not connect production accounts too early. Build the interface, test with sample data, confirm the app behavior, and only then connect live credentials or production workflows.

Prompt Template for Lovable + Resend

Use this structure when asking Lovable to add Resend. Replace the bracketed fields with your own product details so Lovable understands the workflow and the safety requirements.

Add Resend to my Lovable app for [specific workflow]. When [user action] happens, the app should [expected integration behavior]. Store or send [data fields]. Show a loading state, success state, and clear error state. Keep private keys and secrets server-side. Use test data first and include notes for production setup, analytics tracking, permissions, and rollback.

This prompt works better than a one-line request because it defines the trigger, the data, the user-facing states, and the production guardrails. It also helps Lovable avoid putting sensitive logic in the wrong place.
