Resend

Transactional email — contact forms, receipts, confirmations. Connected with your own key — encrypted, server-side only, never exposed to the browser.

What you can build

Email me every contact-form submission
Send booking confirmations to customers
Send a receipt email after each successful order

Prompts like these, typed into opix, produce working Resend features.

Connect it in three steps

01

Create the key

Generate an API key in your Resend account — the link below takes you to the exact page.

02

Paste it in opix

Open your project → Connectors, paste the key. It's stored encrypted and injected server-side; even you only see the last four characters afterwards.

03

Prompt what you want

Describe the feature in chat — opix writes the Resend code with honest fallbacks built in.

Keys & setup

Environment variableRequired
RESEND_API_KEYYes

Without a verified domain, Resend delivers only to your own address (from onboarding@resend.dev). Verify your domain in Resend to email customers.

Honest by default

Apps built with opix never pretend. Without a key, submissions still persist to the database; sends are skipped silently and admin UI shows an 'email notifications off' hint.
