Email

The portal sends transactional email via Resend. Four templates ship in the box:

• verification — the email link a new buyer clicks to confirm their address.
• passwordReset — when a buyer requests a password reset.
• welcome — sent after email verification.
• proPurchaseConfirmation — sent after a successful Pro purchase, with the GitHub invitation and clone instructions.

Required environment variables

RESEND_API_KEY=re_...
RESEND_FROM_EMAIL="AI Cost Gate <noreply@aicostgate.com>"

The from address must be on a domain you've verified in Resend.

Optional: audience

To also collect a marketing audience, set:

RESEND_AUDIENCE_ID=...

The newsletter form on the landing page will subscribe buyers to that audience.

Custom templates

Templates live in emails/*.tsx using react-email. After editing:

pnpm email:dev   # preview at http://localhost:3000

There is no separate export step — the templates are imported directly by the email-sending code.
