Transactional email
Transactional email for vibe-coded apps
Lovable, Bolt, v0, and Cursor can ship auth UI in an afternoon. Notify delivers password reset, magic link, and receipt mail from your domain — one API call, secrets on the server, optional MCP for setup.
Three flows to wire once
- Password reset — hashed token in your DB, link in HTML, Notify delivers
- Magic link or OTP — same pattern, short TTL, rate-limit the request endpoint
- Receipt — idempotent send from your payment webhook (Stripe, etc.)
New accounts start sandbox-only until domain verification. Rehearse with POST /api/email/send/test or the dashboard guided test.

Frequently asked questions
What is a vibe-coded app?
An app scaffolded quickly with AI builders (Lovable, Bolt, v0, Cursor, Replit Agent, and similar). UI and routes ship fast; transactional email still needs a provider, verified domain, and server-side secrets.
Why use Notify for AI-built apps?
One HTTPS send endpoint, HTML you already have, flat pricing (Free 1k/mo, Pro $10/10k as of Nov 2026), and optional notifycx-mcp for domain setup in Cursor. No template studio or newsletter surface.
Can I paste a prompt into Lovable or Bolt to add email?
Yes. The full guide includes a copy-paste prompt that wires NOTIFY_API_KEY on the server, password reset, magic link or OTP, and payment receipts via POST /api/email/send.
Does Notify work with Supabase Auth from an AI builder?
Use Supabase Send Email Hook to an Edge Function that calls Notify — not Custom SMTP. See the Supabase without SMTP doc and the step-by-step recipe linked from the guide.
Should production email use MCP?
No. MCP (notifycx-mcp) is for IDE setup and testing. Production sends belong in your app with the notifycx SDK or fetch.
