Your AI built the app. We'll send its emails.
Hassle-free, affordable email for apps built with Cursor, Claude, Lovable or Bolt. Sign-ups, password resets and receipts — four SMTP settings or one pasted prompt, and you're sending.
500 emails/month free · UPI & cards · never auto-renews
Add transactional email to this app using SMTP.
Read these from environment variables (never hard-code them):
SMTP_HOST=smtp.email4vibecoder.com
SMTP_PORT=587 # STARTTLS (or 465 for implicit TLS)
SMTP_USER=<username from the dashboard>
SMTP_PASS=<password from the dashboard>
MAIL_FROM=hello@<my verified domain>
Create one sendEmail(to, subject, html) helper using this stack's
standard SMTP library (Nodemailer for Node.js, smtplib for Python,
Swiftmailer/Symfony Mailer for PHP), then use it for sign-up
confirmation and password-reset emails.
Requirements:
- The send must run on the server, never in browser code.
- Reuse one transport/connection rather than creating one per message.
- Log the real error and surface a friendly one; never fail silently.
- Do not add a provider SDK — plain SMTP only.From zero to sending in three steps
No SDKs, no approval queues, no wrestling with DNS guides.

Drop the settings into your .env — or paste the prompt into your AI assistant — and send.
Everything your app needs to send email. Nothing it doesn't.
Made for AI-built apps
Cursor, Claude, Lovable, Bolt or Replit already know SMTP. Paste our prompt and your assistant wires up sign-up, reset-password and receipt emails for you.
Works with any stack
Plain SMTP on ports 587 and 465 — no SDK to install, no vendor lock-in. If your framework can send email, it works here.
Built to reach the inbox
Every email is DKIM-signed for your domain, with SPF alignment and TLS. We hand you the exact DNS records to paste.
