Hey devs! Every time I deployed an MVP on Railway or Render free trials, sending emails with Nodemailer, smtplib, net/smtp, etc. failed because outbound SMTP ports (25, 465, 587) are strictly blocked. Plus, services like Resend force you to buy and setup a custom domain first.
So I built SendLib, a dedicated, production-ready email API for devs.
SendLib lets you connect a Gmail account (e.g. [email protected]) via Google OAuth 2.0 and gives you a secure REST API to send transactional emails (welcome emails, password resets, OTPs) from wherever your product is hosted, straight to your user's inbox.
How it works:
1. Connect your product Gmail account via 1-click Google OAuth.
2. Grab an API key from your dashboard.
3. Send a single HTTP POST request from any language.
Free tier: Connect up to 10 Gmail accounts & send up to 500 emails/day per account (2,000/day for Workspace).
