Email SDK - One email SDK for every provider

by•
Email SDK is a lightweight TypeScript library for sending email through Resend, Postmark, SendGrid, Mailgun, Brevo, SMTP, and more with one clean API. Add adapters, set fallbacks, retry failed sends, run test sends from the CLI, and keep provider-specific code out of your app. Write your email logic once, then use whatever provider makes sense.

Hey ProductHunt 👋 I’m Leo, a 14 y/o solo dev behind Email SDK. I built this because I kept running into the same annoying thing across projects: every email provider has its own SDK, its own setup, and its own little way of doing the same basic job. Sending email should not lock your app into one provider. I wanted one small SDK where I could write the email code once, use Resend on one project, Postmark on another, SMTP somewhere else, and switch later without digging through the whole codebase. So I made Email SDK. It gives you one createEmailClient() setup, one send() call, and swappable adapters underneath. It supports Resend, Postmark, SendGrid, Mailgun, Brevo, MailerSend, Mailchimp Transactional, SparkPost, Loops, Plunk, Mailtrap, Scaleway, ZeptoMail, MailPace, and built-in SMTP without Nodemailer. It also has fallbacks, retries, hooks, batch sending, and a small CLI for checking config and sending test emails. It’s open source, fully typed, and meant to stay boring in the best way: simple email sending that does not trap you in one provider. Would love to hear what provider you use today, and which adapter you’d want next. 👀
