Introduction

Welcome to Mailprex — a simple, secure way to send emails from website contact forms without building a backend.

How it works

Your website form  →  POST /email/send  →  Mailprex API  →  Your inbox
                         (formToken)

1. Create a Mailprex account and verify your email.
2. Generate a form token in the dashboard (mk_live_… format).
3. Install the mailprex npm package or call the API directly.
4. Form submissions arrive at the email address on your account.
