How to send contact form emails with a simple token-based endpoint

Most small websites eventually need the same thing: a contact form that sends an email.

That sounds simple, but the implementation often becomes more work than expected:

• SMTP credentials
• mail libraries
• server-side validation
• anti-abuse handling
• formatting the submitted fields
• deployment differences between hosts

I built FlapMail as a lightweight way to handle this pattern with a token-based submit endpoint.

It is meant for transactional messages such as:

• contact forms
• quote requests
• help desk forms
• HR forms
• app alerts
• script notifications

It is not a bulk email or newsletter tool.

Basic flow

1. Create an account at https://www.flapmail.net/
2. Create a sender
3. Generate a token
4. Send form data to:

LINK TO API
https://app.flapmail.net/api/submit.php

## Example payload

js
const formData = new FormData();
formData.append("token", "YOUR_FLAPMAIL_TOKEN");
formData.append("name", "Jane Doe");
formData.append("email", "[e-mail]");
formData.append("message", "Hello from my website");

await fetch("https://app.flapmail.net/api/submit.php", {
method: "POST",
body: formData
});

I would appreciate feedback from developers who maintain small websites, landing pages, dashboards, or AI-generated projects.
