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

Create an account at https://www.flapmail.net/
Create a sender
Generate a token
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", "jane@example.com");
formData.append("message", "Hello from my website");

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




## Docs and examples

I published examples for HTML, PHP, Node.js, Java, and Python here:

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