Vue Send Email Guide

(Free And Without Backend)

Vue Send Email

We all know that Vue's primary purpose is to be running in browsers. Because of that, it's super powerful but also has quite a few limitations. For example, being client-side only, it can't do certain things that we would take for granted on the server-side. A good example would be sending emails. As all the client code is public, you wouldn't want to expose your mail server credentials to the whole world.

So the question is, how to send emails from Vue without a backend? Luckily, this guide answers it perfectly.

P.S. If you want to know how to send form data (such as contact form fields), you can read the Vue Contact Form guide.

Create the email function inside of Vue App

You'll send the email on that function. We’ll need to get two arguments for it to work: endpoint URL and "data." Then, a simple POST request and returning the state with the response of that request. We'll be using vue hooks, but the example is straightforward to port to the class components. See the sample code.

import { ref } from 'vue'

const UseEmail = (endpointUrl) => {
  const submitted = ref(false);
  const loading = ref(false);
  const error = ref();

  function sendEmail(data) {
    loading.value = true;
    submitted.value = false;
    error.value = undefined;

    fetch(endpointUrl, {
      method: "POST",
      headers: {
        Accept: "application/json",
        "Content-Type": "application/json",
      body: JSON.stringify(data),
      .then((response) => {
        // Endpoint thinks that it's likely a spam/bot request, you need to change "spam protection mode" to "never" in HeroTofu forms
        if (response.status === 422) {
          throw new Error("Are you robot?");

        if (response.status !== 200) {
          throw new Error(`${response.statusText} (${response.status})`);

        return response.json();
      .then(() => {
        submitted.value = true;
        loading.value = false;
      .catch((err) => {
        error.value = err.toString();
        loading.value = false;


  return {


export default UseEmail;

Create a new backend, set your email, spam protection

Go to to make your first form after you have confirmed your email address. In this case, the form will function as our API backend/endpoint. Attach your preferred email address where you'd like to receive your data submits. Be sure to select spam protection as "never." You'll be sending API requests yourself, so they shouldn't ever be detected as spam by HeroTofu.

Remember to copy the endpoint URL once you hit submit.

Add component into your app, pass some data

The last step is implementation. Call your created function with the endpoint URL and actual data. HeroTofu will forward that data to your email.

  <div class="app">
    <header class="app-header">
      <img src="./assets/logo.png" alt="Logo" class="app-logo" />
      <div style="margin: 1rem 0; font-size: 2rem">
        <span v-if="submitted"> Done, email was sent! </span>
        <span v-if="error"> Unexpected error: {{ setError }} </span>
        <span v-if="loading"> Email is being sent now... </span>
        <button style="margin: 1rem 0" @click="sendExample">
          Send test data

import UseEmail from "./UseEmail";

export default {
  name: "App",

  setup() {
    const { loading, submitted, error, sendEmail } = UseEmail(endpointUrl);
    const sendExample = () => {
        example_user: "",
        example_data: new Date().toISOString(),

    return { loading, submitted, error, sendExample };

That's it!

You can now send emails from your Vue application. All without the burden of the server/backend code.
