Google Form - Response Emailer

Google form to Gmail header image.

SKILL LEVEL:  Beginner

In this article, we will be using Google Apps Script (GAS) to process a Google Forms submission and send an email using Gmail.  Let's dive in!

Creating your form

You can use your own form, or create one if you're starting from scratch. For this article, let's create a form that customers can use to submit feedback on a service or product.

  1. Go to Google Forms
  2. Click the Blank form to create an empty form.
  3. Add a few fields:
    • Customer Name
    • Phone Number
    • Email Address
    • Feedback

It should look something like this:

Customer feedback Google Form sample

Once your complete, don't forget to adjust the settings to allow submissions from outside your Google Workspace domain.

  1. Click Settings on the top navigation bar.
  2. Expand the section titled Responses
  3. Toggle the option "Restrict to users in your domain and its trusted organizations" to off.
Google Form settings

Edit your form's scripting

In the upper right hand of your form, click the vertical elipsis and select Script Editor.

Locating the script editor

Now that you're in the script editor, we'll need to copy/paste the Google Apps Script (GAS) code into the editor.

  1. Let's start be giving the project a name. Click the Untitled Project text and change it to something like Customer Feedback Form Script.
  2. Delete the contents of by highlighting the funtion myFunction(){} and pressing delete.
Renaming project and deleting sample code

Now let's copy the new code from the this blog and paste it into the file.

//#### Variables -  Complete this section ####
// Email Header information
const emailHeader = {
  to: "[email protected]",
  fromName: "KilPen Technical Services",
  subject: "Someone submitted feedback on a Google Form."

// Body of the email being sent by this script
const emailBody = {
  imageUrl: "",
  messageIntro: "Hello Customer Care",
  messageMain: "Someone has completed the support request form.  Please review the below information and create a support ticket.",
  messageOutro: "KilPen Automator",
  footerText: "Need assistance?",
  footerButtonText: "KilPen Helpdesk",
  footerButtonUrl: "",
  formSourceUrl: "[UPDATE THIS]/edit"
//#### END VARIABLES ####

function onFormSubmit(e) {   
  Logger.log(`Starting form auto-responder...`);


  var items = e.response.getItemResponses();
  var respondent = {
    title: "Respondent",
    ans: e.response.getRespondentEmail()

  var responses = [];

  for (var i in items){
    var response = {
      title: items[i].getItem().getTitle(),
      ans: items[i].getResponse()

  Logger.log(`Form contains ${responses.length} items.`);

  var templ = HtmlService
  templ.responses = responses;
  templ.emailBody = emailBody;
  Logger.log(`Preparing message for email contents...`);
  var message = templ.evaluate().getContent();

  Logger.log(`Sending Email...`);   
    name: emailHeader.fromName,
    subject: emailHeader.subject,
    htmlBody: message

  Logger.log(`Message sent: ${message}`);
    Logger.log(`Something went wrong. ${e}`)


function grantPermissions(){
 var form = FormApp.getActiveForm().getResponses();



So far so good! Now let's add the email template that will be sent when a customer completes the feedback form.

  1. In the Files section of the script editor, click the + symbol and select HTML.
  2. Type 'template' to change the file's name.
Creating a new HTML file
The name of this file must be exactly 'template' or the email will not generate properly. Once you type the name, the script editor will add the .html which is okay.
  1. Copy and paste the below HTML into the template.html file.
<!doctype html>
    <meta charset="utf-8">
    <!-- utf-8 works for most cases -->
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <!-- Forcing initial-scale shouldn't be necessary -->
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <!-- Use the latest (edge) version of IE rendering engine -->
    <title>Form Responder</title>
    <!-- The title tag shows in email notifications, like Android 4.4. -->
    <!-- Please use an inliner tool to convert all CSS to inline as inpage or external CSS is removed by email clients -->

Customize the script

In the script editor, navigate to the file and locate the Variables section at the very top of the file.

Let's work backwards for a second and review the final email that will be sent. Then the variables might make more sense.

Here is what the final email will look like:

email tagged with variables

And here are the variables:

Screen shot of the default variables

The variables are broken into two sections:

  1. Email Header (const emailHeader)
    • to: The email address that will receive this email notification.
    • fromName: The name on the email whom it was sent from.
    • subject: The subject line of the email that is being sent.
  2. Email Body (consnt emailBoday)
    • imageUrl: A URL with an image to display in the email header.
    • messageIntro: The name of who this message is addressed to.
    • messageMain: The main body of the message.
    • messageOutro: The name of whomever is sending the message.
    • footerText: The message above the button.
    • footerButtonText: The text on the surface of the button.
    • footerButtonUrl: The URL we want the button to point to.
    • formSourceUrl: The URL of the form we created.

Set a form trigger

On the left hand side of the script editor, select the Triggers option. It's the alarm clock looking logo.

Setting a trigger image

Now click the blue +Add Trigger button in the lower right.

Here are the values we're looking for:

  • Choose which function to run: OnFormSubmit
  • Choose which deployment should run: Head
  • Select event source: From form
  • Select event type: On form submit

Now click the Save button.

You'll be prompted to authorize your script to run.

  1. Select your Google Account which will be running this script.
Granting permission to script - image 1
  1. Click "Allow"
Granting permission to script - image 2

Give it a test!

That was it. Let's test a form submission and wait for the email.

  1. Open the tab which had the Customer Feedback form. It's probably to the left of script editor tab.
  2. Select the eyeball icon which is the form preview.
Locating the form's preview icon
  1. The LIVE version of your form will open in another tab. This is the URL that we want to share with our customers. Let's enter some test data and click submit.
Completed test form sample

If you were successful, the email address specified in the Variables should have received an email that looks like this:

End result email image
