Quickstart: Email

Communicate to and from your app by email

Send an email from your app

Write this function into the Server Module:

def send_email(address):
      from_name="Anvil Forum",
      subject="Have you used the Anvil Forum?",
      html='The Anvil <a href="">Forum</a> is friendly and informative.',
      text="The Anvil Forum ( is friendly and informative.",

Call your server function from the client

Go to the code for Form1. It looks like this:

Code View for Form1

At the end of the __init__ method, write these lines (replace the <your email address> with your actual email address):

    email_address = "<your email address>"'send_email', email_address)

This means your function will run when the app starts.

Run your app

Now click the ‘Run’ button at the top of the screen.

Running your app in the editor

Check your email - you will have an email from your app.

Receive emails from your app

Stop your app and go to your Server Module.

Write this function:
def message_handler(msg):
  to_address = msg.addressees.to_addresses[0].raw_value
  msg.reply(f"Your email was sent to {to_address} and received successfully.")

Send your app an email

At the bottom of the Server Module, there is a message like this:

Message showing the email address associated with your app

Any emails sent to any address ending in will be receieved by my app - your app will have a similar but different address.

Open your favourite email client and send an email to hey-it-works@<your-app-id>, where <your-app-id> would be ahd2umld63ixj6o6 in my case.

You should receive a reply containing the text Your email was sent to hey-it-works@<your-app-id> and receieved successfully.

(To set up a nicer email address for your app, see deployment.)

Copy the example app

Click on the button below to clone a finished version of this app into your account.
