You can customize all aspects of your Instant app's "magic code" email: the body (plain text or HTML), subject, sender name, and even the from address.

#Dashboard

To start, go to your Dashboard's auth tab. Click "Custom Magic Code Email", and you're ready to go.

#Variables

We provide a handful of variables you can use in both your subject line and body template:

• {code}, the magic code, e.g. 123456. Note, this variable is required in both the subject and body.
• {user_email}, the recipient user's email address, e.g. happyuser@gmail.com
• {app_title}, your app's name

Using a variable is as easy as adding the variable's name in curly brackets, e.g. {variable_name}.

<p>Hi {user_email}, here's your code for {app_title}:</p>
 
<strong>{code}</strong>

#Custom sender addresses

You can also set the from and reply-to fields on Instant's emails to an address on your own domain.

If you provide a custom sender address, you'll need to confirm it before we can start delivering from it.

Our email partner, Postmark, will send a confirmation to the provided address with a link to verify it. Until the address is verified, emails will continue to be sent from Instant's default auth sender (auth@pm.instantdb.com).
