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 Instant's email's from and reply-to fields 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. Until the address is verified, emails will continue to be sent from Instant's default auth sender (auth@pm.instantdb.com).
