# Postmark

Postmark sends your app emails through your own [Postmark](https://postmarkapp.com/) account. You'll need a Postmark account with an authenticated sender domain before you start.

### 1. Get your Postmark Server API token

In your Postmark dashboard, navigate to **Servers → \[Your Server Name] → API Tokens** and copy the **Server API token**.<br>

### 2. Add the API token to Gift Card Factory

1. Open **Settings → App Emails Sending** in the Gift Card Factory app.
2. Select **API Keys**.
3. In **From**, enter the address you want emails to come from in the format `My Store <hello@validated-domain.com>`. The address must be on a domain that is already verified in your Postmark account.
4. Set **Provider** to **Postmark**.
5. Paste your Server API token into **Provider API key**.
6. Save the settings.<br>

From now on, all app emails will be delivered through your Postmark account, using your domain in the **From** address.

{% hint style="warning" %}
If the **From** domain is not verified in Postmark, sends will fail. Make sure DKIM and Return-Path are validated on the Postmark side first.
