# SendGrid

SendGrid sends your app emails through your own [SendGrid](https://sendgrid.com/) account. You'll need a SendGrid account with a verified sender identity (single sender or authenticated domain) before you start.

### 1. Create a SendGrid API key

In your SendGrid dashboard, navigate to **Settings → API Keys**.

Click **Create API Key** and select **Restricted Access** (or **Custom Access**, depending on your account version).

Under **Access Details**, give the key **Full Access** for **Mail Send**, then click **Create & View**. Copy the API key — you won't be able to see it again.

### 2. Add the API key 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 authenticated in your SendGrid account.
4. Set **Provider** to **Sendgrid**.
5. Paste your API key into **Provider API key**.
6. Save the settings.<br>

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

{% hint style="warning" %}
If the **From** domain is not authenticated in SendGrid, sends will fail. Make sure domain authentication is set up on the SendGrid side first.
{% endhint %}
