# Sending Domain

By default, all emails are sent from the app's domain. This means your recipients will see **<mailer@giftcardfactory.app>** as the "From" address.

To improve email deliverability and build trust with your customers, you can configure your own store domain as the sending domain.

There are two ways to do this:

1. **Use a supported email delivery service**\
   Send emails through a third-party service like [**Postmark**](/misc/app-emails/sending-domain/postmark.md) or [**SendGrid**](/misc/app-emails/sending-domain/sendgrid.md).
2. **Verify ownership of your store domain**\
   [Add DNS records](/misc/app-emails/sending-domain/domain-ownership-validation.md) to your domain to validate ownership and authorize it for sending emails.

To update your sending domain, go to **Settings → App Emails Sending**:<br>

You'll see three options:

* **Default** — emails are sent from `mailer@giftcardfactory.app`. No setup required.
* **API Keys** — send via [SendGrid](/misc/app-emails/sending-domain/sendgrid.md) or [Postmark](/misc/app-emails/sending-domain/postmark.md) using your own account and API key.
* **DNS Validation** — send from your own domain after [validating ownership via DNS records](/misc/app-emails/sending-domain/domain-ownership-validation.md).

### Supported delivery services

To configure sending via a supported delivery service, you will need to add your API key in the app settings. Detailed instructions are available here:

* [SendGrid](/misc/app-emails/sending-domain/sendgrid.md)
* [Postmark](/misc/app-emails/sending-domain/postmark.md)

### Domain ownership validation

To validate ownership of your domain via DNS records, follow our instructions [here](/misc/app-emails/sending-domain/domain-ownership-validation.md).
