Linking Your Domain

Note: This addon is available on selected standard profiles and in any custom profile that costs more than a certain fixed price per month.

In the "Manage Email" screen (which can be found in the main server screen) you can connect your domain to the Postmark addon.

Once you enter your domain and connect you'll be shown DNS records information. You need to add/create them in your domain DNS interface for verification. To forward incoming emails on your doamin to your email inbox, check this ImprovMX intro guide.

The verification happens automatically and once that's done you'll see the credentials and the API key of Postmark, which you can use to send emails.

Note: Some domain providers auto-append your domain to the host field address. In that case, you need to omit the trailing "domain.tld" part from the host value.

A tip: If yours is a WordPress site, all you need to do is to install the Postmark WP plugin and input the credentials into the plugin. That's all. The WP Postmark plugin then takes care of sending emails.

That's it.
