# How to install license keys

There are two types of license keys provided for Jira Email This Issue (JETI):

* Marketplace License Key
* Vendor License Key

{% hint style="info" %}
**Note**: Sales for Server licenses has ended, but the procedure is still applicable for DC licenses.
{% endhint %}

## Marketplace License Key <a href="#howtoinstalllicensekeys-marketplacelicensekey" id="howtoinstalllicensekeys-marketplacelicensekey"></a>

Obtain your marketplace license key by purchasing the license in the [Atlassian Marketplace](https://marketplace.atlassian.com/plugins/com.metainf.jira.plugin.emailissue).

{% hint style="info" %}
**Note**: Marketplace license keys are sent to you by Atlassian. No interaction with the Vendor (META-INF) is required in order to receive your key.
{% endhint %}

Jira has a built-in app manager. Marketplace License Keys must be saved there.

Go to **Administration** --> **Manage apps** then choose **ATLASSIAN MARKETPLACE** --> **Manage apps**.

## Vendor License Key <a href="#howtoinstalllicensekeys-vendorlicensekey" id="howtoinstalllicensekeys-vendorlicensekey"></a>

Before JETI was available in the Marketplace, we sold license keys directly to customers. These are called Vendor License Keys.  If you have purchased a vendor key, you must have interacted with us and you must have received your key in an email from us, the vendor.

In this case, you have a Vendor License Key that must be installed differently.

Go to **Administration** --> **Manage apps** then choose **ATLASSIAN MARKETPLACE** --> **Manage apps**.
