# SMTP provider configuration

{% hint style="info" %}
You have to activate your SMTP provider so Zitadel can use it to send your emails. Only one provider can be active.
{% endhint %}

To access the SMTP Provider management panel, navigate to Zitadel by selecting **Organization Settings** from the **profile button** located at the bottom left.

To ensure you only send the emails from domains you own, you need to add a custom domain to your instance. In order to configure a custom domain, go to the ZITADEL [customer portal](https://zitadel.cloud/) -> Default Settings -> SMTP Provider.

To configure your custom SMTP, you need to fill in the following fields:

* Sender email address
* Sender name
* Enable or Disable Transport Layer Security (TLS)
* Host
* User
* SMTP Password

While you create/update a SMTP provider, you can test your SMTP configuration.

In the SMTP providers table, you can hover over a provider's row to display buttons that let you activate or deactivate a provider, test your SMTP settings, and delete a provider.&#x20;
