# Custom SMTP

> Custom SMTP lets you send booking confirmation emails, reminders, and workflow notifications from your own email server instead of lunacal's default mailer. 

Your guests and clients will see your domain in the sender address, keeping your brand consistent.

> **Note:** Custom SMTP is available on **Enterprise plan**. If the section does not appear in your settings, check your current plan.

## Disconnecting Custom SMTP

Click the **Delete** button in the SMTP Configuration section to disconnect your SMTP server.

**What happens when you disconnect:**

* **Emails stop sending** — all workflows that were created or updated while SMTP was connected will stop sending emails.
* **Workflows are disabled** — those workflows will be disabled for all event types they are attached to.
* **Re-verification required** — you will need to re-verify the email content of these workflows before they can send again.

Reconnecting SMTP will not automatically re-enable disabled workflows. You will need to re-attach them to your event types manually.
