# Remove Domain

# Introduction

Mautic instances run on subdomains provided by us by default, but you can always add your own custom domain name and have the instance be served on it.

# Remove domain

To remove a previously configured custom domain name from an instance and revert to the original system subdomain, click on the gearbox icon next to it, and then clicking Remove Custom Domain.

Type remove in the field to confirm the removal and click Remove Domain.
