Dear Super Admin,<br/><br/>
    I am writing to inform you that you have a new custom domain linking request for <b>{instance_name}</b>. 
    <br/>
    Tenant ID: {instance_slug}<br/>
    Custom domain: {instance_custom_domain}<br/>
    Customer: {contact_firstname} - {contact_email}
    <br/><br/>
    You can access the instance directly from <b>{admin_url}saas/companies/edit/{instance_id}</b>.
    <br/><br/>
    Best regards,<br/>
