Email Styling
From WHMCS Documentation
All email messages sent to clients are wrapped in a customisable email design. By default, the email design is a cross platform compatible, mobile friendly, responsive email design featuring your company logo at the top and useful links in the footer.
You can customize this in the Mail tab at Configuration () > System Settings > General Settings or, prior to WHMCS 8.0, Setup > General Settings.
Admin notifications use a fixed design and cannot be customised.
Default Styling
The default styling is as follows:
