WHMCS ↔ Mailcow Integration Module

Turn Your WHMCS into a Full-Fledged Email Hosting Panel

This module was designed for hosting providers who want to deliver their own branded email service—with the same ease of use customers expect from the big players, but entirely under your control.

Because Mailcow is open-source, you can install it on your own server and own the entire infrastructure. The addon links WHMCS to Mailcow, automating domain provisioning and unlocking a clean, user-friendly Client Area where customers manage everything themselves.

In short: you become the email provider. Clients create, edit, and manage mailboxes without tickets or extra logins.

? What the Module Does

A smart connector between WHMCS and Mailcow.

Automatically provisions email domains in Mailcow whenever an order is approved.

Gives the Admin Area full visibility and control of all customer activity.

? Full Multilingual Support

This addon ships with translations for 26 WHMCS languages out of the box. When a client switches their language in WHMCS, the Mailcow panel instantly adapts—no manual editing required. You’re ready to serve customers worldwide with a seamless, localized experience right from day one.
