White Labelling MX Records
White-labeled MX records are available exclusively on our ImprovMX Enterprise plans.
White-labeling lets you use your own branded MX records (e.g., mx1.piedpiper.com) instead of the default ImprovMX records (mx1.improvmx.com). Normally, a domain like customer.com would use mx1.improvmx.com as its MX record. With white-labeling, you supply a white-label domain (e.g., piedpiper.com), so the MX record becomes mx1.piedpiper.com . This is useful if you're reselling email forwarding services or want all your public DNS records to be consistently branded. It’s a cosmetic change only - forwarding will function exactly the same.
Instructions
In the ImprovMX dashboard for your custom domain (e.g., customer.com), go to the Custom Settings tab -> Whitelist Settings -> Enter your white-label domain (e.g., piedpiper.com).

Add CNAME records shown into domain registrars DNS settings.

In the DNS Settings for customer.com, apply the provided white-labeled MX and SPF records into the domain registrars DNS settings instead of the default ImprovMX records.

That's it! You can now use your own branded MX records for a fully white-labeled experience.
