BrandMail®, created by BrandQuantum, is an innovative software tool that integrates seamlessly with Microsoft Outlook, enabling all employees within the organization to automatically generate emails that consistently reflect the brand through an easy-to-use toolbar that grants access to brand guidelines and the most current pre-approved materials.

These signatures are secure and managed from a central location, providing peace of mind regarding their integrity. Notably, users can view their signatures, banners, and surveys when composing, replying to, or forwarding emails. Unlike other solutions, BrandMail does not redirect emails through external servers nor does it modify the rules within your exchange environment, functioning entirely within Microsoft Outlook.
