High-engagement recipients open emails and scroll down as they read. This should be done for almost all emails that are opened, as long as the content is not longer than the page. If a recipient takes an email from spam and goes out of their way, it is telling the inbox provider that they made a mistake. Inbox providers will be able to tell if you move an email from the promotions folder into the primary inbox that you don't agree with their sorting criteria. It and other similar emails should go directly to the primary mailbox. It shows that the recipient is interested in your email content. The inbox provider can interpret this as "This email is extremely important, please do not send it to spam."

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. With this solution, email signatures are crafted according to your branding requirements, ensuring a uniform appearance regardless of the device or platform used to view them. 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. By utilizing BrandMail, organizations can turn every email into a branding opportunity while also reducing the security vulnerabilities linked to the manipulation of HTML signatures, thereby enhancing both brand consistency and cybersecurity. This not only streamlines communication but also reinforces the brand identity across all employee interactions.
