The many communications tools out there today are all about self-promotion—they want all users to be constantly aware that their tool is the one they're using. While tools like Microsoft Teams, Zoom, and GoToMeeting might provide services trusted by millions of users, their branding pushes their agenda, not yours. Your collaboration tools should make you and your team feel empowered, and not overwhelmed with loud logos, color schemes and watermarks.
The bottom line? Your sales, customer service, and client communication should be YOURS, not Zoom's.
