Many companies spend time and money on things like business cards yet overlook proposal templates, invoices and email signatures — items that prospects see more frequently. When an employee customizes an email template with unusual designs or fonts, it can contradict an expensive and serious business card – and convey a far different impression to the customer.
Each element in your corporate identity should use the same fonts, colors, and layout. The design itself may not be incredibly important unless you’re in a creative field, but consistency and professionalism make an impression. In many cases it may be a first impression, so why not make a good one?
