Setting up a business email address on your domain has lots of branding and administrative advantages. Think of your business email as a marketing tool – it’s likely the first impression your clients will get from you when you initiate contact. Using your domain in the email address means prospects and customers have an immediate reference point as to who you are and can search for your business online. By contrast, sending emails from a free email service such as Google or Yahoo will diminish your credibility and professionalism.
Even businesses with dedicated on-site IT staff have seen the wisdom of moving their email service. The advantages include per-person cost averages, cutting-edge security, cheap email storage, and simple ease of connectivity and deployment. While these advantages hold true for most organizations, there are not only exceptions but also hidden "gotchas" you should look for before selecting a cloud-hosted email provider.
