Using a Gmail or other free email account for business communication tells everyone you correspond with that you have not yet committed to your business at a basic level. It is a small detail that carries an outsized amount of weight. When a prospective customer receives a proposal from mike@gmail.com versus mike@yourbusiness.com, the second address communicates professionalism and permanence. The first communicates that you are still testing whether this is worth doing. Even if that is not the reality, that is the signal.
Setting up a business email address is straightforward and inexpensive. Google Workspace starts at six dollars per user per month and gives you a Gmail interface with your own domain, along with Google Drive, Docs, Meet, and Calendar under your business account. Microsoft 365 Business Basic costs around the same and gives you Outlook, Teams, SharePoint, and OneDrive. Both are reliable at the price point and integrate with the tools you are already likely using. The investment is minimal relative to what it communicates.
Your email domain should match your website domain exactly. If your website is at yourbusiness.com, your email should be @yourbusiness.com. Mismatches between email and website domains create confusion and can trigger spam filters when you send outreach. Set this up before you send your first business email, not after you have already built a contact list under a personal address. Migrating contact records and updating email signatures across platforms is an avoidable hassle.
The email address itself matters beyond just the domain. Use a professional format: your name, a role-based address like hello@ or info@ for general inquiries, or a combination. Avoid addresses that are cute or clever at the expense of being professional. The address is on every email you send, every business card you print, every form you fill out, and every directory listing you create. It becomes part of your brand identity in a way that most people underestimate when they are setting it up.
One additional benefit of Google Workspace or Microsoft 365 over free accounts is admin control. You can create and delete addresses, set up aliases, manage shared inboxes, and control who has access to what. When an employee or contractor leaves, you can transfer their email to another account or disable it entirely. That level of control is not available with personal accounts and becomes increasingly important as your team grows.
A business email address on your own domain is a ten-dollar-a-month decision that changes how every person you correspond with perceives you from the first message they receive.
