How do I set up professional business email affordably?

Google Workspace ($7/user/mo) is the standard — Gmail interface, shared drives, and video meetings. Microsoft 365 ($6/user/mo) is better if your team lives in Excel and Word. Zoho Mail ($1/user/mo) is the budget option with solid features. Custom domains (you@yourbusiness.com) cost $10-15/year through any registrar. Avoid free email providers for business — it hurts credibility and deliverability.
