A professional business email address, often assumed to be a paid necessity costing upwards of $22 per user per month, can actually be secured for free with custom domain support for teams of up to five. Securing a professional business email address for free with custom domain support for teams of up to five contradicts the widespread belief that such features demand a significant monthly subscription, potentially saving small businesses over $1300 annually. Many businesses, especially startups, overpay for email services when free, feature-rich alternatives exist. For instance, Google Workspace Business Plus costs $26.40 per user per month, or $22 with a 1-year commitment, according to Google Workspace.
