Business Email Hosting Reviews

Fastmail

Fastmail delivers 79% inbox placement, a clean privacy-respecting email experience, and genuinely good webmail at $5/seat/mo. No BAA, no free tier, but no Google data model either.

Best for: Small teams (1-15) who want a clean email experience without Google's data model, without Proton's complexity

Google Workspace

Google Workspace Business Starter delivers the highest inbox placement rate of any tested provider at 87%. At $7.20/seat/mo with no renewal price shock, it is the default recommendation for teams where deliverability and integrations matter.

Best for: Teams of 2-50 who need best-in-class deliverability and ecosystem integrations

Microsoft 365

Microsoft 365 delivers 82% inbox placement, desktop Office apps, and BAA signing for HIPAA. The July 2026 price rise makes the Google Workspace comparison tighter — but if your team lives in Word and Excel, M365 remains the only serious option.

Best for: Teams where Word, Excel, and PowerPoint are daily tools; compliance verticals needing BAA

Proton Mail Business

Proton Mail Business delivers zero-access encryption, Swiss jurisdiction, and 76% inbox placement at $7.99/seat/mo. The encryption moat is real — but E2EE only works Proton-to-Proton, and HIPAA BAA is explicitly not available.

Best for: Privacy-conscious founders, EU-residency requirements, teams handling sensitive client data outside HIPAA scope

Zoho Mail

Zoho Mail delivers 71% inbox placement and the most credible free tier in business email. At $3/seat/mo (Workplace Standard) it saves 42% vs Google Workspace at 30 seats. The honest catch: integration depth and IPR are both lower.

Best for: Cost-optimising 30+ seat teams, solopreneurs on a zero budget (Zoho Free), teams with a thin integration stack
