When choosing an email hosting solution for your business, you’ll often encounter two fundamentally different philosophies: email-first providers who excel at one thing, and productivity suite companies that bundle email with dozens of other tools. Today, we’re comparing Greatmail and Zoho Mail—two providers that represent these distinct approaches to business email hosting.
Why This Comparison Matters
While many businesses automatically assume they need a full productivity suite, the reality is that email remains the backbone of business communication. Understanding whether you need a specialized email hosting provider like Greatmail or a suite-based approach like Zoho Mail can save you thousands of dollars annually while delivering better performance for your actual needs.
Zoho Mail: The Freemium Gateway to a Massive Ecosystem
The Suite Strategy Approach
Zoho Mail isn’t just an email service—it’s the entry point to Zoho’s sprawling ecosystem of over 45 business applications. This “freemium to enterprise” model offers a compelling free tier for up to 5 users, but understanding the full picture requires looking beyond the initial price tag.
Pricing Structure and Hidden Complexity
Zoho’s pricing appears straightforward at first glance: free for up to 5 users, then $1 per user per month for the Mail Lite plan. However, this simplicity masks several important considerations:
- Storage Limitations: The free plan provides only 5GB per user, while paid plans start at 10GB
- Suite Integration Strategy: Zoho’s business model encourages users to explore their broader ecosystem of applications as their needs grow
- Feature Restrictions: Many advanced business features require upgrading to higher tiers or adopting additional Zoho applications
The challenge many businesses face is what we call “ecosystem expansion”—starting with simple email needs and gradually being encouraged to adopt more applications and higher-tier plans as requirements grow.
Core Features and Capabilities
Zoho Mail provides solid email functionality with some notable strengths:
- Multi-Platform Support: Excellent mobile apps and desktop clients
- Integration Ready: Seamless connections to other Zoho applications
- Collaboration Tools: Built-in chat, notes, and basic calendar functionality
- Security Features: Two-factor authentication and encryption standards
However, businesses often discover that accessing advanced features requires purchasing additional Zoho applications or upgrading to more expensive tiers.
Greatmail: Email Hosting Specialization at Its Best
The Email-First Philosophy
Greatmail takes a fundamentally different approach: doing one thing exceptionally well. With over 20 years of experience in email hosting, Greatmail focuses exclusively on providing reliable, business-class email without the complexity or cost of unwanted productivity features.
Transparent Pricing for Predictable Budgeting
Greatmail’s pricing model eliminates surprises:
- Standard Plans: $1.95 per mailbox per month (10GB) or $2.95 per mailbox per month (25GB)
- Groupware Options: $3.95 per mailbox per month (10GB) or $4.95 per mailbox per month (25GB) with advanced calendar/contact features
- No Hidden Fees: What you see is what you pay, with no pressure to upgrade to unneeded applications
This per-mailbox approach means each user receives dedicated resources and guaranteed storage, making it easy to predict costs as your team grows.
Business-Class Features Without the Bloat
Greatmail’s feature set is carefully curated for business email needs:
- Advanced Webmail: Professional Roundcube interface with Outlook-style layout for Standard plans; upgraded SoGo webmail for Groupware users
- Enterprise Security: Built-in spam filtering, antivirus protection, and SSL/TLS encryption
- Groupware Capabilities: CalDAV/CardDAV support and ActiveSync for Groupware edition users, enabling seamless calendar and contact synchronization
- Migration Support: Professional assistance for moving from other email providers
- Reliable Infrastructure: 99.9% uptime guarantee with redundant systems
- Domain-Level Control: Flexible storage allocation and administrative controls
The key advantage is that these features come standard without requiring additional purchases or suite upgrades.
The Critical Differences: Free vs Business-Focused
Understanding Zoho’s Free Tier Limitations
While Zoho’s free tier is attractive, it comes with several business limitations:
- 5-User Maximum: Growth beyond 5 employees requires immediate paid upgrades
- Limited Storage: 5GB per user may be insufficient for businesses with document attachments
- Branding Restrictions: Free accounts include Zoho branding in email signatures
- Support Limitations: Free users receive community support rather than business-class assistance
Greatmail’s Minimum Service Requirements
It’s important to note that Greatmail requires a minimum of 5 mailboxes to establish service, making the smallest starting plan $9.75 per month ($1.95 × 5 mailboxes). This business-focused approach reflects Greatmail’s positioning as a provider for established businesses rather than individual users or very small teams.
Greatmail’s Business-First Approach
Greatmail’s model assumes you’re running an established business from day one:
- Minimum Service Level: 5-mailbox minimum ensures dedicated business-class resources and support
- Professional Support: Business-class support included with all plans
- Custom Branding: Your domain, your brand—no third-party advertising
- Dedicated Resources: Each mailbox receives guaranteed storage and performance
Data Privacy and Business Model Differences
Zoho’s Ad-Free Commitment
Zoho Mail delivers an impressive ad-free email experience across all plan tiers, including their generous free offering. This commitment to clean, professional email without advertising creates a genuine business-class experience even for free users:
- No Email Advertising: Zoho maintains a completely ad-free email environment
- Professional Experience: Free users enjoy the same clean interface as paid subscribers
- Suite Integration: Seamless connectivity with other Zoho business applications when needed
Greatmail’s Privacy Commitment
As a paid-only service, Greatmail’s privacy approach is straightforward:
- Email-Only Focus: Your email data isn’t integrated across dozens of applications
- Business Compliance: Clear data handling policies designed for business requirements
Migration and Setup Complexity
Zoho Mail Implementation
Setting up Zoho Mail involves several considerations:
- DNS Configuration: Standard MX record changes required
- Suite Decision Points: Immediate decisions about which additional Zoho apps to implement
- Integration Planning: Determining how email fits into broader Zoho ecosystem usage
Greatmail’s Streamlined Approach
Greatmail migrations focus purely on email:
- Professional Migration Support: Assisted transfers from existing email providers
- Simple DNS Setup: Clear instructions for MX record configuration
- Email-Only Focus: No decisions required about unrelated productivity applications
Performance and Deliverability Comparison
Zoho Mail’s Track Record
Zoho Mail provides reliable email delivery with some notable characteristics:
- Global Infrastructure: Multiple data centers provide good performance worldwide

Frequently Asked Questions
Yes, Zoho Mail offers a genuinely free tier for up to 5 users with 5GB storage per user. This includes core email functionality, calendar, contacts, and an ad-free experience. However, businesses should understand the limitations: no IMAP/POP access on the free plan, basic support only, and storage constraints that may require upgrades as email usage grows. The free tier is excellent for startups and very small teams testing professional email, but growing businesses often need to upgrade to paid plans for advanced features and increased storage.
Zoho Mail has no minimum user requirement and offers free service for up to 5 users, making it ideal for solo entrepreneurs or tiny teams. Greatmail requires a minimum of 5 mailboxes, with pricing starting at $9.75 per month total ($1.95 per mailbox). While this means a higher entry cost, the minimum requirement ensures each business receives dedicated resources and professional-grade support from day one.
Both providers support Outlook, but with different configurations. Zoho Mail’s free tier only supports webmail access, requiring a paid upgrade for IMAP/POP/SMTP protocols needed by Outlook. Greatmail includes complete Outlook support across all plans, with detailed setup instructions for IMAP, POP3, and SMTP. Additionally, Greatmail’s Groupware edition offers ActiveSync support for enhanced Outlook integration, including calendar and contact synchronization that works seamlessly with Outlook’s native features. Zoho’s paid plans also include sync for calendars and contacts.
For startups with very limited budgets and 5 or fewer team members, Zoho Mail’s free tier provides excellent value with professional email functionality and no monthly costs. This allows startups to establish professional email addresses while preserving cash flow for other business priorities. However, startups planning to grow beyond 5 employees or needing advanced features like IMAP access should consider Greatmail’s transparent pricing model, which eliminates surprise upgrade costs and provides predictable scaling as the team expands. The choice depends on current team size, growth timeline, and technical requirements.
CalDAV/CardDAV support enables seamless calendar and contact synchronization across multiple devices and email clients, which is valuable for businesses using various devices and applications. Both providers support calendar and contacts synchronization. Zoho Mail includes these sync capabilities across all paid plans, while Greatmail’s Groupware edition offers enhanced implementation with SoGo webmail interface for advanced calendar and contact management and full support for CalDAV/CardDAV and ActiveSync protocols. If your team uses multiple devices, desktop email clients like Outlook or Thunderbird, or mobile devices that need calendar/contact sync, CalDAV/CardDAV support becomes important for maintaining productivity and avoiding manual data entry across platforms.
Both providers offer migration assistance, but with different approaches. Zoho Mail provides self-service migration tools and documentation for transferring from major providers like Gmail and Outlook, though free tier users have limited support options. Greatmail includes professional migration assistance with phone and email support for account administrators, helping businesses transfer from existing email providers with personalized guidance throughout the process. For businesses concerned about email continuity during migration or those with complex setups, Greatmail’s hands-on migration support can be invaluable, while technically savvy teams may find Zoho’s self-service tools sufficient.
The Bottom Line
The choice between Zoho Mail and Greatmail fundamentally comes down to your business size, budget, and philosophy about email hosting.
For small businesses with limited budgets, Zoho Mail offers exceptional value that’s hard to beat. The combination of a truly free tier for up to 5 users, ad-free experience, and solid email functionality makes it an outstanding choice for startups, consultants, or small teams just getting established. The ability to grow into Zoho’s integrated suite as your business expands provides a clear growth path without vendor switching.
For established businesses with 5 or more employees, Greatmail’s specialized approach delivers superior value through predictable costs, dedicated resources, and email-focused expertise. The transparent pricing, professional migration support, and advanced groupware capabilities (CalDAV/CardDAV, ActiveSync, SoGo webmail) often prove more cost-effective for businesses that know they need excellent email hosting without productivity suite complexity.
Consider your current team size, email usage patterns, and whether you truly need the additional applications that come with suite-based approaches. Sometimes, doing one thing exceptionally well—like email hosting—delivers better results than managing dozens of integrated tools you may never fully utilize. Conversely, if you’re a small team looking to minimize expenses while maintaining professional email capabilities, Zoho’s free tier provides genuine business-class features that can support your growth.
