Our verdict on Greatmail

Greatmail provides paid business email hosting for startups, small and medium-sized businesses, and enterprise customers. It supports custom domains, multiple-domain hosting, IMAP, POP3, SMTP, and webmail with folders, search, filters, and signatures. Spam and virus filtering, aliases, forwarding, SPF, DKIM, and DMARC support cover the core requirements for managed business mail. Mailbox migration assistance is also available, making the service suitable for organizations moving existing email accounts.

The offering is divided between Standard and Groupware editions, with 10 GB and 25 GB mailbox options. Standard Edition focuses on email hosting, including webmail, filtering, and access through common mail protocols. Groupware Edition adds calendar and contact synchronization, plus calendar and contact sharing. The published starting price is 1.95 per mailbox, and plans require a five-mailbox minimum. Businesses should compare the two editions based on whether shared calendars and contacts are required rather than treating Groupware as a default upgrade.

Greatmail fits established email clients and mobile mail apps, including Microsoft Outlook, Thunderbird, Apple Mail, Android mail apps, and iOS mail apps. Access is also available through the web, iOS, and Android platforms, with mobile access described through third-party apps. This makes it a reasonable choice for teams that want conventional mailbox access across devices and control over domain authentication records. Organizations that need only core email can choose Standard, while teams requiring synchronized and shared calendars or contacts should choose Groupware. A different service may suit businesses seeking a free tier or calendar functionality across every plan.
