imapsync vs Zoho Mail

imapsync is an IMAP transfer tool for migrating or backing up mailbox accounts. Its command-line software makes incremental, recursive transfers, and a stopped transfer can be restarted without generating duplicates. The software runs on Windows, Mac OS X and Linux, with listed compatibility including Gmail, Office 365, Exchange, Dovecot and Zimbra. The online service offers free mailbox syncs below 3 GB; buying provides unlimited syncs of any size. Buyers also receive a visual interface for installation on a Linux server, though that interface does not yet work on Windows. Staged and tenant-to-tenant moves are supported, including for Microsoft 365 and Google Workspace. The software-only plan is €72 as a one-time purchase; professional support is €144, paid once, as is the Imapsync + support plan. There is no trial version, and purchases carry a 30-day money-back guarantee. The tool cannot migrate contacts or calendars, maintain two-way synchronization between active accounts, or transfer messages to or from a local directory.

Zoho Mail provides custom-domain email hosting for businesses, with access through web, desktop and mobile apps. The free plan supports one domain and up to five users, each with 5 GB of mail storage; it excludes IMAP, POP and Active Sync. Paid plans start at $1/user/mo when billed annually, and a 15-day trial is listed. Security features include TLS, S/MIME and AES-256 encryption at rest, while administrative controls include role-based access, custom security policies, audit logs and eDiscovery. The service lists spam and phishing blockers, and Zia can draft replies and summarize long email threads. Zoho Mail MCP connects the service to AI apps. A migration tool can transfer emails, contacts and calendars from Google Workspace, Microsoft 365 or IMAP providers. Mobile apps combine email, calendar, contacts and files. Zoho says the service is GDPR compliant and has ISO/IEC 27001 and SOC 2 Type II certifications. Paid plans include 24×7 support by email, phone and live chat; the pricing comparison lists a 99.9% uptime guarantee for its plans.
