MailArchiva vs ZL Unified Archive

MailArchiva is an email archiving service for organizations that need e-discovery, forensic investigation and compliance capabilities. It can search email and attachment contents, produce reports, bulk-export archive data, restore messages to mailboxes and export search results to CSV. Retention policies, legal holds, audit trails and tamper-proof archive data support governance. MailArchiva Cloud lists compatibility with Office 365, Google Workspace, Microsoft Exchange, Zimbra, Kerio Connect, SmarterMail, MDaemon and IBM Lotus Domino. The service runs on Linux and Windows and is also listed for web, API and self-hosted use. Cloud archives can be hosted in California or Amsterdam; the listed hosting certifications differ by region. Cloud storage includes three-way redundancy and ten years of archiving from service commencement, with a 99.95% uptime SLA advertised. A free plan and 30-day trial are listed. Cloud trial users cannot import historical data, and trial data is erased unless a subscription order arrives before the trial ends.

ZL Unified Archive consolidates archived and in-place unstructured content in a repository for archiving and governance. It supports email, files, Microsoft Teams, Microsoft 365, SharePoint, social media, instant messages, legacy databases and archives, and formats including CSV, XML, and JSON.

For Teams, the system captures files, messages, reactions, and surrounding content for policy application, review, and selective archiving. Records management offers more than 20,000 manual and automated classifications, configurable lifecycle policies, an audit log of document actions, and one-click legal holds. eDiscovery capabilities include early case assessment, search and culling, hierarchical tagging, email threading, and customizable workflows within the archive.
