AppsFlyer? Email Archiving

SKAN and postback measurement for mobile ad campaign attribution.
AppsFlyer primarily focuses on mobile attribution and marketing analytics, not on email archiving workflows. It can support retention of marketing event data and auditability for campaign performance, but it does not provide an email archiving system for storing, indexing, and searching message content.

Prioritize centralized retention and policy management that administrators can tune with supervision and audit-friendly reporting. Mimecast Email Archive emphasizes retention and policy management designed for audit-ready governance, and Proofpoint Email Archive uses centralized archive management with policy-driven retention and audit-ready reporting.
Archive search that indexes and accelerates discovery

How to Choose the Right Email Archival Software
Pick the archive that matches your mail platform, your legal hold and eDiscovery workflow depth, and your governance maturity.
Start with your email ecosystem and ingestion sources
If your environment is primarily Microsoft 365 with hybrid or Exchange requirements, Mimecast Email Archive and Barracuda Email Archiving support journaling-based capture from Microsoft 365 and on-premises Exchange environments. If you want a native Microsoft admin experience, Microsoft Exchange Online Archiving uses archive mailboxes plus retention tags and policies managed through Exchange and Purview. If your organization standardizes on Google Workspace, Google Vault archives Gmail and other Workspace content with legal holds and retention rules inside the Google admin workflow.
Verify legal hold depth and eDiscovery-style search and retrieval
For regulated teams that need investigations and discovery exports, ensure the product includes legal hold workflows and eDiscovery-style retrieval rather than basic search. Mimecast Email Archive and Proofpoint Email Archive both emphasize legal hold with eDiscovery search across retained emails. Global Relay Email Archive adds chain-of-custody oriented review workflows, and OpenText Email Archive supports legal hold style workflows with defensible records.
Assess governance capabilities and audit-ready reporting needs

If you need defensible handling based on sensitivity classification, IBM Security Guardium Data Protection for Email ties controls to sensitivity and applies governance and auditability across email data handling. If your compliance posture is built around records management processes, OpenText Email Archive includes defensible records workflows.
Match the archive experience to how end users will retrieve content
If users need direct mailbox-like retrieval for routine access, Microsoft Exchange Online Archiving provides an archive mailbox inside Exchange Online for seamless administration. If your investigators rely on search workflows for internal review and regulator-ready export, tools like Google Vault, Global Relay Email Archive, and Mimecast Email Archive focus on search, supervision, and discovery export processes. If end users will not actively retrieve content often, Global Relay Email Archive and Proofpoint Email Archive still support discovery exports and review workflows for governance teams.
Validate setup complexity against your IT and compliance staffing model

Common Mistakes to Avoid
Common buying errors come from underestimating governance setup work, mismatching the archive to the mail platform, and choosing products that do not actually archive message content.
Choosing a tool that does not provide true email message archiving and searchable retrieval
AppsFlyer email archiving is optimized for mobile attribution and event tracking, and it does not provide an email archiving system for storing, indexing, and searching message content. For actual email retention and investigation workflows, use tools like Mimecast Email Archive or Google Vault.
Underestimating policy and legal hold configuration effort for compliance-grade archiving
Mimecast Email Archive and Proofpoint Email Archive can require specialist time for configuration and policy setup because they deliver audit-ready governance and eDiscovery-style workflows. OpenText Email Archive and Global Relay Email Archive also demand setup and governance attention for legal hold and review processes.
Assuming mailbox-based retention alone will cover legal hold and discovery needs
Proofpoint Email Archive and Mimecast Email Archive emphasize centralized archive management and supervision workflows so administrators can enforce retention and discovery without relying only on mailbox-based retention settings. Microsoft Exchange Online Archiving includes legal holds and eDiscovery integration, but it is not a standalone archiver for non-Exchange sources.
Ignoring ingestion coverage across Microsoft 365, Exchange, or Google Workspace sources
Barracuda Email Archiving and Mimecast Email Archive support journaling capture from Microsoft 365 and Exchange environments to keep retention consistent across mail flows. Google Vault is designed for Google Workspace mail and chat, so it is not a fit when your primary requirement is hybrid Microsoft and on-premises Exchange ingestion.
