Best Enterprise Email Solution in India (2026): How to Actually Choose

Your choice normally falls into three broad categories:

XgenPlus supports sovereign cloud, private cloud, on-premise and hybrid/air-gapped approaches.

3. Security architecture

Don't stop at "Does it have spam filtering?"

Evaluate:

• MFA
• SSO
• encryption
• anti-spam and anti-malware
• authentication controls
• audit logs
• role-based administration
• archival
• retention
• DLP
• backup and disaster recovery
• endpoint security
• incident response
• administrative access controls

Key takeaway: The best enterprise email platform is the one whose security architecture matches your organization's risk profile not the one with the longest feature list.

Shared Cloud vs Private Cloud vs On-Premise: Which Should You Choose?

The right model depends on data sensitivity, regulatory requirements, internal IT capability, business continuity requirements, customization needs, and the organization's willingness to own infrastructure responsibilities.
