Zoho Mail Free Plan Limits: What to Do After 5 Users

A business email solution should be evaluated for account protection, administrator controls, spam filtering, phishing defence, encryption, logging, and recovery capabilities. The exact features available depend on the provider and subscription.

What should your email security checklist include?

• Multi-factor authentication (MFA): Require additional verification for administrator and employee accounts where supported.
• SPF, DKIM, and DMARC: Configure domain authentication to reduce opportunities for unauthorised senders to impersonate your domain.
• Phishing and malware filtering: Assess how the provider detects suspicious links, malicious attachments, and impersonation attempts.
• Transport security: Check support for TLS and, where appropriate, stronger policies such as MTA-STS and TLS reporting.
• Account lifecycle management: Disable former employees' access promptly and transfer business-critical messages and ownership appropriately.
• Backup and recovery: Understand retention, deleted-message recovery, backup coverage, and disaster-recovery procedures.
• Administrator visibility: Review audit logs, access controls, and the ability to investigate suspicious activity.

These measures address different risks. For example, SPF, DKIM, and DMARC help with domain authentication, but they do not independently prevent every phishing attack or compromised account.

Where does SpamJadoo fit into the email security architecture?

SpamJadoo is relevant when an organisation needs an additional layer of email filtering beyond its mailbox provider's built-in controls. An email security gateway can evaluate incoming messages using techniques such as sender-reputation checks, DNS-based blocklists (DNSBLs), reverse DNS, authentication results, and spam or malware detection.

In an SMTP gateway deployment, some unwanted messages may be rejected during the SMTP transaction rather than accepted for later filtering. The actual behaviour depends on the gateway's configuration and detection results.

For startups, the first priority should be to secure user accounts and configure domain authentication correctly. As email volume and exposure grow, an organisation can assess whether an additional secure email gateway is justified.
