Shared Inboxes and Aliases Done Right
The 60-second version
Shared inboxes (e.g., support@yourbusiness.com) and aliases (e.g., sales@ forwarding to multiple users) streamline communication but can create security risks if misconfigured. Proper setup ensures accountability, prevents data leaks, and maintains compliance.
What this solves (in real business terms)
- Team collaboration: Multiple users can manage shared emails (e.g., support, sales).
- Professionalism: Present a unified brand (e.g.,
contact@instead of personal emails). - Security: Prevent unauthorized access or auto-forwarding to external addresses.
- Compliance: Meet requirements for access control and audit logs.
What it costs (honest ranges)
- Shared inboxes: Often included with email hosting (e.g., Google Workspace, Microsoft 365).
- Aliases: Free for basic forwarding; advanced routing may cost $5–$20/month.
- Audit tools: $10–$50/month for monitoring shared mailbox access.
- Consulting: $1,000–$5,000 for setup and training.
What can go wrong
- Over-sharing: Too many users with access to sensitive emails.
- Auto-forwarding risks: Emails leaked to external addresses.
- Lack of accountability: No logs for who accessed/deleted emails.
- Compliance gaps: Shared inboxes violating industry regulations.
Vendor questions (copy/paste)
- "Can you restrict shared inbox access to specific teams?"
- "Do you log all actions (e.g., reads, deletes) in shared mailboxes?"
- "How do you prevent auto-forwarding from shared inboxes?"
- "Can we set retention policies for shared inbox emails?"
- "What’s your uptime SLA for shared mailbox availability?"
Minimum viable implementation
- Limit access: Only grant permissions to users who need them.
- Disable auto-forwarding: Prevent emails from being sent outside your domain.
- Enable logging: Track who accesses shared inboxes.
- Set retention policies: Automatically archive or delete old emails.
- Train users: Teach teams how to use shared inboxes securely.
When to hire help
- Complex setups: Multiple shared inboxes with granular permissions.
- Compliance audits: Ensure shared inboxes meet industry standards.
- Security reviews: Detect misconfigurations or risks.
- Tool deployment: Configure advanced monitoring or automation.
