Private Cloud Email Infrastructure & Data Sovereignty Migration

The client relied on a third-party email provider with opaque data handling practices, escalating subscription costs, and rigid limits on mailbox creation and storage allocation.

• Concerns over email content privacy and third-party data access
• Rising per-user licensing and storage charges
• Limited flexibility in spam control and mailbox policies

The solution needed to ensure security, reliability, and operational continuity while transitioning away from a vendor-managed service.

• Email availability could not be disrupted during migration
• The client required full ownership of data, backups, and access policies
• The system needed to be maintainable without vendor lock-in

Provisioned a dedicated AWS environment fully owned by the client and deployed a self-hosted email platform using Mailcow, enabling complete control over infrastructure, policies, and costs.

• Created and configured a client-owned AWS account for full infrastructure ownership
• Deployed Mailcow to manage SMTP, IMAP, spam filtering, and DKIM/DMARC policies
• Defined custom mailbox quotas, user limits, and spam control rules

The client gained complete sovereignty over their email data while reducing long-term costs and improving operational flexibility.

• Eliminated dependency on third-party email vendors
• Reduced recurring subscription and storage costs
• Improved confidence in data privacy, backup control, and compliance readiness

Built on a secure and scalable cloud foundation with an emphasis on transparency and control.

• AWS infrastructure fully owned and managed by the client
• Mailcow email platform with integrated spam and security controls
• Custom backup strategy for mailbox data and configuration
