// THE_CHALLENGE

480 staff were split across personal webmail and a decaying legacy server. Client mail was landing in spam and leaving with employees.

// THE_OUTCOME

Every mailbox now sits on the company domain with verified deliverability, and inbox placement is monitored continuously.

// WHAT_WE_BUILT

  • Domain-branded mailboxes with shared inboxes and aliases
  • SPF, DKIM and DMARC configured and monitored
  • Staged migration with zero mailbox downtime
  • Offboarding policy so company knowledge stays company-owned
