Why businesses leave Google Workspace & cPanel for Kosh
Setting up business email used to mean either paying an escalating per-seat monthly tax or wrestling with brittle DNS records. Kosh eliminates both:
Per-Seat Pricing Bloat
Google Workspace and Microsoft 365 charge $7.20 to $18/user every month. A 5-person team pays $430+/year just for basic mailboxes and aliases that should be free.
Brittle DNS & Spam Placement
SPF syntax errors, missing 2048-bit DKIM keys, and unaligned DMARC records silently divert your critical proposals and invoices to spam folders.
Ad Mining & Data Profiling
Big tech platforms scan corporate correspondence to build user advertising profiles and train AI models. Kosh enforces zero-access AES-256 storage.
Once your domain is live:Email at the speed of chat.
Traditional email buries communication under nested > > > quotes and bloated signature blocks. Kosh formats threads like a sleek messenger—while your recipients always receive standard, professional RFC emails in Gmail or Outlook.
