Self-Hosted Email Cost Calculator
Per-seat email pricing looks cheap until you multiply it by every employee and every year. Type your numbers below. The self-hosting defaults are what one real migration actually cost, not a vendor estimate.

Break-even:
What this leaves out
- Migration labour and user training. In our migration the slow part was DNS and DKIM mistakes caught by the first small department, not the data move.
- The cloud bundle's other apps (video calls, office suite, 1 TB of drive). If your users need them, price that separately.
- Deliverability work on a fresh IP range, and the admin hours above are an estimate you should replace with your own.
