Wholesale Prices
Most Azure suppliers are charging 20-30x mark up per domain. Inboxing is setup as a wholesaler with room to negotiate for volume, so you can take advatange of lower rates, scale comfortably, and even resell the mailboxes (you can use our API to create your own platform!)
Simple Pricing
Domain Managers can buy mailboxes for domains they own to use in email campaigns (using our tenants). Platform Managers are advanced users who bring their own tenants and want to create/manage mailboxes within them. *99 mailboxes available to Platform Managers only.
