How InboxKit billing works
InboxKit doesn't sell plans. You top up a wallet and pay per mailbox or per Azure domain, and each item renews on its own date. There are no slots, no minimums and no setup fees. Cards are accepted, and enterprises can request NET-30 invoicing.
That makes the price easy to work out: number of mailboxes × price for your billing term. A 50-mailbox Google setup on monthly billing costs $150.00/month at list price, or $127.50 with GET50.
What every mailbox includes
- A dedicated admin panel for each domain, with 2FA
- Automatic SPF, DKIM, DMARC and MX setup
- US IP addresses
- 24+ sequencer integrations, plus API access with webhooks
- Unlimited team members and workspaces
- Email and chat support, and real-time monitoring
