Facts checked 9 Oct 2026

In short

The Standard mailbox costs $10.00 per mailbox a month on a monthly commit, so 5 mailboxes cost $50 a month^1,2.
Each mailbox has 25 GB of storage, and the page lists no yearly price¹.
Admins can set two-step sign-in to Required, Optional or Off for each domain⁶.
Shared calendars and contacts come only with the Email Plus add-on, +$2.00 per mailbox a month¹.
A 14-day free trial is offered, with no long-term contract¹.

Rackspace Email suits small teams that want to pay month to month and reach support by phone¹. Its mailboxes hold 25 GB, and admins can require two-step sign-in per domain^1,6. The catch is price: $10 per mailbox is high for 5 users, and calendars need a paid add-on¹.

Best for: Small teams that want month-to-month billing and phone support.

Standard mailbox1 mailbox	$10.00/mailbox/month^1,2	$10	25 GB mailbox, 30 GB file storage, monthly commit
Standard with Email Plus1 mailbox	+$2.00/mailbox/month on top of Standard^1,2,13	$12	Adds shared calendars and contacts, ActiveSync and Mobile Sync

Rackspace shows one monthly price and no yearly plan, so the monthly price counts as the regular price^1,2.

Rackspace said it had no evidence the contents were viewed or misused. The article does not cover Rackspace Email¹⁵.
