Zoho Mail
Forever free business email on your own domain.
Email
What you get
Ad-free email on your own domain for up to 5 users, with 5 GB of mail storage each.
How to get it
Click Sign up under Mail Free at zoho.com/mail.
What it requires
A domain you own; no card, per the pricing page.
The catch
No IMAP, POP or ActiveSync, so no Outlook or Apple Mail; the free plan is available only in select data centers, and from the 6th user everyone moves to a paid plan.
