    It's clean, no ads, and free up to 500 MB. Looks so much better than Gmail.

    Excellent security, privacy, and censorship resistance, also has been in the game for a while now with good reliability (uptime, etc). Their client code is open source. Freemium business model.

    Zoho seem to have a more user friendly way to contact customer support for any problems. OMBx does not have any links in their email, nor can users do a 'search and find their support contact info. So I be moving to very Zoho soon.

    Startmail, after trial, costs about three times the price of OMBx and even tho "may be" somewhat more secure. OMB, Riseup, Tutanota, Zoho and other like email provides, paying 3 times the price is not cost effective for the fixed income users, or other economically challenged want-to-use-secure providers.
