What's new in this version:
Version 1.28 may include unspecified updates, enhancements, or bug fixes.
I like Zoho Mail, but the only barrier that kept me from making it my default mailbox was that it doesn't have real taskbar notifier. Howard Email Notifier is the only one that also notifies you of the total unread emails of all your combined email clients in Zoho. Besides Zoho, it supports, Outlook, Gmail, Yahoo, Facebook, Twitter and more.
