A great name aside, IceWarp is an excellent browser-based email hosting option that combines cloud and on-premise technologies.
Its offerings, in particular, are worth highlighting -- as they include shared contacts and calendars, collaborative document editing, mailing list management, web meetings, audio and video calls, mobile apps and synchronization, and archiving. The dashboard, too, is an attractive interface for accessing emails, calendars, meetings, and files.
In regards to plans, IceWarp has a variety -- with the basic plan for startups and small businesses (with up to ten user accounts) priced at only $1.50 per user, monthly, with 200GB of email storage. Starting at $3.50/month per user, business plans are the next step up, but you will need to agree to 10 user accounts, at minimum.
If you decide you would rather go elsewhere within three months, IceWarp says you will not be charged.
