I was initially looking to outsource e-mail for my company's communications. We found Fusemail. Although, we now use our web-hosts mail servers, one of the neat features of the webmail interface of fuse is that you can add POP3, IMAP, Hotmail, Yahoo, etc.. all into the same interface, creating rules for that account for messages to go into one folder etc..
That is just the tip of the iceberg for me.
Here's a screenshot, showing some of the extra features:
As you can see, you get file storage, calender, notes, and more with the package. You also get an online Jabber client to connect with others on your fusemail package (mainly for business use). You can save "workspaces" to return to that exact same part next time you login.
There is also a notification client you can download to notify you of new email, in any mailbox on your account - whether that be your hotmail account or your fusemail account.
Only downside is no Outlook integration as of yet - but I believe that is coming. They have their own forums too.
Custom mail filters aswell, custom folders, IMAP/POP3 access as standard... the list goes on.
Anyone looking for a very
cost effective pay-for email account should really look no further. The features are second to none, and the account was set up automatically. It's all custom coded too, I believe.
If anyone wants a test account on my package to try it, just ask
