Make it an outlook plug-in and allow it to be used as an email managere as well.

What do you mean with "make it an outlook plugin"? Do you mean to integrate Wieldy into your Outlook? If so, why would it need to handle E-Mails then?

Actually Wieldy can Synchronize your Contacts and Calendar between Outlook and Wieldy. It could also synchronize your Todos, but i disabled this feature in the current releases. If i would also Sync E-Mails, Wieldy could theoretically replace Outlook.
