I use multiple email addresses for work, personal and various special projects. I would love the ability to set email reminders that will be sent to my work email address for work tasks and my personal email address for personal tasks. It would also be extremely useful for the task creation emails to come from multiple accounts.

The ability to register multiple email addresses for a single account would be extremely useful for me and others who like to keep their project management in one place even though their projects span multiple work spaces.
