Missive could use a combination of logic + Jev to create built in functionality to filter important emails from noise. Its extremely cheap to run bulk operations on and I don't even mind connecting my own API to enable this functionality

Also Jev could then be used for complex AI team routing and assignments: Give Missive an overview of your company, people's roles, etc (or provide some data source where this can be queried live). Send this roles/responsibilities/routing decision information to Jev, with a list of possible teams and users to assign in Missive. Let Jev assign them, falling back to some specified team on low confidence matches
