Mailplane 3 vs Boxy

The tabbed interface included in Mailplane 3 lets users work with as many Gmail accounts simultaneously as they want.

Mailplane 3 combines Google Calendar and Gmail within a single app.

Mailplane 3 looks just like Gmail's web UI and even imports Gmail shortcuts. If Gmail shortcuts aren't ideal for the user, those of Mac can be used instead.

Functionality and features can be extended by using plugins.

Boxy is simply a wrapper around Google Inbox. People who are used to Inbox's web interface will feel right at home with Boxy.

If an email contains pictures, flight information, reservation at a restaurant, attachments, links, dates, phone numbers and other information that the application recognizes, it will surface that information in its main view. These items can be viewed and interacted with without having to open the message itself. It allows finding and taking action on the important email information quickly.

Inbox tries automatically bundling similar messages together. For example, Inbox will create bundles for travel information, receipts, promotions as well as group messages temporally. It enables also managing these bundles of messages together - they can all be swiped away together.
