Inbox Index vs Sentien

People-centric email

An average business user exchanges about 50,000 emails every year with over a thousand contacts. Email overload is a common problem that often results in email bankruptcy, that can badly damage relationships. Existing email tools and techniques are useless for managing correspondence with a large number of contacts.

Inbox Index has redesigned the email experience with a focus on relationships instead of messages. It’s about who - not what.

We help users to easily identify who’s important by intelligently organising contacts using data science.
