A sidebar add-in that auto-detects contacts in open emails, logs conversations to Salesforce, and surfaces deal stages and open tasks without leaving Outlook.

The Challenge

SalesTech's 50-person sales team was spending 2+ hours per day switching between Outlook and Salesforce to log emails, update contact records, and check deal stages. Reps often skipped logging altogether, leaving CRM data stale and making pipeline forecasting unreliable.

Our Solution

We built an Outlook add-in that activates on email open and reads the sender/recipient addresses via the Office.js API. The add-in queries Salesforce in real time to match contacts and deals, displays a rich sidebar with the contact's pipeline stage and open tasks, and provides a one-click 'Log to CRM' button that writes the email thread to Salesforce — all without leaving Outlook. OAuth 2.0 handles authentication with zero IT-managed credentials.

Key Results

  • Saved an average of 2 hours per sales rep per day
  • CRM email logging rate increased from 40% to 97%
  • Pipeline forecast accuracy improved by 35% in the first quarter
  • Rolled out to 50 users in under a week with zero downtime

Our reps actually log their emails now. The add-in made it easier to update Salesforce than to skip it — that's the bar we needed to clear.
