The Challenge

Sales and support teams were managing contacts across spreadsheets, email inboxes, and WhatsApp — with no unified history, no accountability for follow-ups, and no visibility into which leads were going cold. Email deliverability issues were discovered only after damage was already done to sender reputation.

The Solution

ContactHub consolidates all contact interactions, channels, and workflows into one platform. The React Native mobile client gives field teams full CRM access on iOS and Android. Automated inquiry routing and SMTP monitoring transform reactive teams into proactive ones.
