The Problem

Managing customer onboarding through email often results in poor engagement, with only 20% open rates leaving many new customers unreached. Manually sending welcome messages through WhatsApp is time-consuming and prone to human error, while traditional solutions require expensive WhatsApp Business API setups.

The Solution

WhatsScale integrates with Make.com and Google Sheets to automatically detect new contacts and send personalized WhatsApp welcome messages with 98% open rates. The system prevents duplicate messages by checking your CRM and works with your personal WhatsApp number—no Business API required.
