Automate WhatsApp Birthday Messages from Google Sheets
Last updated: 2026-03-09
The Problem
Managing birthdays for dozens or hundreds of contacts manually is time-consuming and error-prone. You either forget important birthdays or spend hours each week checking dates and sending individual messages. For businesses, missed birthdays mean lost opportunities to strengthen customer relationships.
The Solution
WhatsScale integrates with Make.com to automatically check your Google Sheets contact list every morning and send personalized WhatsApp birthday messages. The automation handles message scheduling and throttling, ensuring you never miss a birthday while staying within WhatsApp's sending limits.
