How staffing managers waste 2 hours every morning

📱
WhatsApp one by one
Opening every contact manually, typing the same message over and over with a different name and time.
📞
Calling workers
30 seconds per call × 200 workers = 100 minutes. Half of them don't pick up on the first try.
😤
No confirmation tracking
You never know who confirmed and who didn't until workers start showing up — or not.

"We manage over 4,000 shift workers in Spain. Every morning we used to spend 2 hours notifying everyone via WhatsApp. Now we run a single send from SmsGateway24 — all 4,000 notifications go out in under 3 minutes, and confirmations flow back automatically.
