When Sheraton Colombo wanted to create an unforgettable Mother’s Day brunch, they partnered with ECHT Social to make it a sold-out success. Our mission: transform low-converting call reservations into seamless WhatsApp bookings that convert.
The Challenge
Sheraton Colombo had struggled with phone call reservations, noticing high drop-offs and fewer confirmations. We needed a smarter, frictionless approach to turn interest into real bookings.
The ECHT Strategy
Channel Shift to WhatsApp We replaced calls with WhatsApp, making reservations instant and familiar for guests.
Creative Refresh We moved from a single static post to two new creatives: a dynamic reel showcasing the brunch atmosphere and a refreshed post highlighting buffet offerings.
Targeted A/B Testing We tested different interest-based audiences to identify the most responsive segments.
The Results
Bookings jumped from 11 to 75 in just three days, all via WhatsApp.
All guests were non-hotel residents, expanding Sheraton’s reach.
The simplified process significantly improved conversion rates.

Why It Worked
Ease and familiarity of WhatsApp reduced friction and built trust.
Dynamic visuals captured attention and drove immediate action.
Precise audience targeting ensured maximum return on spend.

The Impact
Sheraton Colombo’s brunch transformed from underbooked to fully booked overnight, proving that smart channel strategy and creative testing can unlock new growth.
