The Challenge

Annual summit stalled weeks before the date. Email fatigued the list; paid social CPL climbed.

The Solution

CTWA opt-in, segment broadcasts for speakers/agenda, abandoned registration recovery, and last-72-hour urgency sequences.

"WhatsApp did what email could not — create FOMO in real time during speaker reveals."

— Marketing Lead, Bangalore events agency
