The problem
Email was no longer doing the job
Chelsea Corporate had strong buy-side interest sitting in its CRM, but email response rates had softened. Prospects who had once engaged were harder to reactivate, follow-ups were easier to miss, and the team needed a channel that felt more immediate without compromising professionalism.
The brief was straightforward: reach interested buyers faster, make it easier to reply, and create a booking path that the team could trust operationally.
The build
Personalised video, quick replies, and controlled delivery
- We moved Chelsea Corporate onto the WhatsApp API so outreach could be sent through an approved, scalable business channel.
- We built campaign assets around personalised videos so each message felt direct, relevant, and worth opening.
- We added quick reply buttons that let recipients express interest and move straight into meeting-booking flows.
- We limited the number of messages sent each day and included obvious opt-out language so the campaign stayed compliant and readable.

Why it worked
The campaign matched the way buyers actually respond
The campaign matched channel to audience behaviour. Instead of relying on a crowded inbox, Chelsea Corporate spoke to prospects in WhatsApp with a format that combined a face-to-face feel, clear next actions, and low-friction responses. Personalised video handled attention. Quick replies handled action. The API layer handled scale and oversight.
