Case Study: World's Largest Brand Consultancy achieves 76% RSVP rate and 39 qualified leads in 22 days with Callbox

World-class Branding Consultancy Gets Marketing Boost with Callbox

Largest Brand Consultancy, the world’s largest brand consultancy with 33 offices in 27 countries, needed to drive fast, high‑quality registrations for free seminar workshops in Singapore and Thailand. They engaged Callbox to combine targeted email outreach and outbound telemarketing to identify target contacts and qualify prospects against the consultancy’s criteria.

Callbox executed a two‑wave campaign—email invitations to C‑level contacts from the top 200 local companies, followed by outbound telemarketing to qualify respondents and forward RSVPs, with weekly reporting to the client. In just 22 days Callbox delivered 39 qualified leads and 30 confirmed RSVPs (a 76% RSVP rate), and the client added another Callbox agent to scale the effort.
