The Plumb Club

Member program · Member-brand social · LinkedIn, Instagram & Meta advertising · Board reporting

The Plumb Club is one of the jewelry industry's most established supplier organizations — a collective of leading manufacturers and brands who exhibit together each year in the Plumb Club Pavilion at JCK Las Vegas. Marketing an institution like this means serving the whole membership at once: many brands, one voice, and a board that expects to see results.

The Challenge

A trade organization markets on behalf of its members, not a single brand. The Plumb Club needed a consistent social presence and paid advertising that elevated the collective, promoted individual member brands — ALTR, Royal Chain, Richline and others — reached the right B2B audience, and reported back to a board, all while protecting the credibility of the organization.

What We Did

Luxury Brand Marketing ran the Club's member-brand social program and its paid advertising across LinkedIn, Instagram, and Meta, handling all 60 member brands around JCK Las Vegas and driving traffic to the Club's webinars and member pages. The LinkedIn B2B program alone delivered 1.26M targeted impressions at a $0.37 cost per click. Each year we prepared proposals and budgets for board approval and delivered board-level reporting with year-over-year comparisons.
