We limit the number of plans to agencies per expertise and per geographic area. You can see/count it for yourself on our public pages:
Official member agencies in Belgium: https://www.sortlist.be/fr/marketing/belgique-be
Official member agencies in France: https://www.sortlist.fr/marketing/france-fr
Official member agencies are promoted on these pages and you can distinguish them by an 'official sortlist member' badge (see below picture).
