How B2B Brands Waste Ad Spend on Lookalike Audiences Built from Bad Seed Data

Episode notes

Lucas and Luna dig into a marketing-ops blind spot that costs B2B brands millions: building Facebook and LinkedIn lookalike audiences from seed lists polluted with bad email addresses, old contacts, and typos. They walk through a concrete example - a mid-market SaaS company that uploaded 50,000 CRM contacts to create a lookalike, only to discover 38% of those seeds were undeliverable or irrelevant. The hosts break down how garbage-in-garbage-out inflates CPMs, wastes ad budgets, and skews attribution, then offer a specific fix: running seed data through an email verification API and CRM deduplication before it ever touches the ad platform. Tune in for a tactical, numbers-driven episode that connects data hygiene directly to ROAS. #B2BMarketing #MarketingOperations #Martech #LookalikeAudiences #AdSpendWaste #DataHygiene #EmailVerification #CRMDeduplication #FacebookAds #LinkedInAds #CustomerAcquisitionCost #ROAS #SeedData #FexingoBusiness #BusinessPodcast #MarketingAutomation #DigitalAdvertising #B2BSaaS Keep every episode free: buymeacoffee.com/fexingo
