A combination of high interest rates and an uncertain economy made companies extremely skittish, and that caused them to pull back on their marketing spend.   There’s some recent signs that advertising spending is picking up in 2024, but it’s still too early to know how it will shake out.   But what about newsletter advertising? It’s seen some strong growth in recent years and brands have reported higher than average ROI due to the strong engagement that’s seen in the inbox. Has it suffered from the same macro economic forces that battered the larger ad industry?   To answer that question, I turned to Ryan Sager, the co-founder of Who Sponsors Stuff, a data platform that tracks sponsorships across hundreds of newsletters. Ryan dove deep into his own data to determine which sectors are investing big in newsletter ads and whether they’ve seen any slowdown in growth.
