Building the right marketing stack in 2026 isn’t about collecting the most tools, it’s about choosing the ones that work together. The average small business uses 8 to 12 different platforms for CRM, email, scheduling, analytics, and inventory. That’s 8 different logins, 8 different data silos, and 8 different monthly bills.
