Common Small Business Concerns
"I don't have time": Email automation handles repetitive tasks. Initial setup pays off indefinitely.
"I don't have a big list": Small, engaged lists outperform large, unengaged ones. Start where you are.
"I'm not a writer": Templates and simple formats work great. Authenticity beats polish.
"I don't know the technology": Modern platforms are designed for non-technical users. Learning curve is minimal.
