If you're a small business owner drowning in manual email campaigns, you already know the problem: too many contacts, not enough time, and zero budget for a dedicated marketing team. AI email marketing tools have changed the game — automating sends, personalizing at scale, and writing subject lines that actually get opened. The question is which one is right for your business.
Best overall: Mailchimp — easiest to start with, a free plan for up to 500 contacts, and AI-assisted content creation that works without a learning curve. For growing e-commerce brands, Klaviyo pulls ahead fast.
