- •The AI writing tool is helpful for overcoming blank-page syndrome but requires heavy editing to sound human.
Penny's Verdict
ConvertKit (which is rebranding to Kit) remains the best 'boring' tool for serious business owners. I call it 'boring' as a compliment—it works exactly how it should without the bloated features of Mailchimp or the fragility of cheaper alternatives. Their AI integration is sensible; they aren't trying to replace the creator, they're just trying to remove the friction of formatting and brainstorming. However, be careful with the costs. ConvertKit is a premium tool. If you're just starting out and don't have a product to sell yet, the £25/month price tag for the 'Creator' tier (needed for automation) can be a drain. Use it when you have a clear path to ROI. If you're an e-commerce brand with hundreds of SKUs, this isn't for you—go to Klaviyo. If you are the brand, this is your home.
