Top pick for most shops
Kit
Best for: shops that build an audience around makers' work and sell digital files alongside physical goods.
Kit's free plan includes unlimited landing pages, forms and email broadcasts, plus tagging and segmentation. Tags matter for a maker: a buyer of one pattern can be tagged differently from a buyer of finished goods, so the next message reflects what they bought. Kit also lets you sell digital products and subscriptions on the free plan, which suits pattern sellers and printable shops.
Where it falls short: visual automations and email sequences start on the Creator plan, so post-purchase flows and multi-step launch sequences cost $33 a month billed yearly. Kit is not an ecommerce platform, so it will not replace a store's inventory or cart logic.
Price: free up to 10,000 subscribers. Creator is $33 a month billed yearly, and Pro is $66 a month billed yearly. A 14-day trial is available on paid plans without a credit card. Kit's pricing page lists the current details.
