Incredible as it sounds, Zapier is the elder statesman of AI marketing tools. The platform has morphed from a basic data transfer tool into a full-on automation engine. Thanks to near-universal adoption by SaaS apps and a robust set of native utilities, Zapier can automate just about any repetitive, data-driven marketing task. This includes distributing and routing sales leads, automatically emailing customers with upsells, or even utilizing the OpenAI API to create custom content on the fly. Zapier is priced by the "task," with certain premium apps and features adding to the cost. Most users can get away with spending $49/month or less.
