I use Sequenzy for marketing emails, customer notifications, and announcements. Using AI to generate announcements and schedule and send them dramatically speeds up the process of writing these. It's very straightforward and easy to use. Having an MCP server with full response is great, and the technical support has been incredibly responsive, making workflows simple and addressing issues quickly. The setup was relatively straightforward.

I've been searching for an AI-native email campaign platform for a while and have tested all the major big-name apps. They were either ridiculously expensive at scale or lacked enough tools in the MCP for AI agents to use. Sequenzy is by far the best tool I found. It has a full-functioning free plan that's generous compared to other platforms. And it just simply works if you have a front-tier LLM driving the workflow. I use Claude Code with Opus 5 for my Sequenzy workflows, and the experience has been pretty flawless so far. By way of example, in the LLM capabilities using Sequenzy, other systems I've tried have about 30-60 tools in the MCP; Sequenzy currently has 163! It's like having a functioning comms team when you pair that with a strong LLM. Customer service is very good too; I casually suggested having a few other social media buttons in the email footer template, and 2 days later I got a DM saying they updated the platform and it's been added.

All round great email platform for SaaS businesses. Covers all the basis for a great price.
