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.

I use Sequenzy for email marketing on my SaaS, and I love the super easy setup. I got my campaign up in just 5 minutes, which was fantastic. I really appreciate the AI that writes campaigns for me, so I don't need to sit for hours manually crafting or AB testing the text. It's amazing how everything is hosted and connects to my domain in one click, saving me from spending 5 hours with AWS. The founder is also super helpful, when my saas got acquired he helped migrate everything the same day.
