How a Non-Technical Marketer Used n8n to build his emails | Michael Roberts (Boost My Email)


Listen Later

n8n is easy to lump in with every other "AI agent" tool getting hyped right now. It is not that. It is an open source workflow automation platform, the kind of tool you would compare to Zapier or Make, where you connect steps on a visual canvas and the data moves through them in order. No autonomy, no AI deciding what happens next.

Michael Roberts, a fractional lifecycle and email leader who runs his own practice, Boost My Email, used it to build something genuinely useful: a workflow that takes approved email copy from a Google Doc and builds the finished emails inside HubSpot automatically. Michael did this without a developer background.

In this episode, Michael explains what n8n actually is, why he chose it over writing his own scripts, the one rule that kept the build grounded (only automate tasks with no judgment involved), and runs a live demo of the workflow end-to-end. He also published a full technical write-up with the actual code for every step, linked below if you want to build something similar.
