Marketing automation
Marketing automation is software that runs repeatable marketing work from rules set once — email sequences, lead scoring, campaign triggers — instead of someone sending each step by hand.
HubSpot, Customer.io, and the email product inside your CRM are this. A person enters a segment; the system waits, sends, branches on a click, and updates a score. The value is cadence you can trust, not a clever model.
It overlaps workflow automation at the edges. Marketing automation lives in a marketing tool and speaks campaigns. Workflow automation lives across tools — CRM, Slack, a sheet — and is what we build in n8n when the campaign product cannot see the rest of the stack.
The failure is a sequence nobody owns. Leads get the wrong email, the score is a guess, and unsubscribes pile up. We wire the triggers and the handoff; we do not replace a marketer's judgement about what the message should say.
