Most obstacles in marketing automation aren’t actually automation problems. 86.4% of marketing teams now use AI somewhere in their workflows. Yet, measuring ROI still tops the challenge list at 33%, according to HubSpot’s 2026 State of Marketing Report.

Ultimately, marketing automation issues are rarely tool problems. They are most often caused by unclear strategy, bad data, siloed tools, and weak team alignment. The automation platform executes those problems faster and at greater scale.

A tool with that much reach deserves a real strategy behind it.

So the fix? Always start with strategy. Before building any automation, the team should first define the following.

• The Owner: A named human should be accountable for each automation’s …read more
