Customer.io: AI Visibility Report
When buyers ask ChatGPT, Claude, and Gemini about marketing automation, Customer.io ranks #9 of 15, a Visibility Score of 12 in Marketing Automation .
These rankings are measured from what the three models know from training, not a live web search. The live-web grounded surface is rolling out across the index. Methodology.
One category, one race, and Customer.io is losing it.
Where it wins. A 22% mention rate in Marketing Automation keeps Customer.io in the conversation, and budget-focused queries are its clearest point of entry where AI models reliably surface it as a HubSpot alternative.
Where it loses. Rank 9 of 15 with a 1.4% first-pick rate means buyers hear the name but move on, and the complete absence from Best Overall and Enterprise Pick prompts locks it out of the queries that drive high-value deals.
AI-generated analysis of the September 2026 measurements.
Customer.io claims Marketing Automation and the models back it: #7 of 15 there.
