Marketing Automation
Marketing automation is a three-way stalemate at the top. Salesforce, HubSpot, and Customer.io each surface across all engines and capture between 55% and 65% of AI discovery prompts, with Marketo and ActiveCampaign within five points. The evaluation stage offers no daylight — HubSpot, Salesforce, Customer.io, ActiveCampaign, Marketo, and Klaviyo all average a dead-even 47-50 wins-per-100 head-to-heads. The kingmakers are HubSpot and HubSpot Marketing Hub; the consensus picks are Salesforce and Customer.io; the absent giants are Sendpulse, Mailchimp, Sprinklr Marketing, Typeform, Omnisend, and Optimove, all of whom win head-to-heads but surface far less often in discovery. This is a contested category — no single brand captures AI attention, and no brand wins a meaningful edge when buyers ask AI to compare options.

Discovery stage
The shortlist
Across 212 buyer-style "Marketing Automation" queries
Six brands split discovery share within ten points of each other. Salesforce surfaces in 65% of buyer queries across all engines; HubSpot lands in 57%, Customer.io in 61%, Marketo in 55%, ActiveCampaign in 54%, and Klaviyo in 51%. Every one of these brands shows up across ChatGPT, Claude, Gemini, and Perplexity. Below the top tier, Pardot captures half of discovery prompts but rarely wins head-to-heads, while Hootsuite appears in just 17% of queries despite scoring well in evaluations.

Evaluation stage
Head-to-head
How often AI cites each brand across uniform category evaluation prompts · median 7/100
When buyers ask AI to compare marketing automation platforms, no brand wins a meaningful edge. HubSpot, HubSpot Marketing Hub, and Salesforce each win exactly half their head-to-head matchups; Customer.io, ActiveCampaign, Marketo, Salesforce Marketing Cloud, and Klaviyo all win 47-48 out of 100. The median brand in this category wins just 7 head-to-heads, so these eight are the only names AI engines consistently pick when buyers ask for a verdict. The stalemate spans three dozen comparison queries per brand — not a thin sample.
