Platforms for newsletters, campaigns, and lifecycle email. Right now, Klaviyo is the brand AI assistants recommend most, with a Visibility Score of 50 and the #1 spot in 24% of answers. Head-to-head: Klaviyo vs Mailchimp →
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.
Klaviyo leads, but Claude's Mailchimp obsession distorts the whole race.
Mailchimp's Claude score of 73 is the most extreme per-model gap in the dataset, single-handedly inflating its overall rank while Gemini scores it at only 23. Klaviyo is the only brand with relatively consistent recognition across all three models, which makes its lead more durable than the raw scores suggest. Kit is quietly present in 54% of answers yet earns a first-pick rate of only 3%, meaning the models know it but rarely trust it enough to lead with it.
