What the models actually said.
The ranking is the answer; these are the words behind it. Every quote is from a recorded model answer — follow the category to read it whole.
Klaviyo
My genuine default recommendation is Klaviyo for ecommerce, HubSpot for B2B companies already—or deliberately—building around a CRM, and ActiveCampaign for a capable small-to-mid-sized business that wants strong automation without adopting the full HubSpot stack.

Sender
Sender — A solid budget-friendly option for startups and small businesses that want a generous free plan and simple automation.
Perplexity
Where the models split.
Across the 1 category Klaviyo and Sender both appear in, the models never break ranks: in each one, the same brand leads on ChatGPT, Claude, Gemini, and Perplexity alike.
No model runs against the grain here: each of the four ranks Klaviyo ahead at least as often as not, with Claude the most lopsided.
