ChatGPT answered 3× this snapshot

“Best” depends a lot on what you’re trying to do, but here’s a grounded way to think about it so you don’t end up overpaying or picking something bloated. If you want a quick answer: For most people: Mailchimp or Brevo (formerly Sendinblue) For creators: ConvertKit For ecommerce: Klaviyo For advanced automation: ActiveCampaign Here’s how they actually differ in practice: Mailchimp Good all-arounder, easy to use,…

Named across its answers: 1. Mailchimp2. ActiveCampaign3. Brevo4. Kit5. Klaviyo

Verbatim excerpt from one collected ChatGPT answer; formatting flattened, words untouched.

Mailchimp dominates completely, appearing in all 9 answers with a first-mention rate of 6 of 9 and an average position of 2.1, while Klaviyo matches its presence but never leads. HubSpot's absence from ChatGPT yet full presence in Claude shows model-specific bias that marketers relying on a single AI for vendor research will miss.
