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.
HubSpot
HubSpot Marketing Hub — Best for B2B teams already using—or genuinely prepared to adopt—HubSpot CRM, since email, attribution, lead management, sales context, and web activity live in one system.
ChatGPT
Mailchimp
Mailchimp — Still a credible, easy-to-find general-purpose option with a large integration ecosystem and polished campaign tools, but I would usually choose ActiveCampaign, Brevo, or MailerLite first because they tend to offer better automation depth or value for the money.
ChatGPT
HubSpot
HubSpot Marketing Hub — Choose it when email marketing must live inside a broader CRM, sales, lead-management, content, and reporting system; it is powerful but usually overkill and comparatively expensive for email alone.
ChatGPT
Mailchimp
Mailchimp — Still a credible default for straightforward campaigns and broad third-party integrations, but I would choose it mainly when its specific integrations or familiar workflow matter—not because it is automatically the best value or deepest automation option.
ChatGPT
HubSpot
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.
ChatGPT
Mailchimp
Mailchimp — Still a credible, easy starting point for basic email marketing thanks to its broad integrations, templates, forms, automation, and reporting, but I would usually choose one of the more specialized options above for a serious growth program.
ChatGPT
HubSpot
HubSpot Marketing Hub — The right answer when email must operate as part of a broader CRM, sales, content, and attribution system, although it is usually overkill and expensive if you only need an email platform.
ChatGPT
Mailchimp
Mailchimp — Still a reasonable easy-to-start generalist with a polished campaign builder and broad integrations, but I would only choose it when its familiar interface or a specific integration outweighs better automation/value elsewhere.
ChatGPT
Where the models split.
Across the 4 categories HubSpot and Mailchimp both appear in, the models never break ranks: in each one, the same brand leads on ChatGPT, Claude, Gemini, and Perplexity alike.
Model by model, Gemini is HubSpot's strongest backer, placing it ahead in 3 of the 4; Perplexity leans the other way, favoring Mailchimp in 3.
The race is tightest in Best Email Marketing Platforms 2026 (1 rank apart) and widest in Best Email Marketing Platforms, where Mailchimp leads by 7.
