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.
ConvertKit
Kit (formerly ConvertKit) – The top recommendation specifically for creators and newsletter publishers focused on audience monetization.
Claude
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
ConvertKit
ConvertKit: Ideal for content creators and solo marketers prioritizing audience building and simple text-based emails.
Gemini
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
ConvertKit
Kit (formerly ConvertKit) — Best for independent creators selling newsletters, digital products, memberships, courses, or sponsorship inventory, because its subscriber-centric publishing and monetization orientation is more natural than a traditional business-marketing suite.
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
Where the models split.
Across the 3 categories ConvertKit and HubSpot 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 HubSpot ahead at least as often as not, with Gemini the most lopsided.
The race is tightest in Best Email Marketing Platforms (1 rank apart) and widest in Best Email Marketing Platforms 2026, where HubSpot leads by 7.
