#1
ActiveCampaign
No change from the last closeconsensus 25
ActiveCampaign holds the consensus #1 at a score of 25, with Gemini placing it first outright.
ActiveCampaign — My strongest all-purpose pick for a serious SMB or mid-market team because its visual automations, behavioral segmentation, CRM-oriented workflows, and AI automation builder provide more lifecycle-marketing depth than a basic newsletter tool.
ChatGPT, this close
ActiveCampaign — Repeatedly called out as having 'the most granular automation builder' of any ESP, making it the best choice if complex behavior-driven sequences matter most.

#2
HubSpot
No change from the last closeconsensus 21
HubSpot ranks #2 on consensus with a score of 21, scoring best on ChatGPT (#1).
HubSpot Marketing Hub — Best if your sales, service, website, and CRM data already live in HubSpot, where its email personalization and automation can be genuinely powerful, but I would not buy it for email alone because advanced tiers get expensive fast.
ChatGPT, this close
HubSpot Marketing Hub — The default recommendation for B2B/sales-driven teams because email is natively tied to a full CRM and pipeline reporting, though it gets pricey at scale.
Claude, this close

#3
Klaviyo
No change from the last closeconsensus 18
Klaviyo ranks #3 on consensus with a score of 18, scoring best on ChatGPT (#1).
Klaviyo — The best choice for an established ecommerce brand, particularly on Shopify, because its customer and purchase data model, segmentation, predictive capabilities, and email/SMS lifecycle flows are exceptionally commerce-native.
ChatGPT, this close
Klaviyo — The consensus top pick for ecommerce, thanks to deep Shopify/BigCommerce data sync, fast segmentation, and unified email/SMS/push in one platform.

#4
Mailchimp
No change from the last closeconsensus 15
Mailchimp ranks #4 on consensus with a score of 15, scoring best on ChatGPT (#1).
The models disagree about it more than most: #1 on ChatGPT but #4 on Gemini, a spread of 3.
Mailchimp — Still a credible, easy starting platform with a familiar editor and broad integrations, but it ranks last here because comparable alternatives usually offer better automation depth or better economics as your list and needs grow.
ChatGPT, this close
Mailchimp — Still the most recognized name with the largest integration ecosystem (800+), a solid all-rounder for small businesses despite a scaled-back free tier.

The models disagree about it more than most: #1 on ChatGPT but #6 on Gemini, a spread of 5.
It slipped 1 position at the latest close.
Brevo — The platform I would choose for value-conscious businesses with a large or lightly mailed list, since it combines email, transactional sending, basic CRM, and multichannel automation while pricing primarily by send volume rather than stored contacts.
ChatGPT, this close
Brevo — Frequently the pick for EU-based teams and budget-conscious senders, offering email, SMS, and CRM-lite features with EU-hosted infrastructure for compliance.
Claude, this close

MailerLite — My top recommendation for a small business that chiefly needs attractive newsletters, forms, landing pages, and straightforward automation without the complexity or price of a full marketing suite.
ChatGPT, this close
MailerLite — Consistently praised as the best low-cost, easy-to-learn option for newsletter creators and small businesses just starting with automation.

No change from the last closeconsensus 8
Omnisend ranks #8 on consensus with a score of 8, scoring best on ChatGPT (#1).
The models disagree about it more than most: #1 on ChatGPT but #8 on Gemini, a spread of 7.
Omnisend — The best Klaviyo alternative for small-to-midsize ecommerce teams that want a simpler, more cost-conscious email, SMS, and web-push stack with strong ready-made store automations and support.
ChatGPT, this close
Omnisend — The go-to alternative to Klaviyo for ecommerce brands wanting deep Shopify integration at a somewhat gentler price point.

ChatGPT, this close
GetResponse — Valued for its especially robust feature set (webinars, landing pages, automation) at SMB-friendly pricing.

How are these rankings measured?

We ask each model the same buying questions on every run (0 queries this period), record the full answers, and score each named brand 0-100 by how early and how consistently it appears. Every question runs through the official model APIs, with web search on, not through the consumer chat apps, so nothing is personalized to a user. Each model is scored independently; the consensus blends all 4.

Do the AI models agree with each other?

At the top, yes. Every model crowns the same #1 at the latest close. Further down the board they diverge, which is why each brand carries a spread figure: the gap between its best and worst model rank.
