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.
ActiveCampaign
ActiveCampaign — My default pick for a growing service, B2B, SaaS, or SMB business because it combines notably deep behavior-based automation with email marketing and CRM capabilities without requiring a full enterprise marketing suite.
ChatGPT
MailerLite
MailerLite — A very strong practical choice for a small team that wants an approachable editor, simple automations, and good value rather than an enormous, complicated marketing stack.
ChatGPT
ActiveCampaign
ActiveCampaign — My strongest general recommendation for a growing SMB because it pairs genuinely deep visual automation, segmentation, CRM/ecommerce integrations, and expanding AI-assisted automation without forcing you into a heavyweight enterprise suite.
ChatGPT
MailerLite
MailerLite — A very good choice for small businesses that prioritize an uncomplicated interface, attractive campaigns, landing pages, and sensible email automation over an enormous feature set; I would shortlist it before Mailchimp for many straightforward programs.
ChatGPT
ActiveCampaign
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
MailerLite
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
ActiveCampaign
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
MailerLite
MailerLite — The best low-complexity choice for a small business, nonprofit, or service company that mainly needs attractive newsletters, landing pages, forms, and sensible automations without an enterprise-style learning curve.
ChatGPT
ActiveCampaign
ActiveCampaign — Another strong option for inbox placement, with EmailToolTester reporting a 94.2% deliverability rate and a top ranking in its tests.
Perplexity
MailerLite
MailerLite — A strong all-around email platform, and EmailToolTester’s deliverability tests gave it a 94.41% average and a “best of 5” award.
Perplexity
Where the models split.
Across the 5 categories ActiveCampaign and MailerLite 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 ActiveCampaign ahead at least as often as not, with Gemini the most lopsided.
The race is tightest in Email Deliverability & Sending Tools (1 rank apart) and widest in Best Email Marketing Platforms, where ActiveCampaign leads by 11.
