Klaviyo
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.

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.

Perplexity
Where the models split.
Across the 5 categories Klaviyo 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 Klaviyo ahead at least as often as not, with Gemini the most lopsided.
The race is tightest in Best Email Marketing Platforms in 2026 (4 ranks apart) and widest in Email Marketing Platforms, where Klaviyo leads by 8.
