Klaviyo: User reviews, pricing & features

Klaviyo is the e-commerce anchor of our catalog: an email platform built around online-store data, spanning e-commerce email, email marketing, and marketing automation. We confirmed klaviyo.com serves the platform directly in August 2026 (the site geo-served a localized variant on the same domain).

Its pricing page offered an exact match for our normalization volume: the Email plan costs $30/month at 1,000 profiles with 10,000 sends, billed monthly only. A free plan covers up to 250 profiles and 500 emails per month. Pricing checked 19 August 2026. Klaviyo's curve is the steepest in our marketing capture: at 1,000 profiles its $30/month sits mid-pack, but at 50,000 profiles the same plan costs $720/month — the most expensive functional tier we recorded at that volume (multi-volume capture, 21 August 2026).

Scored 0–100 from public evidence: an official MCP server weighs most (40, +5 when hosted), then official agent skills, AI assistant apps, AI-friendly docs and built-in AI features. "Not found" means we couldn't locate it on Klaviyo's public pages or the official MCP registry, not that it can't exist. This is context, never part of the Deliverability Score.
