About Klaviyo
What is Klaviyo (2026 update)
Klaviyo is an email and SMS marketing automation platform built for ecommerce brands to send personalized campaigns, automated flows, and customer messages based on shopper behavior. In 2026 it has pushed further into agentic AI, moving from a tool that helps you build campaigns to one that can draft and run entire marketing programs and customer service conversations with limited human input.
What is new in 2026
The headline addition is Composer, an agentic feature that generates, optimizes, and recommends full marketing campaigns and flows from a single prompt. As of an August 2026 update, Composer can draft flows, segments, and push notifications together from one instruction instead of requiring you to build each piece separately. Klaviyo also expanded Customer Agent, its AI support agent, so it now works across email and WhatsApp in addition to chat and SMS, with ready-made retail tasks like order tracking, returns, exchanges, subscription changes, and loyalty lookups built in. A new Agent Guidance feature lets you define exactly how Customer Agent communicates, its tone, its decision rules, and when it should escalate to a human. On the personalization side, next-best-product recommendations now run across email, mobile push, and WhatsApp, and personalized send time uses reinforcement learning to time each message to when an individual subscriber is statistically most likely to engage. Klaviyo describes this as part of a wave of more than 75 new features released in 2026 across marketing, service, and analytics.

Pricing in 2026
Klaviyo prices by number of active profiles rather than total contacts, a model it moved to in 2025 and kept through 2026. The free plan covers up to 250 active profiles, and paid tiers scale up from there with separate pricing for email-only versus email-plus-mobile bundles.
| Plan | Price | What you get |
|---|---|---|
| Free | Free | Up to 250 active profiles, 500 emails/month, $5 mobile and Composer credit/month, email support for first 60 days |
| Email (entry tier) | From about $20/month for 500 profiles | Full email automation, segmentation, and reporting beyond the free tier |
| Email + Mobile (entry tier) | Roughly $15/month more than the Email plan at the same tier | Adds SMS and mobile push messaging credits on top of email |
| Enterprise (250,000+ profiles) | Custom, manual billing | Custom contract, dedicated support, higher-volume infrastructure |
Costs increase in steps as your active profile count grows, and Klaviyo’s own pricing page recommends requesting a demo for exact current per-tier numbers since add-ons like Composer, Customer Agent, and Advanced KDP change the total. Check the official pricing page for the exact rate at your contact volume.
Who should use it
Klaviyo fits ecommerce brands, especially on Shopify, that want deep behavioral segmentation and automated flows tied directly to purchase and browsing data. It suits teams ready to hand off first-draft campaign building to an AI agent like Composer, and brands that want a single platform for both marketing messages and AI-driven customer service. It is less suited to non-ecommerce businesses or teams on a tight budget, since costs rise quickly as your subscriber list grows past the free tier.
Limitations and alternatives
Klaviyo’s active-profile pricing model can get expensive as a list grows, and newer AI features like Composer and Customer Agent add further cost through credits and add-ons rather than being fully included at every tier. The free plan’s email support only lasts 60 days, which can leave new users without help once trial support ends. For alternatives, Omnisend offers similar ecommerce-focused email and SMS automation at generally lower price points. Mailchimp remains a broader, less ecommerce-specific option with a larger free tier for general marketing use. Attentive focuses specifically on SMS marketing for brands that want to prioritize text over email.
