Klaviyo: Email & SMS, our full review (reviews, installation, pricing)

What is Klaviyo: Email & SMS?

Klaviyo (previously covered in this project) has expanded its AI positioning further, now centered on Klaviyo AI Agents managing flows and a "Composer" tool that analyzes the store and drafts ready-to-use campaigns. It shows a 4.7/5 rating on 2,945 reviews. It's developed by Klaviyo.

How does the app work on a Shopify store?

The B2C CRM syncs Shopify data in real time to reflect every event, consolidating data from over 350 integrations. Composer analyzes the store and builds ready-made campaigns, AI helps create segments and flow triggers from that data, and a Customer Hub/Agent turns customer service interactions into purchases. Conversions can be driven through email, SMS, WhatsApp, push and personalized pop-ups. It covers 10 languages, including French, German, Spanish and Italian, and connects to Gorgias, Recharge, Meta Advertising, TikTok Advertising and Typeform.

Why choose Klaviyo over another email marketing app?

Composer, which analyzes the store directly and drafts campaigns automatically, is a more proactive AI feature than most competitors' assisted-writing tools, worth testing directly to judge output quality against a store's actual catalog and voice. The Customer Hub/Agent turning support conversations into sales is a distinctive bridge between customer service and marketing not offered elsewhere in this project's email category. Pricing is tiered separately by channel (SMS starting at $15/month, email starting at $20/month for 251-500 contacts), a structure worth mapping out carefully if a merchant plans to use both channels together, since the true combined cost isn't obvious from either tier alone.

What are the 3 main features of the app?

1. Composer, an AI tool that analyzes the store and drafts ready-to-use campaigns.
2. Customer Hub/Agent, turning support interactions into purchases.
3. Real-time Shopify data sync, consolidated with 350+ integrations.
