### 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.
