Two tools, two different jobs. Klaviyo is a full marketing platform across email, SMS, and more. CartGhost is a focused WhatsApp cart recovery app for Shopify. Side-by-side facts, no editorializing — pick what fits your stack.
A purpose-built Shopify app that does one job: reach abandoned carts on WhatsApp with AI-driven, conversational replies.
A broad ecommerce marketing suite covering email, SMS, WhatsApp, push, segmentation, AI assistants, and 350+ integrations.
The high-level feature differences in one table.
| Capability | CartGhost | Klaviyo |
|---|---|---|
| Primary channel | Email (also SMS, WhatsApp, push) | |
| Tool type | Single-job Shopify app | Multi-channel marketing platform |
| Pricing model | Flat: Free or $29/mo | Scales by active profiles[3] |
| Free plan | ✓ Unlimited cart recoveries, 1 template | ✓ Up to 250 profiles, 500 emails/mo[2] |
| AI features | Claude-powered conversational replies, AI message generation | Marketing Agent, Customer Agent, Segment AI, predictive analytics[4] |
| Setup time | ~5 minutes | Hours to days (multi-channel setup) |
| Best fit | Shopify stores in WhatsApp-heavy markets that want focused cart recovery | Stores that need full email + multi-channel marketing under one roof |
| Channel | CartGhost | Klaviyo |
|---|---|---|
| ✓ Native, AI-driven | ✓ Available since 2024[2] | |
| ✗ Not planned | ✓ Core platform | |
| SMS | On roadmap | ✓ Credits-based |
| Mobile push | ✗ | ✓ |
| RCS | ✗ | ✓[4] |
The job most Shopify merchants buy these tools for in the first place.
| Feature | CartGhost | Klaviyo |
|---|---|---|
| Trigger | Shopify cart-abandonment events (real-time) | Shopify "Checkout Started" + "Added to Cart" events |
| Cart state at send | Pulled live from Shopify Cart API at message send time | Captured at trigger time |
| Conversational AI replies | ✓ Claude answers product / shipping / sizing questions in-thread | Templated replies via Marketing Agent |
| A/B testing | ✓ Pro plan | ✓ All paid plans |
| Discount rules by cart value | ✓ Built in | ✓ Via flow logic |
| Open / read rate (channel-level) | 90–98% WhatsApp delivered-read[5] | 50.5% email open rate (Apple MPP-inflated since 2021)[1] |
| Recovery rate (case studies) | 15–25% on WhatsApp (D2C cohort)[6] | 3.33% average on Klaviyo email flows[1] |
Recovery rates above are vendor-reported and channel-level — treat as case studies, not guarantees. The structural difference (WhatsApp's read signal is stronger than email's pixel-based open) is the durable observation.
| Capability | CartGhost | Klaviyo |
|---|---|---|
| AI message generation | ✓ Brand-matched copy | ✓ Marketing Agent[4] |
| Conversational AI in-channel | ✓ Claude handles WhatsApp replies natively | Partial — Customer Agent for support |
| Predictive analytics (CLV, churn) | ✗ | ✓ |
| AI segmentation | ✗ | ✓ Segment AI[4] |
| AI subject line generation | N/A (no email) | ✓ |
CartGhost charges a flat fee. Klaviyo scales with your active profile count (changed February 2025).[7]
| Plan | Price | Includes |
|---|---|---|
| Free | $0 forever | Unlimited cart recoveries, 1 pre-built template, basic dashboard, "Sent via CartGhost" footer |
| Pro | $29/mo flat | Unlimited custom templates, AI auto-replies, A/B testing, full funnel analytics, no branding |
WhatsApp messaging fees are billed by Meta directly to your WhatsApp Business account. CartGhost does not mark them up.

| 100,001+ | $1,440 – $2,300+ |

Most stores running both: Klaviyo for email + multi-channel marketing, CartGhost for WhatsApp cart recovery.
Many Shopify merchants run both — Klaviyo handling email and multi-channel campaigns, CartGhost handling WhatsApp cart recovery. The two tools don't currently integrate directly; the recommended setup is to pause Klaviyo's abandoned cart email flow when CartGhost is installed, or stagger the timing so WhatsApp fires first and email is the fallback.
No. CartGhost is a focused single-job tool for WhatsApp cart recovery. Klaviyo is a multi-channel marketing platform. Most CartGhost users run it alongside Klaviyo or another email tool.
Yes. The recommended setup is to keep Klaviyo running email (newsletters, winback, post-purchase) and let CartGhost handle WhatsApp cart recovery. To avoid double-messaging, most merchants pause Klaviyo's abandoned cart email flow when CartGhost is installed.
Klaviyo scales by active profile count: $20/mo at 500 profiles, $1,380/mo at 100,000 profiles for email plans (SMS and WhatsApp on top, credit-based). CartGhost is flat: Free or $29/mo regardless of list size. WhatsApp messaging fees are billed by Meta directly in either case.
SMS is on the public roadmap. Email is not planned — CartGhost is intentionally focused on WhatsApp.
Best in markets with high WhatsApp adoption (LATAM, EU, MENA, India, Southeast Asia, Brazil). In US/Canada, where consumer WhatsApp use is lower, recovery rates may be below typical benchmarks. We'd rather you know before installing.
Free forever. Unlimited cart recoveries on the free plan. Runs alongside your existing Klaviyo setup.
