What Is Klaviyo and What are Its Core Features?

Klaviyo is an all-in-one email marketing and SMS platform built for online stores and direct-to-consumer brands. It ties customer events and purchase data to messaging, enabling you to run lifecycle campaigns, reduce churn, and lift average order value through personalization and automation. The platform appeals to brands that need data-driven targeting, predictable flows, and tight integrations with commerce platforms to scale their retention programs.

Segmentation: Slice Customers by Behavior and Value

Klaviyo lets you build segments from purchase history, browsing, email engagement, and custom events so you target the right group at the right time.

Ground AI helps brands do precisely that with an eCommerce personalization platform built to drive revenue. Brands using Ground grow, on average, 20 percent more a year. That is $200K in extra revenue if you are making $1M today.

Drop a single script into your theme or tag manager, authenticate once, and let Ground map products, customers, and events to our models. We sync with your CRM and analytics, use event-based triggers, and begin personalizing on-site, in email, and over SMS almost immediately. The setup takes minutes, and the platform scales with your catalog and API traffic, so you do not need costly engineering time.

Why Ground AI Outperforms Basic Automation and How Klaviyo vs Iterable Compare

Klaviyo and Iterable are strong email automation tools that offer segmentation, flows, templates, A/B testing, and SMS. They handle list management, deliverability, suppression lists, and lifecycle marketing well. Ground layers predictive models on top of those capabilities to add dynamic product recommendations, predictive lifetime value scoring, behavior-based triggers, and multichannel orchestration.

Instead of just sending an abandoned cart flow or a promotional blast, you get personalized cross-selling, replenishment timing, and subscription prompts tied to revenue attribution and real-time analytics. Ground integrates with their APIs and enhances segmentation, reporting, and campaign builder results.

How Ground Produces a 20 Percent Revenue Lift

We combine acquisition optimization, cart salvage, and repeat purchase activation. Machine learning surfaces the best following product, best channel, and best discount for each customer. The system predicts churn and replenishment windows, then triggers lifecycle messaging and subscription offers.

We also improve deliverability signals by cleaning lists and switching to SMS fallbacks when email bounces, which recovers lost conversions and raises revenue per recipient. Imagine turning marginal buyers into loyal customers and small lifts into a six-figure revenue delta.

Acquire More First-Time Customers Automatically

Ground builds high-intent lookalike audiences from your best buyers and feeds them to ad platforms while simultaneously personalizing on-site creative and pop-ups to boost email capture. Event-based segmentation enables you to trigger precise landing content for ad traffic, while CRM sync keeps your audience lists tight. This boosts cost per acquisition and improves downstream metrics like conversion rate and lifetime value.

Convert Bounced Sales and Abandoned Carts into Orders

When email bounces or carts are abandoned, Ground routes the recovery to the optimal channel. We detect delivery failure, switch to SMS or push, and send tailored offers that match user behavior. Our flows include transactional clarity, A/B tested copy, and dynamic content, so every message aims to recover revenue with clean reporting and attribution.

Increase Repeat Purchase Revenue with Cross-Selling Replenishment and Subscriptions

We analyze purchase intervals and product affinity to time replenishment messages and recommend complementary products that convert. Subscription nudges adapt to user signals, and lifetime value predicts which customers will accept recurring plans. That raises average order value and repeat rate while keeping your templates and campaign calendar intact.
