What is Kit?
Kit, formerly ConvertKit, is an email marketing platform built specifically for creators — writers, YouTubers, podcasters, course sellers, and other independent professionals who make a living from their audience. Where general email tools treat every user the same, Kit is designed around the creator's journey of building, nurturing, and monetising a following. Its features, philosophy, and even pricing reflect a deep focus on helping creators turn an email list into a sustainable business, which has earned it a devoted following in the creator economy.
The platform centres on growing and engaging an audience through email. It offers customisable signup forms and landing pages to capture subscribers, powerful tagging and segmentation so you can treat different parts of your audience appropriately, and visual automations that send the right emails based on what subscribers do. Kit also includes commerce features that let creators sell digital products and subscriptions directly, plus tools for recommending and being recommended by other creators, all aimed at helping independent creators both reach more people and earn from their work without stitching together many separate tools.
Kit is used by creators of all kinds who see their email list as the foundation of their business and want a platform tailored to that reality. The value is creator-focused capability: powerful automation and audience tools combined with built-in monetisation, all designed around how creators actually work. Because email remains one of the most reliable and direct ways to reach an audience — unmediated by social algorithms — having a platform purpose-built to grow and monetise that audience is genuinely valuable. For any creator who wants to build a real relationship with their followers and turn it into income, Kit offers a thoughtfully designed, creator-first email marketing solution.
What is Klaviyo?
Klaviyo is a marketing and customer-data platform built for consumer brands — especially ecommerce — that unifies all your customer data and uses it to power highly personalized, automated marketing across email, SMS and more. Trusted by 205,000+ brands in 100 countries, it's become the go-to for online stores that want their marketing driven by real customer behavior.
What Klaviyo is
Klaviyo combines a customer data platform (CDP), marketing automation, analytics and, increasingly, AI agents and customer service into one system. It pulls every signal about your customers — purchases, browsing, engagement — into unified profiles, then uses that data to send the right message on the right channel automatically, whether that's an abandoned-cart email, a win-back SMS or a personalized recommendation.
Who it's for
Klaviyo serves relationship-driven B2C brands: ecommerce and retail businesses above all, but also gyms and wellness centers, restaurants, and enterprises. It's for companies whose growth depends on turning customer data into repeat purchases and loyalty — and who've outgrown a basic email tool that doesn't know what their customers actually do.
What it offers
- Customer Data Platform with unified profiles (7.3bn profiles managed)
- Omnichannel messaging: email, SMS, RCS, WhatsApp, push and social
- Real-time personalization and segmentation
- Composer AI agent that builds on-brand campaigns from prompts
- Customer Agent that resolves ~65% of inquiries autonomously
- Advanced analytics and benchmarking
- Customer Hub and Helpdesk for support
- 350+ integrations (Shopify, WooCommerce, Stripe) plus full API
Marketing powered by real data
Klaviyo's defining strength is its data foundation. Because it unifies every customer's behavior into a single profile — what they bought, browsed and clicked — the marketing it sends is grounded in what people actually do, not broad guesses. That means genuinely personalized, timely messages: a product someone viewed but didn't buy, a replenishment reminder timed to their purchase cycle. For ecommerce brands, that behavior-driven personalization is what turns marketing from spray-and-pray into real revenue.
Automation that runs itself
Klaviyo automates the flows that quietly drive ecommerce revenue — welcome series, abandoned carts, post-purchase follow-ups, win-backs — across email and SMS together, triggered by real customer actions. Its newer AI agents push this further: Composer can build on-brand campaigns from a natural-language prompt and audit your flows and segments, while a Customer Agent resolves around 65% of support questions on its own. That's marketing and service increasingly running autonomously in the background.
One platform instead of a fragmented stack
Klaviyo's bigger pitch is replacing a tangle of separate tools — email tool, SMS tool, CDP, analytics, helpdesk — with one unified system where they share the same customer data. That unification is powerful: your support team sees the same profile your marketing does, and your campaigns, service and analytics all draw on one source of truth. Processing billions of events and API calls daily, with a 99.95% uptime SLA and SOC 2 compliance, it's built to handle that at serious scale.
Learn from every brand's data
Beyond your own numbers, Klaviyo's scale gives it a rare advantage: benchmarking. Because it processes billions of events across 205,000+ brands, it can show you how your open rates, conversion and revenue compare to similar businesses in your industry, so you know whether a result is genuinely good or just average. That context turns raw analytics into actionable direction — you can see where you're underperforming peers and focus your effort there, rather than guessing what "good" looks like in isolation.
Why choose Klaviyo
For consumer and ecommerce brands that want marketing driven by real customer data, Klaviyo is a market-leading choice. Its unified CDP, omnichannel automation, deep personalization, AI agents for campaigns and support, and 350+ integrations (Shopify chief among them) make it a practical way to turn customer behavior into personalized, automated marketing that drives repeat purchases — replacing a fragmented stack with one data-rich platform.
