Recent moves8 records

Expansion highlights6 records

Direct peers

• Mailchimp (Intuit): Mailchimp, owned by Intuit, is the most direct competitor to Klaviyo in SMB email marketing and automation. Both target ecommerce brands with freemium-to-paid PLG funnels, contact-based pricing, and similar feature sets (drag-and-drop builders, segmentation, behavioral automation). Intuit's deeper resources and QuickBooks/Commerce cross-sell create a comparable but better-capitalized competitor.
• Braze: Braze is a direct B2C CRM peer competing for mid-market and enterprise consumer brands with cross-channel messaging (email, SMS, push, in-app). Braze's strength in mobile-first engagement and real-time orchestration overlaps significantly with Klaviyo's omnichannel positioning, particularly for larger brands with mobile app presence.
• Iterable: Iterable is a cross-channel marketing automation platform serving B2C brands with email, SMS, push, and in-app messaging. It directly competes with Klaviyo for mid-market and enterprise customers, with comparable AI-powered orchestration, segmentation, and CDP capabilities, and a similar vertical focus on retail, ecommerce, and consumer brands.
• Attentive: Attentive is a leading SMS-first marketing platform for retail and ecommerce brands, directly competing with Klaviyo's SMS Marketing and SMS-Magic products. Attentive has expanded into email, making it a more direct omnichannel competitor, particularly for brands prioritizing text messaging as a primary channel.
• ActiveCampaign: ActiveCampaign is a customer experience automation platform serving SMB and mid-market customers with email, CRM, and automation features. It directly competes with Klaviyo in the SMB email marketing segment with comparable pricing tiers and PLG-style adoption, though with a less ecommerce-focused positioning.

Broad incumbents

• HubSpot: HubSpot is a broad marketing, sales, and service CRM suite that overlaps with Klaviyo's marketing automation and email products. While HubSpot targets primarily B2B with growing B2C ambitions, its Marketing Hub competes head-to-head for mid-market customers and benefits from significantly larger scale and a bundled product offering.
• Salesforce Marketing Cloud: Salesforce Marketing Cloud (including Account Engagement/Pardot and Commerce Cloud integrations) is the enterprise incumbent in B2C marketing automation. It competes for Klaviyo's enterprise tier with deeper CRM integrations and significantly larger scale, though at substantially higher price points and complexity.
• Adobe Marketo Engage: Adobe Marketo Engage is an enterprise marketing automation platform now part of Adobe Experience Cloud. It competes with Klaviyo's enterprise tier, particularly for B2B-adjacent use cases, and benefits from Adobe's broader creative, analytics, and commerce ecosystem through Adobe Experience Platform integrations.

Others

• Twilio (Engagement Platform): Twilio provides messaging infrastructure (including SMS and WhatsApp APIs) that Klaviyo uses as a sub-processor for SMS delivery. Twilio's Segment CDP and Engage products overlap with Klaviyo's CDP and customer engagement capabilities, making it both a partner and a potential competitor, particularly as Twilio expands its customer-facing marketing products.

Emerging players

• Zendesk: Zendesk is a customer service and engagement platform that increasingly competes with Klaviyo's Customer Agent, Customer Hub, and Helpdesk products. As Klaviyo extends from marketing into service workflows with AI-powered autonomous agents, Zendesk represents the most relevant incumbent for the customer service expansion, particularly among enterprise brands.
