Klaviyo vs Kustomer

Klaviyo is a web marketing platform for communicating through email, SMS, RCS, mobile push, WhatsApp, and social marketing. Its tools include email automation, audience segmentation, landing pages, A/B testing, and lead capture forms. A helpdesk adds ticket management, customer context, omnichannel support, and AI automation; Klaviyo says its Customer Agent resolves 65% of questions autonomously. The app marketplace offers more than 350 integrations, and developers can build apps and integrations with APIs, webhooks, SDKs, and warehouse syncs. The Free plan costs nothing and includes up to 250 active profiles, 500 email sends per month, $5 of mobile messages per month, and $5 of Composer usage per month. Free access can remain available indefinitely while account limits are maintained, but sending may be paused or restricted if limits are exceeded. Free users receive full email support for the first 60 days. Klaviyo states that it is SOC 2 Type II certified and provides GDPR-related data processing measures and tools, with EU and US data residency. The company was founded in 2012 and is based in Boston, Massachusetts.

Kustomer is a customer experience platform for managing customer relationships across chat, email, voice, and social. It brings those interactions into a shared timeline and provides profiles that can hold custom objects and attributes such as purchase history and preferences. AI agents support customer service, while tools give human representatives context and suggested actions. CX teams can use Kustomer Architect to build, test, launch, analyze, and optimize AI experiences without writing code. Data Explorer returns plain-language answers, charts, and breakdowns, and the platform tracks real-time CX trends. Managers can review and approve AI actions; guardrails can send high-risk conversations to a human. The platform also includes a shared inbox, SLA management, help center, ticket automation, customer portal, and API access. It runs on Android, iOS, and the web. Pricing is on request. Enterprise and Ultimate are billed through Talk to Sales and have different limits for objects and tasks, brands, languages, webhooks, and API rate limits.
