What it is
Klaviyo is a web-based marketing platform for coordinating customer outreach across email, SMS, RCS, mobile push, WhatsApp, and social channels. Its tools include email automation, audience segmentation, landing pages, A/B testing, and lead-capture forms. The helpdesk combines ticket management, customer context, omnichannel support, and AI automation; Klaviyo says its Customer Agent autonomously resolves 65% of questions. The app marketplace offers more than 350 integrations, and developers can build connections using APIs, webhooks, SDKs, and warehouse syncs. The Free plan costs nothing, billed monthly, and includes up to 250 active profiles, 500 email sends per month, and $5 each for mobile messages and Composer usage per month. It can remain available indefinitely while account limits are maintained, but sending may be paused or restricted if those 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 measures and EU and US data residency.
