Klaviyo Acceptable Use Policy

This document sets out the rules for what you can and cannot do when using Klaviyo to send messages and collect data. You must only contact people who have genuinely consented to hear from you, keep unsubscribe options working, and avoid promoting certain categories like cryptocurrencies and gambling. If Klaviyo decides you have broken these rules, it can cut off your access immediately and without owing you anything.

Klaviyo's Acceptable Use Policy establishes the conditions under which users may and may not use its platform, imposing affirmative obligations and categorical prohibitions across content, contact list composition, data handling, and messaging conduct. Users are required to obtain affirmative consent before collecting individual information or sending communications, maintain functional unsubscribe mechanisms, and comply with all applicable legal and industry regulations governing SMS/MMS, email, and mobile marketing. The policy categorically bars promotion of cryptocurrencies, gambling services, and jurisdictionally illegal substances via SMS/MMS, and prohibits the solicitation, storage, processing, or transmission of EU GDPR and UK GDPR special category data. Klaviyo reserves the right, in its sole discretion and without liability to the user, to immediately suspend, terminate, or limit access to its services upon a determination that the policy has been violated.

As a recipient of messages sent through Klaviyo, your consent is required before your information may be collected or before you may be messaged, and senders are prohibited from contacting you after you have unsubscribed. Unsubscribe functionality must be kept visible and working — senders cannot block or obscure it. If you have unsubscribed from a sender's messaging program, that sender is prohibited from continuing to message you through Klaviyo.
