Klaviyo Acceptable Use Policy

This document is Klaviyo's Acceptable Use Policy (AUP), which governs how customers and users may use Klaviyo's marketing automation platform, including its email, SMS, WhatsApp, and related messaging services, and is incorporated by reference into Klaviyo's broader Terms of Service. The agreement states that users are prohibited from sending unsolicited messages, using purchased or rented contact lists, transmitting content that is deceptive, harassing, or illegal, and from using the platform for categories including adult content, firearms, cannabis, payday lending, and multi-level marketing without explicit written permission; the terms also authorize Klaviyo to suspend or terminate accounts that violate the policy, with or without notice. The policy's enumerated list of restricted content categories and industries creates operationally significant access conditions for businesses in regulated or sensitive verticals, and the terms assert Klaviyo's right to make final determinations on compliance, which may limit user recourse in account enforcement decisions. The AUP engages CAN-SPAM, TCPA, and CASL for messaging compliance, as well as GDPR and CCPA for data handling obligations referenced in related policies; enforcement exposure varies by jurisdiction, particularly for SMS marketing practices subject to TCPA in the United States and ePrivacy Directive requirements in the EU. Businesses operating in restricted categories or relying on third-party contact lists should evaluate their onboarding and list acquisition practices against the explicit prohibitions stated in this document.
