About Klaviyo
Klaviyo is a marketing automation and customer data platform built primarily for e‑commerce brands. Businesses use Klaviyo to collect and unify customer data from their online store and other tools, then send targeted email, SMS, and push campaigns, as well as automated flows like welcome series, abandoned cart reminders, and post‑purchase follow‑ups. The company is headquartered in Boston, MA, and integrates with platforms like Shopify, BigCommerce, WooCommerce, and many others, offering segmentation, A/B testing, analytics, and revenue attribution tools to help merchants grow and retain customers.
A Klaviyo charge on your bank or card statement usually relates to a monthly subscription fee for email and/or SMS marketing services. Klaviyo offers a free tier for very small lists, and then paid plans that scale based on the number of contacts in your account and any SMS usage. You might see a recurring monthly charge for your plan, usage-based SMS overages, or prorated charges/credits if you upgraded or downgraded your contact tier mid‑cycle. In some cases, you may also see a temporary authorization when you first add or update your payment method.
If you don’t recognize a Klaviyo charge, first check whether your company or online store uses Klaviyo for email or SMS marketing, and log into your Klaviyo account to review the Billing section under Account > Billing. There you can see invoices, plan level, contact tier, SMS usage, and billing dates. If you still have questions, visit help.klaviyo.com to search the support center or contact support through in‑app chat or email (for eligible plans). Common resolutions include identifying which store or brand the account is tied to, adjusting or cancelling a subscription, or requesting clarification on SMS usage or contact‑tier changes.
