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.

Frequently Asked Questions

What types of Klaviyo charges typically appear on my bank or credit card statement?

Most Klaviyo charges are monthly subscription fees based on your contact tier and whether you’re using email only or email + SMS. You may also see usage-based SMS charges if you send more text messages than are included in your plan, as well as prorated adjustments if you change your plan mid‑cycle. Charges usually appear under “Klaviyo,” “Klaviyo Inc,” or similar wording on your statement.

How does Klaviyo’s pricing work and what are common charge amounts?

Klaviyo pricing scales with the size of your contact list and your communication channels. There is typically a free tier for up to a small number of contacts and monthly email sends, then paid email plans that increase in price as your contact count grows (for example, from a modest monthly fee for a few hundred contacts up to higher tiers for larger lists). If you add SMS, you’ll pay either a combined email + SMS plan or pay‑as‑you‑go rates based on message volume and country. Exact pricing and your current rate are listed in Account > Billing inside Klaviyo.

Why did my Klaviyo bill increase this month compared to last month?

Your Klaviyo bill often increases when your active contact count moves into a higher tier or when your SMS usage goes up. If you grew your subscriber list, imported new contacts, or ran high‑volume SMS or email campaigns, your plan may have automatically adjusted to the appropriate tier. You can see a breakdown of your plan, contact count, and SMS usage by visiting Account > Billing > Invoices in your Klaviyo dashboard.

How do I cancel or downgrade my Klaviyo subscription to stop future charges?

To cancel or downgrade, log into your Klaviyo account and go to Account > Billing. From there, you can change your plan, move to a lower contact tier, or close your account following the on‑screen steps. Changes generally take effect at the next billing cycle, so you’ll keep access until the end of your current period; be sure to export any data you need before fully closing the account.

How can I request a refund or dispute a Klaviyo charge I don’t recognize?

First, log in and check Account > Billing > Invoices to verify what the charge covers (plan change, SMS usage, contact-tier increase, etc.). If you still believe the charge is incorrect or you don’t recognize the account, contact Klaviyo support through the help.klaviyo.com portal or via in‑app support if you’re on an eligible plan, and include the last four digits of the card, charge date, currency, and amount. Klaviyo reviews refund requests case by case, usually focusing on billing errors rather than usage of the service, and may issue credits or refunds where appropriate.

Why do I see a small or temporary Klaviyo charge or authorization on my card?

When you add or update a payment method, Klaviyo (through its payment processor) may place a small temporary authorization to verify your card. This can appear as a low dollar (or equivalent) pending charge, which should automatically fall off your account within a few business days and not post as a final charge. If an authorization remains pending for an unusually long time, contact your bank or card issuer first, then Klaviyo support if needed.

How can I confirm which business or store in my company is linked to a Klaviyo charge?

If your organization manages multiple brands or stores, you may have several Klaviyo accounts. Log into Klaviyo and check the account name and connected integrations under Integrations to see which e‑commerce platform or site is linked. If you’re unsure which login is associated with the charge, search your work email for “Klaviyo” onboarding or billing emails, or ask your marketing/IT team who manages email and SMS campaigns.

What should I do if I no longer use Klaviyo but I’m still being billed?

You may still have an active subscription even if you stopped sending campaigns. Log into your Klaviyo account and go to Account > Billing to verify your plan status; cancel or downgrade there to prevent future renewals. If you don’t have login access or the previous account owner has left your company, use the account recovery options on klaviyo.com or contact support via the Help Center with proof of ownership so they can help you regain access and adjust billing.
