Is there a free plan, or do I need to pay from day one?
Klaviyo offers a genuinely free plan with no time limit. It supports up to 250 active profiles, 500 email sends per month, and 150 SMS/MMS credits — with access to segmentation, automation flows, templates, and A/B testing included. Email support is available on the free plan for the first 60 days only; after that, you'll need a paid plan to reach support.
How does Klaviyo's pricing scale as my list grows — and are there any billing surprises I should know about?
Paid email plans start at $20/month for 251–500 active profiles, rising to roughly $150/month at 10,000 contacts and $720/month at 50,000. Since February 2025, Klaviyo bills based on total active profiles in your account — not just contacts you've recently emailed — and your plan upgrades automatically when you cross a threshold. Many merchants were caught off guard by this change; proactively suppressing unengaged contacts is the main way to keep costs down.
How deep is the Shopify integration — will it actually sync my store data in real time?
Klaviyo's Shopify integration is widely regarded as best-in-class. It syncs customer profiles, order history, product catalog, browsing behavior, and cart data in real time — in milliseconds — and supports Shopify Flow, meaning you can trigger Klaviyo actions directly from events inside your Shopify admin. Over 117,000 brands use Klaviyo and Shopify together.
How long does setup take — can I do it myself without a developer?
Most merchants can connect Klaviyo to Shopify and launch basic automations (welcome series, abandoned cart) without any developer help. The drag-and-drop editor, 60+ pre-built flows, and 160+ email templates mean you can go from install to first campaign quickly. Klaviyo Academy also offers courses and certifications for self-guided learning, though complex segmentation and custom flows do have a real learning curve.
Does it integrate with the other tools already in my stack — like ReCharge, Gorgias, or Meta Ads?
Klaviyo connects with 350+ integrations, including Shopify Flow, ReCharge, Aftership, Typeform, Meta Advertising, Gorgias, and TikTok Advertising — all listed directly on the App Store listing. It also natively connects with email, SMS, WhatsApp, and mobile push into a single unified customer profile, making cross-channel marketing possible without managing separate data syncs.
What do other merchants say about the support team and overall reliability?
On the Shopify App Store, Klaviyo holds a 4.6-star rating across 2,600+ reviews, with 85–89% being 4- or 5-star. Merchants praise responsive live chat support, knowledgeable CSMs, and comprehensive documentation. A recurring criticism is that support quality drops significantly on lower-tier or free plans — some merchants report difficulty reaching anyone until they upgrade to a paid subscription.
Does Klaviyo work for international or multi-currency stores?
Klaviyo's interface and campaigns support 10 languages including English, French, Spanish, German, Portuguese, Korean, Italian, Polish, Swedish, and Dutch. SMS and WhatsApp credit costs vary by country and region, and WhatsApp marketing messages are not currently supported for US phone numbers. For stores using Shopify Markets or selling cross-border, Klaviyo's geolocation and segmentation tools can help target by region, but international SMS pricing adds a layer of cost complexity to factor in.
