Klaviyo Pricing

Klaviyo’s pricing is based on your number of active contacts.

Every plan includes the same features. You just pay more as your list grows.

Bezpłatny plan: Yes — 250 contacts, 500 emails, and 150 SMS credits per month.

Gwarancja zwrotu pieniędzy: No refund policy. But the free plan lets you test before you pay.

📌 Notatka: The cost goes up based on your active profile count. At 1,000 contacts, email costs about $30/month. At 10,000 contacts, expect to pay around $150/month.

Is Klaviyo Worth the Price?

Here’s my honest take on the cost.

For small stores with under 1,000 contacts, Klaviyo is very fair.

The free plan covers the basics. Paid plans start low.

But once you pass 10,000 contacts, the price jumps fast.

You’ll save money if: Your email campaigns drive strong revenue and you keep your list clean.

You might overpay if: You have a big list with lots of inactive contacts you never email.

My Experience with Klaviyo

Here’s what actually happened when I used Klaviyo:

The project: I set up Klaviyo for a Shopify store selling fitness gear.

Timeline: 90 days of active use.

Wyniki:

What surprised me: The sign up process was fast. The Shopify integration pulled in all my customer data in under 5 minutes. I was sending my first targeted campaign within an hour.

What frustrated me: Not gonna lie — the pricing model confused me at first. I didn’t realize Klaviyo charges based on total active profiles, not just the people I email. Some users have reported issues like unexpected charges when their lists grow.

Would I use it again? Yes. Of course, no tool is perfect. But for ecommerce, nothing else I tested matched its ability to turn customer data into sales. The efficiency gains alone saved me 5+ hours a week. The ROI covered the cost many times over.

I also appreciated how Klaviyo collects customer feedback through its Reviews feature. It helped improve the store’s conversion rate.

My verdict: After 90 days, Klaviyo earned its spot as my go-to marketing platform for ecommerce clients.

The automation, segmentation, and analytics are the best in class.

Yes, the cost can climb. But the revenue it drives makes it worth every dollar.

Klaviyo is best for serious store owners ready to grow faster.
