Klaviyo: Email Marketing & SMS

We've had a great experience with Klaviyo so far. It's genuinely user-friendly most of the core features are easy to find and use without much of a learning curve.Would recommend it to anyone looking for an intuitive email/SMS marketing tool

Enjoying my email platform experience with Klaviyo. The customer service is amazing, they respond very quickly and very helpful.

Very helpful app, especially with new Composer in place, which allows you to audit flows and much more! Highly recommended.

Running a small brand on my own, I needed an email tool that wouldn't slow me down, and Klaviyo has been exactly that. It's incredibly intuitive. I set up a welcome flow, a signup popup, and an abandoned cart sequence without needing any tutorials, just by clicking around. The interface is clean and friendly, and everything sits where you'd expect it to. So far I'm genuinely happy with it and can already see it helping the store.

Update*

After our feedback, Klaviyo team reached out to us and solved our problem. Hope they solve this problem for everyone. Thank you Klaviyo team.

If giving this app 0 stars were possible, we would seriously consider it.

Seems like entire system built to rip you off.

We paused our use of Klaviyo for a while. When we returned, our paid plan had been deactivated, which was understandable. However, we then encountered a billing loop that made it impossible to clean up our account without first paying for profiles we do not intend to use.

Here is the issue:

1. Without an active plan, we cannot suppress profiles manually, in bulk, or through the API.
2. We also cannot reactivate the account on the free plan because the number of active profiles exceeds the free-tier limit.
3. The only option presented is to purchase a paid plan covering the entire existing profile count first, even though the purpose of reactivating the account is to suppress inactive profiles and reduce that count.
4. If we pay for the oversized plan, suppress the profiles, and then downgrade, the initial payment is not refunded or credited toward future invoices.
5. We also tested bulk suppression through the API. The API accepted the request and marked the job as complete, but all profiles were skipped:

* Total count: 100
* Completed count: 0
* Skipped count: 100

6. We found similar reports in Klaviyo’s community forums, but we could not find a practical self-service solution.
7. Access to customer support is also restricted without an active paid plan, which makes resolving the issue even more difficult.

This creates a frustrating circular problem: we cannot suppress profiles without reactivating the account, and we cannot reactivate the account without first paying for profiles we specifically want to suppress.

Requiring customers to pay for an oversized plan before allowing them to remove inactive profiles feels unfair and unnecessarily restrictive. Businesses should not have to pay a substantial fee simply to regain access to basic account-cleanup tools.

They make it impossible to clear all inactive profiles to susspended. This way they can keep increasing your monthy charge due to profiles. The app is also VERY HARD TO USE. We are an IT company and we find it backwards and HARD. FIND ANOTHER SOLUTION!!!!!! . Klaviyo is outdated and bad

Fast responding customer service. They handle all issues with professionalism and care. Easy to use software.

works well but some time required to set up

Klaviyo is highly intuitive software, and I appreciate how proactively the application operates.
