Klaviyo: Email Marketing & SMS

The platform functionality might be powerful, but the user experience is incredibly frustrating.

When encountering technical issues with dynamic variables in templates, there is absolutely no way to get basic support unless you upgrade to a paid plan. Worse, when trying to log into the Klaviyo Community to post a question, the website gets stuck in an infinite login redirect loop due to cross-domain cookie issues.

As an e-commerce merchant, spending hours fighting broken authentication logic and paywalled support instead of resolving a simple issue is completely unacceptable. Highly disappointed with the customer experience.

It’s okay but when trying to cancel it makes it extremely hard. I deinstalled the app wanting to stop it, and got an email that it will automatically bill me due to maxing the amount of subscribers. Logging it to cancel the account it so challenging and I still don’t know if it’s cancelled properly.

Wir nutzen die App für E-Mail Marketing und das funktioniert auch sehr gut. Was mich aber stört ist die Preispolitik. Für ganz kleine und große Unternehmen sind die Preise in der Höhe nachvollziebar, aber gerade für Unternehmen die am Wachsen sind ist die App extrem teuer. In diesem mittleren Bereich steigen die Preise (Stückkosten) so extrem steil an, dass es wirklich nicht mehr schön ist. Ich finde die Strategie unfair, große Unternehmen zu belohnen und Unternehmen in der Wachstumsphase derart zu belasten. Für Interessierte empfehle ich unbedingt, die Preise genau durchzuspielen.

Unfortunately, we can’t recommend Klaviyo for several reasons. Basically, you constantly get the impression that their only goal is to push customers into a higher plan and keep them there.

1. Many fake profiles are created that inflate the plan count.
2. Deleting profiles is very cumbersome—you have to create a segment to do it.
3. Even then, the option to delete is still missing, and we can only suppress the profiles. If deletion is possible, the option is very well hidden.
4. Support isn’t helpful; they write long messages that don’t make sense and refer you to confusing FAQs. Or they end the conversation while you’re still in the middle of following their instructions.
5. Overall, we’ve tried multiple times over the past few months to resolve our issues across various stores, but we haven’t gotten anywhere. We’re still on a higher-tier plan and haven’t been able to delete any profiles.

removed klaviyo because too expensive. Removing it has damaged my code and now shopify team are having to work to fix the problems. Avoid klaviyo like the plague!

This is not a user friendly app... maybe all email apps are the same. However, the AI 'help' used by Klaviyo runs around in circles and is a step above useless.

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

Klaviyo urgently needs to take inspiration from Canva because right now the editing experience feels outdated, clunky, and honestly exhausting.I’d honestly go as far as saying that Klaviyo is one of the worst apps I’ve ever used in my entire life when it comes to editing anything. The email marketing editor is unbelievably complicated for absolutely no reason. Nothing about it feels intuitive. Every simple task turns into a frustrating, time-consuming mess.

It genuinely feels like the product was designed by engineers who never actually had to create a real marketing email themselves. The UX is terrible, the workflow is confusing, and basic editing actions feel painfully overengineered. Instead of helping you move fast, the platform constantly fights against you.

What’s shocking is that email marketing should be simple in 2026. Apps like Canva proved years ago that powerful tools can also be clean, visual, and easy to use.

I never write negative reviews about apps. In fact, this is probably the first time in my life I’ve felt the need to leave one. But the experience was genuinely that bad. For a platform this expensive and this popular, the editor is embarrassingly bad.

i have already uninstalled the app, it is still charging my company card for service fee

"Unable to checkout. Try again later." Can't upgrade my account because of Klaviyo's system issue. Can't contact support until I upgrade. Can't upgrade because of a system error. Complete and utter joke.
