Klaviyo: Email Marketing & SMS

Klaviyo urgently needs to take inspiration from Canva because right now the editing experience feels outdated, clunky, and honestly exhausting.I’d honestly go as far as saying that Klaviyo is one of the worst apps I’ve ever used in my entire life when it comes to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.

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.

"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.

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 Klaviyo is outdated and bad

Extremely unhappy. Klaviyo is an OK email service, it is not super user friendly or smooth, it get's the job done.

Last year, my monthly price went from 80usd to 150usd.
And if I pause and resubscribe, it would be 200usd.

That is a 250% price increase.

During slow periods now, I cant keep my costs low, because then they will squeeze more money from me.

I would be very cautious picking klaviyo today.
They are in a phase now of just capitalizing the living hell out of their customers.

I am looking very hard to get out, and never come back. My energy to trust the company even if they adjust the prizing in the future would not be there.

So be cautious, if you get on their payroll, they will use you as hard as they can, and it is probably not great for either your or their business long term.

they are moving into a charge method when they want to charge you like they do provide the sales, but they really don't. They help send emails, the rest of all services are nothing unique at all. Meta owns their traffic and sells it to you. Klaviyo helps you communicate with your costumers, but they want to charge you like they also own the traffic.
But they don't.
Your customer lists are yours.
Not klaviyos.
They do not bring this value.

Be careful, and if you sign up, get ready to get used as hard as they can to get all the money out of you. You will end up in a annoyed frustrated position, the more dependent you get on them, the more they will take advantage of you as time goes by.
Think of it like telling a secret to your best friend, and then they will start blackmailing you not to tell it to somebody else, that is the feeling you will have in partnering with klaviyo.

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.

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

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.

Can literally never get Klaviyo to do what I need it to do. So disappointed to spend eleventy billion dollars a month on this. Just today, created a segment in Shopify to import to Klaviyo and it shows up in Klaviyo with ZERO people on it.
