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.

We've been using Klaviyo for a long time and have continued to stay with the platform because of its rich feature set, ease of use, and flexibility. More importantly, it consistently delivers a strong return on investment, making it a valuable part of our marketing strategy.

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.

Everything just works - from popup to purchase
We run a premium dog care store in Bulgaria and Klaviyo has become the backbone of our email marketing. The Shopify integration synced our subscribers, orders and events flawlessly, in both directions. We built a welcome flow with a discount code, an abandoned checkout flow and a signup popup, all connected to the store data without a single technical issue.
What impressed us most: the level of control. Smart targeting rules for forms (scroll depth, exit intent, excluding existing subscribers and checkout pages), per-message Smart Sending settings, and clean sync settings that just make sense. Support for a non-English store (Bulgarian forms, emails and error messages) worked perfectly too.
If you are serious about turning store visitors into repeat customers, this is the tool. Five stars, well earned.

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.

Great experience! The setup was straightforward, and I was able to connect my custom domain and create a professional business email for my Shopify store. Everything worked as expected, and the interface was easy to follow. Having a branded email address gives my store a much more professional appearance. Highly recommended for Shopify store owners who want a reliable custom email solution.

Klaviyo has been really easy to use for my store. The automations make a huge difference—especially the abandoned cart flow, which helps bring customers back without me doing anything. It’s a true set‑and‑forget system that saves me time so I can focus on other parts of the business.

Increased communication with our clients, converts to additional sales. Easy to use.

Excellent app with amazing support! Klaviyo is a powerful and reliable platform for Email Marketing&SMS. Special thanks to Anastasia and Mariyah for the amazing support. Great experience!

It's a great app, been using it for 2 years
