Fast and wonderful experience

Fun and professional tool to use to keep in touch with your customers and to expose you to new customers.

This app is really well done and the support is phenomenal. I'm a beginner when it comes to everything email marketing and I've been able to place all my automation emails and email campaigns. It has taken some time, but I can't say enough about the support that is given with real people, any time of the day. I recommend 100%

I cannot recommend Klaviyo enough, it is simply a fantastic tool for email marketing needs. Their support is top notch, very knowledgeable and efficient.

We love using Klaviyo for our online business needs.

I'm new to email marketing, and Klaviyo has been so easy to use. The platform is beginner-friendly, and the email templates and analytics make it simple to create and track campaigns. The Flows, Campaigns and Popups are super easy to create, edit and manage. I don’t use SMS, but the email tools alone are great for my business. Highly recommend Klaviyo to anyone starting out with email marketing!

Is this fraud?- Klaviyo Secret Sending Limits & Poor Transparency — Be Careful I’ve used Klaviyo for over a year and feel other Shopify merchants deserve a heads-up about something Klaviyo never discloses: Klaviyo will charge you for contacts that it will, without your knowledge or consent, refuse to send your emails to if they deem that contact is unlikely to open/click your email. Klaviyo takes your money then quietly gates or throttles your campaign sends, meaning your emails simply do not reach your subscribers — even though you’re paying full price for that list size. In my case, I had an 8k active list (with 30k suppressed), and Klaviyo still withheld delivery of many campaigns. Open rates were low because emails weren’t actually reaching inboxes, not because of strategy or content. Klaviyo’s dashboard shows “Poor” reputation, but the platform does not explain that this means your send volume will be internally limited. Klaviyo support misdirects you into thinking its all about YOU, the quality of your emails, etc... while not telling you that it's also because they just don't send your emails (their discretion), period. This makes recovery nearly impossible. You’re stuck paying for a list you cannot fully email, with no straightforward path to fix the issue and no warning that this is happening behind the scenes. Klaviyo can be powerful, but this lack of transparency seriously undermines trust. After switching providers, my deliverability improved immediately — confirming the issue wasn’t my content or audience. If you’re a Shopify merchant whose income depends on reliable deliverability, be aware of Klaviyo’s undisclosed internal limiting system. It can cost you months of lost revenue, while you’re still paying for contacts you can’t reach. Someone should really investigate this practice, as it seems like a class action waiting to happen.

Klaviyo s'intègre parfaitement à Shopify et permet vraiment un contrôle inégalé sur le marketing par courriel.

Super user-friendly and incredibly helpful!

Very good

A lot to learn but our systems have definitely improved since using Klaviyo. The help and tutorials and live webinars are so good. I always get the answer i need! Love it

Very interesting app. Very well made and structured. Easy to use. Solves all email marketing & SMS needs. Rich content and suggestions that make using it very productive. I had a minor problem with emails not sending that I couldn’t figure out. The support team was very helpful. Very quick response. They catered to my questions. And even shared solving the issue with the Klaviyo team as it was somehow intriguing. Thank you Andy for your help. Thank you Najah for finding what the problem was.

My revenue is increasing every day. Wish I had done this much sooner. I resisted Klaviyo for quite a while, but I'm so happy with it now that I took the time to learn how to use it.
