I had the pleasure of exchanging with Daniele, and I couldn’t be more satisfied with the support I received. She was sweet and helped me resolve my issue quickly. Daniele made the whole process feel smooth and stress-free, and her friendly demeanor made me feel supported throughout. I highly recommend her for anyone needing assistance! Overall, the platform is easy to use, and the automation features have really streamlined my email marketing efforts. I especially appreciate the ability to create personalized flows for new subscribers, like the welcome discount for my newsletter. The support team has also been super helpful and responsive, making the setup process smooth. Highly recommend Klaviyo for any Shopify store owners looking to boost their email marketing game!

so far so good! Customer service is amazing as well whenever I've been stuck! Moved from Mailchimp and haven't looked back.

This can be a complex app to use but they provide free videos to help you along. I love that they offer classes throughout the year to sharpen your skills. I took one several weeks ago on something I've used for a while. I learned features I've never explored before and have implemented them into my weekly email campaigns! Love this app & highly recommend.

Knocks Mailchimp clean out of the water. Easy to use and effective integration with Shopify. First class support. What more could you want?

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'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.
