Klaviyo is a great CRM with lots of features to help your business grow steadily while keeping track of all your KPIs. I wish I had known about it right from the beginning of my business. I also really appreciate that they keep it free while you're learning to use it - huge help to a small business.

It's a great app, but it has learning curve. If you have some time and patience, you can learn to use this app to benefit you and your business. It will take some time, but it can help you build your business.

I've been using Klaviyo with my shopify store for the last 18 months. I LOVE it.
I'm not that confident with technology but I have found their resource page super helpful and any time I have had a question (there have been a lot!) the team have always been quick to help me, they have even checked the set up of things for me.
I would HIGHLY recomend this to anyone who has a shopify store.

Highly Recommend. I have seen other email marketing apps in use and have personal experience with them, and Klaviyo is definitely the best by far. Aweber, Mailchimp, and Constant Contact do not have all the great features and ease of use like Klaviyo does.

The BEST email marketing software there is. We've tried many a few years ago, from Mailchimp to MailerLite, but nothing compares to Klaviyo. They are SO advanced! It has all the functions that we need as an e-commerce brand, both technical and design-wise. We've used it for 2 years and will keep using it forever!

The support I received from Miranda was wonderful! She went above and beyond in providing both education on site setup and also helping me find workarounds to get the outcome I was looking for. Would highly recommend reaching out to support with any questions!

SHE STREET has absolutely loved using Klaviyo, our revenue has increased by 338% in the last 2 years and we have reached more customers than ever.

The automation flows are perfectly set up which convert into sales and nurture our loyal customers, integrated with API's and SMS marketing.

Overall we are very satisfied with the service of Klaviyo.
