Much easier to use than Mailchimp, thankfully Mailchimp ended their partnership with Shopify so that we got the experience of Klaviyo. Great service, amazing features that are really easy to use, and the flows are going to come in very helpful. The only problem was the fact that all orders came into the account as USD, but we needed them GBP. Support sorted this within an hour

Super simple but leaves you looking like a marketing guru. The integration of smart strategy is huge and take a lot of the thinking out of it. Only email platform to use in my opinion.

good app really, waiting for the customer return and turnover feedback. no campain sent yet. let 's wait

I just started using it and love it so far! Very easy to use, nice templates and great data analysis.

Launched my first campaign moments ago. Entire editing of the EShot took around 30 mins (very user friendly). I love how it integrates to shopify so well, all your products and contacts are imported. There's advanced segmentation and conditional customer journey. So far, very impressed.

Double opt in on free plan means you will have no sign ups. And there is no way around it. If you have a 3rd party sign up form (like Privy) Klaviyo will still send a sign up confirmation request once the address is synced to the list.
I don't mind paying for a good service, but not to a company that messes me up in such a sneaky way. Will sing up for a paid plan elsewhere.

Klaviyo are amazing. We have had it installed for years but kept on the free plan for the longest time. With the pending removal of Mailchimp from Shopify's ecosystem, Klaviyo was there every step of the way in bringing the most out of our marketing automation capabilities.

Our only regret was not starting earlier.

Klaviyo was BUILT for e-commerce and the advanced segmentation, syncing of Facebook Audiences and complex automation flows help get the most out of our marketing efforts.

Klaviyo is easy, allowing for complex thing such as feeds to supply dynamic content that is always up to date, personalisation and other things.

And it just WORKS with Shopify. They do most of the heavy lifting but aren't afraid of you customising its output.

They have our highest endorsement.

Just started Klaviyo after fiddling with Mailchimp for months. Loving it so far! Would definitely recommend.

Started using this app once mailchimp and shopify ended their integration. So far I'm loving it. Highly recommended!

Terrible. Had a sign up form on my pre-launched website. When I tried to notify the ones who had signed up that the site was live Klaviyo disabled my account and didn't let me notify them.

I'll have to email everyone one by one. Terrible service.
