Been using Klaviyo for 4 years now, it has grown and evolved and keeps getting better. Best marketing $$$ we have ever spent.

Customer support is good, flows and automations will make you money.

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!

Great tool, excellent customer support. A lot of technical things to learn before you can effectively use it for the best results. But it seems there is a solution to almost every issue that occurs. Email deliverability is especially tricky, but there a many great tools provided by Klaviyo.

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!
