Brickell Men's Products review for Klaviyo: Email Marketing & SMS

As someone else said, "Mailchimp is for sending newsletters, Klaviyo is for making money". This is an amazing app that has huge revenue potential for your business. It's relatively easy to set up (it's very powerful, so there is a learning curve), but their support are very eager to help you out. In a nutshell, for every action someone takes on your website, you can send them a personalized email relating to that action to either strengthen your relationship with that customer or generate more revenue from them. I don't think any Shopify store owner can afford not to use even the basic features of this app.
