Klaviyo is built for stores whose email program runs on customer data. Its flow builder triggers on actions such as viewing a product, starting checkout, placing an order or a price drop, and it can also fire on a predicted next order date, which helps with replenishment reminders. Each flow can branch by cart value, VIP status, new or returning customer, location or lifetime value, and email, SMS and push can sit in the same sequence. More than 60 templates cover the standard store flows, and the newer Composer agent can draft campaigns and flows from a prompt. The free plan is a real working account with flows and segmentation, but it caps out at 250 active profiles and 500 emails a month, and full email support ends after 60 days. Paid prices were shown only in other currencies from our location, so check the calculator on Klaviyo's US page for your list size before you commit.
