## About

CartStrings is a Klaviyo-focused retention partner for Shopify brands. We help operators past early stage — roughly $500k+ annual revenue — turn email and SMS into a reliable revenue system, not a campaign treadmill.

Work centers on the lifecycle that actually moves money: welcome, browse and cart/checkout abandonment, post-purchase, winback, segmentation, deliverability, and list hygiene. We care about flow-attributed revenue and repeat purchase behavior, not vanity open screenshots.

We are especially at home with specialty retail and camera/photo brands — higher AOV, longer repurchase cycles, education-led journeys — where copying a replenishment DTC template usually fails. If you want a straight diagnosis first, start with a free Klaviyo audit on cartstrings.com; implementation is a separate conversation.
