Services FAQ
What is a Klaviyo agency?
A Klaviyo agency is a retention partner that plans and runs email and SMS inside Klaviyo for ecommerce brands — flows, campaigns, segmentation, deliverability, and capture — so repeat revenue is not left to a part-time inbox. CartStrings is an e-commerce email marketing agency built for Shopify brands roughly $1M+ ARR that want that work owned end to end.
What retention services does CartStrings offer?
CartStrings offers Klaviyo account audits, lifecycle email automations (flows), email and SMS campaigns, popups and list capture, and deliverability work. Most engagements start with clarity on what is leaking, then build or fix the flows and campaigns that matter.
Who is CartStrings for?
Shopify ecommerce brands doing about $1M+ ARR that want a specialist email marketing agency — not a generalist shop treating email as a side channel. If you need a free diagnostic first, use the Free Klaviyo Audit.
How do we get started?
Start with a Free Klaviyo Audit for a prioritized look at flows, segments, and deliverability, or book a call if you already know you want an email marketing partner. Paid work is scoped after fit is clear.
