    What you can do with it

    How a campaign calls a Klaviyo segment

    A Klaviyo segment is a group of profiles defined by conditions: it grows as people meet them and shrinks as they stop, updating in close to real time (Klaviyo). Lists are different: they are static, and people join them through sign-up forms, imports or by hand (Klaviyo on segments and lists).

    When you create a campaign in Loop Voice, choose the Klaviyo segment as its audience. Campaigns are in beta. Then:

    • Numbers on the do-not-contact list are excluded automatically, and that list is honored by every flow, campaign and text.
    • You set the campaign time zone, the daily calling window and the pace in calls per minute; calling windows apply in each customer's own time zone.
    • A credit estimate shows before launch. If credits run out, the campaign pauses and resumes when you top up.
    • Frequency caps, set per agent, limit how many calls one customer gets per week, month, quarter, six months or year.

    Revenue is reported per campaign and tied to the Shopify order number.

    Build a segment Loop Voice can call

    Two conditions from Klaviyo's segment conditions reference help here:

    • Properties about someone: Phone number is set, so every profile in the segment has a number to call.
    • If someone is in or not in a list, to call the members of a list through a segment.

    Klaviyo segments pull from every profile in your account, including people who have not opted in to marketing (Klaviyo), so a "Phone number is set" segment can include people who never agreed to calls. Call only customers who agreed to calls. Klaviyo notes that being in a list does not by itself mean a profile has consented to marketing, and our guide to calling rules covers consent for AI calls.

    Abandoned checkouts belong in a flow

    Klaviyo segments feed campaigns. For abandoned checkouts, use a Loop Voice abandoned cart flow instead: it starts on the store event and stops the moment the customer orders, says stop, or after a negative call. To run those calls next to a Klaviyo abandoned cart flow without double messages, follow our Klaviyo timing plan.

    FAQ

    Common questions

    Do I need a Klaviyo API key?

    No. You authorize Loop Voice on Klaviyo when you connect, and there is no key to create or paste.

    How do I call a Klaviyo list with Loop Voice?

    Campaigns use Klaviyo segments as their audience. To call a list's members, build a segment in Klaviyo with the condition "If someone is in or not in a list" and choose that segment as the campaign audience.

    Are do-not-contact numbers left out of a Klaviyo segment campaign?

    Yes. Numbers on the Loop Voice do-not-contact list are excluded automatically. A STOP by text, a "don't call me" on a call or a carrier block puts a number on that list before the next step runs.

    How many credits does a Klaviyo segment campaign use?

    About 1.5 credits per answered conversation, and a call nobody answers uses none. Loop Voice shows a credit estimate before launch, and the campaign pauses if credits run out.
