A campaign calls a Shopify or Klaviyo segment once, inside the window you set: restock alerts, launches, early access and winback. Campaigns are in beta.
CityMan USA uses Loop Voice calls for restock reminders.
The short answer
An outbound campaign is a one-off batch of calls to a segment you choose, where a flow runs every time a store event happens. In Loop Voice you pick a Shopify or Klaviyo segment, set the time zone, daily calling window and pace, and see a credit estimate before launch; every call is attributed back to the campaign. Campaigns are in beta, and our benchmark doesn't report them separately yet.
Loop Voice agent
Illustrative conversation
Agent
“Hi Jordan, it's Alex, an AI assistant calling from [Store]. If you'd rather not get these calls, just say stop. The jacket on your waitlist is back in your size, and we're telling the waitlist first. Want me to text you the link?”
Customer
“Yes, please. Is that the black one?”
An illustration, not a recording. Real calls are in the call library.
A launch email lands next to every other promotion and leaves the customer to do the work. A call reaches the customers most likely to care, answers the question between interest and an order, and texts the link while they're still on the phone.
Pick a Shopify segment, abandoned checkouts, inactive customers or a Klaviyo segment. Loop Voice can also build a Shopify segment from a plain-English description.
Give the agent the news, the product details and one action, such as texting the product link, and add the facts to the knowledge base so it can answer questions.
Choose the campaign time zone, the daily calling window and the pace in calls per minute. Campaign windows apply in each customer's local time.
Loop Voice shows a credit estimate before launch and leaves do-not-contact numbers out. If credits run out, the campaign pauses and resumes when you top up.
Every call is attributed to the campaign that made it, and orders to calls by Shopify order number.
A flow runs on its own every time a store event happens: a checkout is abandoned, an order is fulfilled, a second order comes in. A campaign runs once, to a list you chose, on the schedule you set. Use flows for recovery and post-purchase calls, and campaigns for news.
Both honor the same do-not-contact list. Frequency caps are set per agent, so if a flow and a campaign use different agents, check that a customer in both won't get more calls than you'd accept.
Give each campaign one job: tell the customer the news and offer one thing, usually a texted link. Put your store's name in the first sentence, turn on the guardrails that have the agent say it's an AI when asked and respect refusals, and let a no end the offer.
Write the opening around the customer, not the catalog. Campaign calls start with what Loop Voice knows about the customer, including any cart and their local time, so the agent can open with the product they wanted instead of a general pitch.
CityMan USA, a streetwear store, uses Loop Voice to "remind customer when we restock products," in its founder's words. Drops sell out, so the call carries real news: the piece is back, sizes are limited, and the link arrives by text while the customer is still on the phone.
On its calls, CityMan USA found that telling customers their size was running low converted best, and its calls also help customers pick the right size (CityMan USA story).
Campaign calls use credits only when someone answers, about 1.5 credits per answered conversation. Example: if 15.9% of the segment picks up at least once, as shoppers did across September's abandoned checkout and post-purchase calls (often after several attempts), a 2,000-customer segment would produce about 318 answered conversations, or about 477 credits. The credit estimate before launch shows your own number.
Consent applies to campaigns as much as to flows. Build the segment from customers who agreed to calls and re-check it right before launch; our guide to calling rules covers the wording.
Choose the caller ID with care. In September, calls from a brand's own dedicated number were answered 7.3% of the time, against 5.3% for local-presence Super Number calls (benchmark), and our caller ID guide compares local and toll-free numbers.
Size, color, availability and delivery, answered from your catalog and site.
Sent during or after the call, so the customer can buy on the spot.
A customer who isn't interested is thanked and left alone; one who asks not to be called goes on the do-not-contact list.
Every call is tied to its campaign, and orders to calls by Shopify order number.

“Loop has been very helpful to convert abandoned cart and remind customer when we restock products, helps them find the right size, and even suggests pieces that go with what they were looking at to increase the AOV.”
