Find and organize STOQ profiles in Klaviyo

Identify the profiles STOQ syncs, build segments from their properties, and add new signups to any Klaviyo list with a flow.

Last updated

Every profile STOQ syncs to Klaviyo is tagged so you can find it, group it into a segment, and feed it into your lists and flows. STOQ doesn’t add profiles to a specific list on its own. To route new signups onto a list automatically, build a Klaviyo flow triggered by STOQ’s signup metric, shown below.

How STOQ tags profiles

Section titled “How STOQ tags profiles”

STOQ sets a source property on each synced profile, equal to your profile tag (default restock-rocket), plus these:

Property Meaning Example
source Profile origin (your STOQ tag) restock-rocket
StoqBackInStock Opted into STOQ alerts true
StoqAcceptsMarketing Marketing consent true or false
StoqCountry Customer country United States
StoqCountryCode Two-letter country code US
StoqLocaleCountry Locale and country combined en-US

You can view or change the tag in STOQ under Back in stock alerts > Settings > Integrations > Klaviyo > Profile tags.

Add new signups to a list automatically

Section titled “Add new signups to a list automatically”

STOQ emits a metric each time a customer signs up, so you can trigger a Klaviyo flow on it and add those profiles to any list.

  1. Create a flow

    In Klaviyo, go to Flows, click Create flow, and choose Build your own.

    Klaviyo Flows list page with a search box, Status and Tags filters, a Metric period of Last 7 days, and a table of flows (including Add stoq profiles to segment and a Live BIS flow). Toolbar buttons List, Analytics, Audit flows, Options and Create flow. Marker: 1 on the Create flow button.

    Klaviyo Flows / Create flow page showing Integrations (Shopify) and Channels (Email) filter chips and a Recommended for Artos software section with a Browse Abandonment template card and preview. Top-right buttons Automate Instagram activity and Build your own. Marker: 1 on the Build your own button.

  2. Set the signup trigger

    Set the trigger to the metric Customer signed up for alert (STOQ). On older connections that use a private API key, the metric is named Stoq - Customer signed up for alert. A flow’s trigger can’t be changed after the flow is created.

    Klaviyo Select a trigger panel on the Your metrics tab, listing STOQ metrics such as Back in stock alert (STOQ), Back in stock reminders, and Preorder metrics; the entry Customer signed up for alert (STOQ) is in the list. Markers: 1 on the Your metrics tab, 2 on Customer signed up for alert (STOQ).

    Klaviyo Confirm your trigger selection dialog warning that the trigger cannot be changed after saving, showing the chosen Trigger metric Customer signed up for alert (STOQ), with Cancel and Confirm and save buttons, over the dimmed Set up trigger panel.

  3. (Optional) Filter by marketing consent

    Add a profile filter of StoqAcceptsMarketing is true to keep only customers who consented to marketing. Skip it to include everyone.

    Klaviyo Set up trigger panel with the metric Customer signed up for alert (STOQ), Re-entry criteria set to Allow re-entry, a Trigger filters section (none applied) with an Add button, and a Profile filters section (none applied) with an Add button. Marker: an arrow pointing at the Profile filters Add button.

    Klaviyo Profile filters editor titled Edit profile filters, with a condition built from Properties about someone, the property StoqAcceptsMarketing set to is true, Type Boolean, plus OR and a delete icon and an AND button to add another condition.

  4. Add a List update action

    Drag in a List update action, choose Add to a list, and pick your target list. The list must already exist in Klaviyo.

    Klaviyo flow builder canvas with an Actions sidebar (Email, Text message, WhatsApp, Form, Customer Hub block; Property update, List update, Internal alert, Webhook; Time delay, Split). The flow shows a Trigger card (When someone Customer signed up for al…) and a List Update #1 card with a Set up list update button, marked Draft.

    Klaviyo List update details panel with List update name List Update #1 and Status Draft; under Select an action the Add to a list option is selected with a List dropdown, and a Remove from a list option is below. Marker: an arrow pointing at the Add to a list option.

  5. Set the flow live

    Set the flow to Live. New STOQ signups now join the list automatically.

    Klaviyo flow builder with the flow now showing a green Live badge beside STOQ in the breadcrumb; the Trigger card (When someone Customer signed up for al…) connects to a List Update #1 card reading Add to List with a Live status pill. Marker: 1 on the Update status button, top right.

    Klaviyo Update status drawer with a Preview flow card and a Flow status dropdown set to Live, plus Update status now (selected) and Schedule radio options, and Save and Cancel buttons at the bottom. Markers: 1 on the Live status dropdown, 2 on the Save button.

To find or group profiles you already synced, build a Klaviyo segment on the properties above, for example source equals your profile tag, or StoqBackInStock equals true.

Troubleshooting

Section titled “Troubleshooting”
No one is entering the flow

The trigger metric must be Customer signed up for alert (STOQ), or Stoq - Customer signed up for alert on a private-key connection. Confirm Klaviyo shows as connected in STOQ and that new signups are syncing.

The flow runs but no one lands on the list

The List update action is likely disconnected or the flow isn’t live. Reconnect the action, confirm it’s set to Add to a list with the right list, and set the flow to Live.

A segment on STOQ properties is empty

The source value in your condition must match your STOQ profile tag exactly. Check the tag under Back in stock alerts > Settings > Integrations > Klaviyo > Profile tags, and confirm Klaviyo shows as connected. If you changed the tag after syncing, older profiles keep the previous value, so match on StoqBackInStock equals true instead.

New signups take a while to appear

STOQ syncs the profile and emits the metric shortly after signup, and Klaviyo then processes the flow. Give it a few minutes.

FAQ

Section titled “FAQ”
Can I add STOQ profiles to more than one list?

Yes. Add multiple List update actions in one flow, or build a separate flow per list.

Does the flow respect marketing consent?

Only if you add the StoqAcceptsMarketing is true filter. Without it, everyone who signs up enters the flow regardless of consent.

Can I add profiles who signed up before I built the flow?

Yes. Open the flow and use Klaviyo’s option to add past profiles, or build a segment from the properties above and add its members to the list in bulk.

Can I export a segment of STOQ profiles?

Yes. Build a segment on the STOQ properties, then from the segment’s menu choose to export it as a CSV.

Where do I change the profile tag?

Under Back in stock alerts > Settings > Integrations > Klaviyo > Profile tags in STOQ.
