How do we leverage the front-end Identify API to handle when users log in and log out within a Single-Page Application (Angular) without refreshing the page? It seems that the 'identify' method is having issues being recognized properly when called multiple times per page load.

I am creating a call via = https://a.klaviyo.com/api/profiles?additional-fields[profile]=subscriptionsWith the body as follows -- the profile is being created but not subscribed. What am I doing wrong? How can I subscribe the user to a specific list too with this call?data: { type: "profile", attributes: { email: email, properties: { signup_date: created_at, } }, subscriptions: { email: { marketing: { can_receive_email_marketing: true, consent: "SUBSCRIBED", consent_timestamp: created_at } } } }, 

I have synchronized Klaviyo audiences with Google Ads for better targeting, but I see that the match rate is only 10-15%. Does anyone have experiences with this and a solution to increase the match rate?

I recently downgraded to a free plan, as I don't send many emails and currently only have 22 subscribers. I had read that my flows would then be paused, but that I would just have to put them Live again myself. But I can't do that? The box is just greyed out and I can't do anything.Is it really right that you have to pay to keep your flows running?

We recently got the notice around the new guarantees around the events API:We are reaching out regarding an upcoming change to Klaviyo’s events APIs. Starting on July 31, 2025 Klaviyo will be updating the attribution data freshness on our events APIs to a 3-hour SLA for improved system performance and data accuracy. If you are leveraging attribution data from these affected APIs, we recommend you update your usage of the events APIs to reflect the updated attribution data freshness prior to the cutover date to avoid any disruption to your integration. The affected endpoints are:Get EventsGet Event We had a few follow-up questions about this:Do you know if attribution data even on prior versions of the API might be stale when retrieving event data? How do these changes impact the webhook API endpoints, if at all? Do you know if opens/clicks also have a certain window of time where they also lack attribution data with regards to the source email?Thank you!

 The article “How to segment by customer lifetime value (CLV)” states something that I don’t find to be true anymore which is:“Exporting CLV data can allow you to further analyze and predict the behavior of different groups of customers. In addition to your CLV and predictive analytics values, you'll be able to export Churn Risk Prediction. Churn risk will be exported into your CSV as a number between 0 and 1.”I see each profile shows me predictive analytics, including “Churn Risk prediction” which tells me that my client has enough data to determine predictive analytics. However, When I try to export a segment via CSV, there are no property options to select for export that has anything to do with “Churn Risk”. The only predictive properties I have options to select for export or in segment definitions are the following:Historic Customer Lifetime Value Historic Number Of Orders Average Order Value Average Days Between Orders Predicted Number Of Orders!--> Predicted Customer Lifetim

Hello, tow week ago I started getting 100s of spam emails joining my newsletter per hour. It seems to be the same person… the email address starts with the same name with then a string of numbers and letters. They literally join my email list several times per minute! They have added over 8000 emails to my list in just a couple weeks. I have surpassed all of them, and now turned on double authentication when someone joins my list. But is there any other way to stop this? Has anyone else had this happen? Thanks, Jason V.

Hi everyone,I previously created a catalog using this guide, formatting the data in JSON.Here’s an example of a first product in my custom feed:{ "id": 322442, "title": "Bench", "description": "Bench", "link": "https://sample-url.com/bench", "price": "50.0", "categories": ["Test"], "image_link": "https://sample-url.com/files/8/288/2/326092/640x640.jpg", "inventory_quantity": 9, "sku": "BENCH123"}All products were successfully synced.The API Get Catalog Items returns the list of items as expected.Here’s an example of one of the items in the array:{ "type": "catalog-item", "id": "$custom:::$default:::322442", "attributes": { "external_id": "322442", "title": "Bench", "description": "Bench", "price": 50.0, "url": "https://sample-url.com/bench", "image_full_url": "sample-url.com/files/8/288/2/326092/640x640.jpg", "image_thumbnail_url": "sample-url.com/files/8/288/2/326092/640x640.jpg", "images": [], "custom_metadata": {}, "published": true, "cre

We use Klaviyo with a custom HTML template.We’ve created several universal blocks, including a product block that contains the product name, price, button (with URL), and image.Now, I want to create a universal block for use in flows — for example, a “next best product” block. I want the product title, price, URL, and image to be loaded dynamically based on the customer receiving the email. For one customer this might be Product A, and for another it could be Product B.We use WooCommerce and the product catalog is connected.Does anyone have any idea how this can be done?See screenshot for what I tried. 

The product images on my website have varying aspect ratios—some are 1:1 while others are 2:3. When using product blocks, whether dynamic or static, is there a way to automatically enforce a 1:1 aspect ratio for all displayed images?

I’ve been using midmimi for years for email marketing and they were bought by godaddy who is doing just a miserable job of implementation and support. Because one of my 5 web business is a t shopify Id like to integrate Klaviyo. I want to upload my entire database so I can send occasional newsletters to my 20K+ list. Will Klavio handle this size and allow me to send a campaign to all my customers? Thank you!

Hey Everyone, i have setup my Abandoned Cart Flow for new customer in specific collection like this. So many passed, this flow dont working, and dont sent email to anyone.If anyone know this problem, please help meThanks for read!

I have a few questions regarding suppression behaviour in Klaviyo:Yesterday, I mistakenly bulk-suppressed a group of contacts. I immediately reversed the action by unsuppressing them. These profiles now appear as Subscribed in Klaviyo.However, when I sent a campaign this mornin, these contacts were skipped, even though they were technically eligible. Is anyone able to tell me what happened? Is there a delay after unsuppressing contacts before they’re considered fully eligible to receive campaigns? Do previously suppressed contacts require any further action before Klaviyo treats them as truly “active” again? Is there a way to manually verify that a previously suppressed profile is now fully eligible for email campaigns?I went into my ’skipped’ emails in my campaign report and ‘resend’ each of them individually. (700). However, while I can check each of these recipients one by one and now see that they finally received and sometimes ‘opened’ the email I just resent, they still appear in

Currently, the “Placed Order” event is transferred from Shopify to Klaviyo without any delay. This means that order tags which are added a few seconds after the order is placed via a Shopify Flow are not included in the event data sent to Klaviyo. As a result, we can’t use these tags for segmentation in Klaviyo flows.Unfortunately, Klaviyo does not re-sync metrics after they’ve been recorded, so it’s not possible to retroactively include the order tags in the original Placed Order event.Has anyone found a solution for this issue or had experience with any of the following approaches? Re-fetching order data in the Klaviyo flow: Using the Shopify Admin API to fetch the latest order data (with tags) within the Klaviyo flow where the segmentation is needed. This seems complex to implement, and we’re unsure if it would work reliably. Creating a separate trigger event: Sending a custom event to Klaviyo once the order tags have been successfully added, and then using this as a trigger for s

Hi everyone,We're based in Bulgaria, and since the country is preparing to adopt the euro soon, we want to start showing both leva (лв) and euro (€) prices in our Klaviyo emails. We are with a custom CRM. We're using dynamic product blocks that pull data from our product feed (no custom code — just selecting products via the Klaviyo catalog integration).Currently, Klaviyo only lets us pick one currency (e.g., лв) per email template, and the price is pulled as a raw number without a currency symbol.What we want to do is something like this inside the dynamic block:59.99 лв (30.65 €)Is there a way to: To show both prices in the dynamic block - leva and euro.  Any advice or examples on how to achieve this would be greatly appreciated. Thanks in advance! 

Is it possible to get a pop up signup form, to just get triggered on a specific product page?Or is there anyway to easy get a back in stock signup form for a specific page?

Hi there,I would like to create a flow that is triggered by a custom property update when a user cancels their subscription.When a user cancels their subscription, I will update that custom property and I would like to send them a “Sorry to see you go” email.I think could do this with a Segment trigger or a Date property trigger, however I’m concerned that if a user cancels their subscription a second time, their Profile will not re-enter the flow.Please let me know if there is a sensible way to create a flow that will send an email every time a user cancels their subscription.Thanks in advanceJoe vB

I made a change to one of the first conditions of a flow tree and mistakenly deleted everything after it, including the emails I had setup and all the following conditions. Yikes! Is there a way to revert back? 

Hi!We’re using a Zapier python step to subscribe profiles to an additional list. Although it is adding them to the list okay, its not creating a Subscribed to List event on the profile activities as is typical for other subscribe methods in Klaviyo. For auditing purposes it would be great to see the event created but as its a default Klaviyo event I don’t believe we can create it ourselves via the API. Am I naive in thinking that this endpoint should create the event? Isn’t that part of its purpose as a subscribe call?https://developers.klaviyo.com/en/reference/bulk_subscribe_profilesLMK if I’m missing something or could achieve this in a different way. ThanksNicola

What happens if we want to resend an order confirmation email for an order that has been edited(Bigcommerce)?We had a customer email to change an order item.  We’d like to be able to resend an order confirmation showing the change.  I’m thinking that if we just resend from their Klaviyo profile messages screen, this will just resend the initial, now incorrect, order details.   Is there any way to do this and pull the variables from the now updated order?Thanks

Hi there, We sell electrical products and I want to send our customers a set up guide a few days after their purchase, so they don’t have any issues with setting up thier devices.So far I’ve learnt how to dynalically add the product name, an image of the product because that information is stored by Klaviyo.However I don’t know what to do for the button. I want to be able to show a different button url based on what the product is. This URL is a hosted PDF which they’ll download and then be able to see how to set up the device.  Let me know if there is a solution for this.
