Hello,I had previously verified my domain or at least I thought I did. I had Ionos customer service manually add 4 NS email DNS records. I have just had a theme transfer done and I'm not sure why but when I went to check I was not seeing my domain verified. Chat GPT had me deleted these NS records which I believe was a mistake as I started the verification process again and need to add them again to my records but I don't know if this is also causing an issueIf you have anything else in IONOS with host email (like CNAME email, A email, TXT email) delete it.With NS delegation, email.* is “owned” by Klaviyo—other email records at IONOS can conflict or be ignoredAny help would be greatly appreciated as I don't not have a paid account . Thanks,Zack 

Hi all,I had a brand a few years ago which was closed. I had saved the Klaviyo contacts and have uploaded them to my new Klaviyo account with the intention of re connecting with them.I am getting in touch as, although the brand is new and a different name, it’s the same product and so they have interest.I would like to know the best way of getting in touch with these contacts. Im thinking of some kind of re engagament email with them giving permission for future mails.I have about 30,000 contacts.Also, My account is free right now and I realise I will need a better plan, but is there a point until I know if I can re engage and then, how many subscribers I have left after this?Thanks

Hi everyone,We’re running 16 separate Klaviyo accounts (one per country/store). Our workflow is: build emails in NL first, then duplicate across accounts and manually replace blocks + translate all copy to the local language. As you can imagine, this doesn’t scale.Has anyone dealt with a similar multi-account setup? What’s the best way to automate this (e.g., via Klaviyo APIs, exporting/importing templates, or a translation workflow? Any proven approach, tools, or best practices would be hugely appreciated.ThanksJustin

Hey everyone, I’m Stefan Milicevic, Strategy Director at Underground Ecom. Since we are officially in the new year, I wanted to share some of what I have reflected on and am most looking forward to in the coming months.2025 was the year of experimentation. Brands tested AI, but few built sustainable systems around it. What stood out most was how inconsistent personalization still feels, even with advanced marketing technology. We saw some really interesting results when brands paired automation with human strategy.When I think about ecommerce trends 2026, one stands out: AI-driven personalized automation. I’m most excited about how AI will transform Klaviyo marketing trends, allowing brands to adapt messaging in real time.Imagine this: A checkout-abandonment flow that does not j

Here's a pattern I see across most subscription brands: teams pour time and budget into acquisition and winback campaigns, while their highest-LTV segment—active subscribers—quietly sits in the background with minimal attention.These customers are already convinced. They're already paying you. They're already showing signs of long-term loyalty. But they're also the group most likely to churn silently if you're not staying present in their experience.Active subscriber marketing isn't about bombarding people with more email. It's about the right, well-timed touchpoints that reinforce value, build habits, and keep subscribers engaged far before churn becomes visible in your metrics.If you're looking to increase LTV this year, here's where I'd focus.

We’re using a Klaviyo signup form to collect applications and the flow is triggered when someone submits that form and joins the list. After submission, we send an internal notification so our team can review the application details. From there, we only want applicants who are approved by our team to continue through the rest of the flow, while unapproved applicants should not receive any follow-up emails.I wanted to ask if there’s a recommended or best practice way to build this kind of approval based setup in Klaviyo, where progression through the flow depends on a manual approval step.

Has anyone created an archive on their site of past newsletters to allow users to browse older content? Anton

After talking to my clients we decided that registering to text Texas is not worth it for their business at the moment (not enough business coming from Texas to make it worth the expense of registering). What are the best ways to exclude Texas from SMS? This is what I’m thinking:Adding a filter to my SMS flows to prevent those with their State Profile Property set as “Texas” from entering Create a segment for SMS subscribers excluding those based in Texas  Profile Property → State → TexasIs there anything else I should be thinking of? An additional filter to ensure no SMS slips through?  

Has anyone come across this platform and is using it? It sounds great / sounds like tech that Klaviyo should have built in (!) but it’s expensive and want to see if anyone is using it and can vouch for it?

Hi everyone,I’m running into an issue with the Added to Cart metric for a client on Shopify who offers shipping insurance.I was able to hide the shipping insurance from the checkout flow, but since the Added to Cart flow triggers per event, it’s been tricky to manage. I added a filter so the flow doesn’t trigger when the only item in the cart is shipping insurance. However, most of the emails going out still show only the shipping insurance, since it’s often the first product that triggered the event.I searched the community but didn’t find anyone reporting a similar issue. Has anyone else dealt with this on Shopify? I’d love to hear any workarounds or best practices to make sure that emails aren’t showing just the shipping insurance.Thanks in advance!

We recently completed a rebrand. Our original domain had a strong email reputation, but the new domain is still building its deliverability and currently has a poor reputation. If we temporarily switch back to the old domain for Black Friday and Cyber Monday, will email providers treat it as the same trusted sender we had before, or will returning to that domain trigger a reputation reset and require another warmup process? We want to avoid any risk of landing in spam during the next two weeks of holiday sales.After the season, we plan to go back to the new domain and follow a full warmup strategy to rebuild deliverability. For now, we just need to understand whether using the old domain again would restore reliable inbox placement for our holiday sends.

Hello,Im getting high bounced rate with my abandoned checkout flow and it’s hitting my deliverability.On checking all of it are spam emails. What’s the best way to filter this emails so klaviyo won’t send emails to bots?

Klaviyo has been creating a lot of "engaged non openers" segments from my campaigns. What should I do with these?

Hi ,I need help setting up a flow that prevents sending a reminder email if someone places an order for the same product they saved earlier.Here’s my setup: Trigger metric: Product Saved Event properties example: { "sku_last_part": "5932", "product_name": "bird-8788491", "price": 12, "product_sku": "1105-5932", "pt_sub_id": "6" }   Placed Order event example: { "order_total": 153.9, "sku_last_part": "5932", "product_names": ["bird-8788491"], "currency": "USD", "items": [ { "price": 12, "quantity": 12, "product_name": "bird-8788491", "product_sku": "1105-5932" } ], "order_id": "1", "product_skus": ["1105-5932"], "$value": 153.9 }   Goal:If a customer saves a product (Product Saved event) and does

We’re on Microsoft Dynamics 365 and currently manage another CRM via Zapier to connect with Klaviyo (which is getting a bit expensive).Has anyone compared n8n, Zapier, and Make.com for integrating Dynamics 365 with Klaviyo? I’d love to hear your experiences.Key workflows we need: CRM → Klaviyo: Contact update, contact deletion, new profile Klaviyo → CRM: Bounce events, unsubscribed events

HiI’m trying to clean my list to keep my costs down and I realise I’ve probably got a lot of inactive profiles. I have created this segment to potentially supress, but are there any red flags in here or anything that I’ve missed ? Am I safe to supress this whole segment?this is my definition: email is set to textcreated at least 180 days agoopened email zero times over all timeclicked email zero times over all timeactive on site zero times over all timeviewed product zero times over all timecheckout starter zero times over all timeplaced order zero times over all timeAny better recommendations welcome. I have set up a sunset flow and I will try one last attempt to move people out of this segment but just wanted to make sure I’m doing the right thing.

Hey everyone,Problem with Back-in-Stock emailsSo I ran into this annoying problem with Back-in-Stock emails - customers subscribe to out-of-stock products, get the confirmation email, but there's no way to show them alternatives.The thing is, you can't modify Klaviyo events after they're sent. PrestaShop integration fires the event and that's it - it's locked. Can't touch it. And I really didn't want to start messing with official integration code. The workaround I came up with:Instead of trying to modify the event (impossible), I'm using Klaviyo profiles as temporary storage through Flow webhooks. Basically:Flow webhook fires before the email → my service grabs similar products from PrestaShop → stores them temporarily in the user's profile Email template reads from the profile → renders products directly from Klaviyo Catalog Another
