# Email marketing beyond the blast > Anna Sophie Christensen, three-time Klaviyo Champion, on what real email personalization looks like beyond segmentation. **Author:** Nicklas Beran Bergström **Published:** April 28, 2026 **Tags:** Email Marketing, Klaviyo, Personalization, Retention, Lifecycle Marketing --- Most email marketing advice sounds roughly the same: segment your list, write better subject lines, test your send times. That's not what Anna Sophie Christensen talks about. The Head of Email Marketing & Retention at FABO — and a three-time Klaviyo Community Champion — thinks about email as an infrastructure problem. Not a creative one. The creative part is easy. The hard part is building the structure that makes relevance possible at scale. We sat down with Anna Sophie as part of our [Hello Retail Conversations](/en/conversations/) series — a collection of unscripted conversations with people shaping how ecommerce works.

## The blast email is still the norm The first thing Anna Sophie is clear about: despite years of industry talk about personalization, most brands are still sending the same email to their entire list. Not because they don't want to do better. Because the problem is harder than it looks. > "People send out to all the subscribers at once, not differentiating the message or the content. And I continuously preach that we need to differentiate — because you have your most loyal customers who have purchased from you 20 times, and you have a lead that signed up a week ago." — Anna Sophie Christensen The gap between those two people is enormous. Their relationship with the brand is completely different. Their intent is different. Their tolerance for certain types of communication is different. And yet most brands treat them identically. ![Anna Sophie Christensen at Hello Retail Conversations](/images/blog/email-marketing-beyond-the-blast-anna-sophie-christensen/anna-sophie-01.webp) ## The lifecycle frame The starting point Anna Sophie keeps returning to is lifecycle stages. Not "active vs. inactive." Not broad demographic segments. But a map of where each subscriber actually sits in their relationship with the brand. A lead who hasn't purchased yet needs reassurance and answers. A first-time buyer needs a smooth handover into the next step. A lapsed customer who bought once but never returned is an entirely different challenge. A loyal repeat buyer doesn't need a discount — they need acknowledgment. > "Some of the best performing emails we send out are emails just saying thank you. Saying, we see you. We appreciate you." — Anna Sophie Christensen That last point is worth sitting with. In a channel full of offers, promotions, and urgency, a genuine thank-you lands differently. The lifecycle frame also makes prioritization clearer. You don't need to personalize everything at once. You need to identify where the biggest gaps are in your customer journey — and fill those first. ## Zero-party data: start with one question If you're nowhere on personalization, Anna Sophie's advice is simple: start by asking one question. In the sign-up form. One question. Make it relevant to something you'll actually use later. For a jewelry brand, that might be: do you prefer silver, gold, or rose gold? For a fashion brand, it might be fit preference or style. For a food brand, it might be dietary preference. That answer gets stored as a custom property in your email platform. From that moment on, every email in that subscriber's journey can reflect it. > "Already then, you are collecting zero-party data that you can use for the overall structure on how you communicate." — Anna Sophie Christensen The key is that you're not building a survey. You're getting a micro-commitment. One answer. And you're making sure that answer actually shows up in what you send — starting from the first email. The golden rule Anna Sophie comes back to: don't collect data you're not going to use. If you ask the question, you need to build the structure that acts on it. ## In-email personalization at scale Once the data is there, the question becomes how to use it inside the emails themselves. Anna Sophie's preferred approach is show/hide logic — building a single email where different content blocks are shown or hidden based on subscriber properties. One email goes out to the entire list, but what each person sees is determined by their tag, their purchase history, their stated preference. In practice, this means the same campaign can show a man wearing jewelry to male subscribers, and a woman wearing jewelry to female subscribers. The headline is the same. The message is the same. The visual experience is completely different. > "The overall communication has the same message. But all the content inside the email, I will use the show/hide logic based off of the gender tagging that I've created inside Klaviyo — fully automated, running in the background." — Anna Sophie Christensen The power of this approach is that it scales without multiplying complexity. You're not building twenty versions of the same email. You're building one email with conditional content. And for subscribers where the data doesn't exist, you have a fallback — a version that works for everyone. ![Anna Sophie Christensen, thoughtful during the conversation](/images/blog/email-marketing-beyond-the-blast-anna-sophie-christensen/anna-sophie-03.webp) ## Timing: the dimension most people underinvest in Personalization isn't just what you say. It's when you say it. This is where Anna Sophie gets specific in ways most email marketers don't. For behavioral triggers — browse abandonment, price drops, replenishment signals — she aims to send within 30 minutes of the action. Close enough that the brand is still in working memory. The follow-up email is sent at the same time of day as the original action. > "This might be their window of shopping. Me, for example, I shop most between 11 and 12 at night. So targeting the follow-up at that moment means you're meeting them when they're actually in the mode." — Anna Sophie Christensen There's also a more tactical element: avoiding round-number send times. If every brand in a subscriber's inbox sends at 11:00 or 11:30, sending at 11:37 puts you at the top when the others have already been buried. Small detail. Real effect. ## From broadcast to dialogue One of the more interesting threads in the conversation was about what email actually is — and how rarely it's used that way. Email, by design, is a two-way medium. You write something, someone responds. That's how it works for every other kind of email. Marketing email has mostly abandoned that idea. The reply-to is often a no-reply address. The content is designed to get clicks, not start conversations. Anna Sophie argues this is a missed opportunity — not just philosophically, but practically. > "If you get the subscribers to reply to your email, you're actually using email the way it should be used from the get-go. It goes from being a transactional way of communicating to an interactional one." — Anna Sophie Christensen Her recommendation: include at least one email in every flow that asks for genuine feedback. Not a star rating. Not a NPS prompt. An actual question that invites an actual reply. The benefits are multiple: you get direct signal about what subscribers think, the data feeds back into personalization, and replies are one of the strongest deliverability signals available. Gmail and other providers interpret replies as engagement — which means your future emails are more likely to land in the primary inbox. ## Retention is a journey map, not a metric The word retention tends to get treated as a number — churn rate, repeat purchase rate, customer lifetime value. Anna Sophie talks about it differently. For her, retention is a customer journey question. Where are the gaps? Where do subscribers fall off? Where is the communication failing to move people to the next stage? > "If you have that analysis available to you, you can see where the gaps are in your customer journey — and where you should set up a new flow, or maybe adapt the settings of the flows you already have." — Anna Sophie Christensen That requires actually looking at the data — not once when you set up the flows, but continuously. This is the part she pushes back on hardest with clients: the idea that email flows are "set and forget." A paid social campaign would be optimized every week. An email flow that was built two years ago should be treated the same way. ## What Hello Retail brings to this At Hello Retail, we've been building product-level behavioral intelligence for years. What Anna Sophie is describing — lifecycle stages, behavioral triggers, timing based on individual shopping windows — is exactly the layer we can feed into. When a product has been viewed three times in a week, we know. When a replenishment window is approaching based on purchase history and product type, we know. When a price drops on something that's been sitting in an abandoned cart, we know. That signal needs to land somewhere. For most ecommerce brands, that somewhere is Klaviyo — which is one of the reasons we've invested deeply in the integration. [Product Agents](/en/product-agents/) are built on this idea: rather than manually building the flows Anna Sophie describes, the intent can be defined once and the system decides who to contact, when, and with what product. The behavioral infrastructure does the heavy lifting. The personalization Anna Sophie is working toward — emails that feel genuinely relevant, timed to individual behavior, reflecting what the shopper actually wants — is where Product Agents and lifecycle email strategy intersect. ## Final thought Anna Sophie's summary of the whole conversation landed simply: > "Recognize that your subscribers are unique individuals and that they should be treated that way. If you're just communicating the same message to everyone at all times, you're not going to win in the long run — because it's so easy to unsubscribe." — Anna Sophie Christensen That's the frame. Everything else — lifecycle stages, zero-party data, show/hide logic, send timing, behavioral triggers — is just the infrastructure that makes treating people as individuals possible at scale. **[Watch the full conversation with Anna Sophie Christensen on the Hello Retail Conversations page →](/en/conversations/email-marketing-beyond-the-blast/)** --- *This content is from the Hello Retail blog.
