Keeping up with ecommerce technology can feel like another full-time job. For Shopify and WooCommerce store owners, the useful question is simple: which changes deserve your attention, and how could they help your business?
Klaviyo’s September announcements offer plenty to consider. But before adding another tool to your marketing, it pays to understand the opportunity and check whether your existing setup is ready.
As a certified Klaviyo partner, my focus is on connecting platform developments to practical improvements: more relevant emails, better customer journeys and a clearer plan for encouraging repeat purchases.
What has Klaviyo announced?
On 9 September 2026, Klaviyo announced expanded access through external AI tools, new data analysis capabilities and further developments in personalisation.
Klaviyo Headless allows supported AI tools to work directly with Klaviyo through its MCP connection. Composer’s announced capabilities include scheduled tasks for recurring analysis and reusable instructions for brand guidelines or established marketing processes.
The new Personalisation layer brings together decisions about audiences, content, timing and channels. Both Personalisation and the new SQL analysis capabilities were described as being in Preview in the announcement.
Availability may vary, so check which features your account can access before planning an implementation.
1 – Start with the customer data behind your marketing
My recommendation is to begin with a review of the information reaching Klaviyo from your store.
- Are orders being recorded correctly?
- Do your customer profiles contain the details you need for useful targeting?
- Are your flows responding to the right events?
For example, a post-purchase email recommending an accessory needs to account for what the customer has already bought. Otherwise, even a polished copy can produce an irrelevant message.
For Shopify and WooCommerce businesses, this means looking beyond whether the integration is connected. Test the events, properties and product information your actual campaigns and flows depend on. The available data can vary with your platform, configuration and additional apps.
Reliable data gives you a stronger basis for both manual decisions and AI-assisted work.
2 – Use faster analysis to ask better questions
A report is useful when it helps you decide what to do next.
Instead of asking only how much revenue email generated last month, I would also look at:
- Where the customer journey needs attention.
- Are welcome subscribers progressing towards a first purchase?
- Which products attract repeat buyers?
- Has a previously successful flow started losing effectiveness?
A recurring review can help keep these questions on the agenda. The important step is interpreting the findings in context.
A drop in sales could relate to stock availability, a change in promotions, seasonality or a technical issue. Each explanation calls for a different response. Faster analysis is valuable when it leads to a well-informed action.
3 – Make personalisation useful to the customer
Personalisation should help someone make a decision.
- A first-time visitor may need reassurance about delivery, quality or choosing the right product.
- An existing customer may be more interested in compatible accessories, replenishment or a relevant new arrival.
Start with a few clear customer groups and a reason for treating them differently. You could distinguish first-time customers from repeat buyers, or tailor follow-up content to the product category purchased.
For example, someone buying a specialist tool might benefit from guidance on using and maintaining it before receiving another sales message. Someone buying clothing might appreciate care advice and suggestions that complement their purchase.
These are examples of the strategy I would establish before testing more advanced personalisation. Decide what would be helpful, confirm the data supports it, then measure the response.
4 – Review the flows you already have
Before investing time in new capabilities, check your existing automations.
A welcome flow, abandoned checkout sequence or post-purchase journey can remain active for months while the business around it changes. Products sell out, delivery policies change and introductory offers evolve.
- Review the timing, links, recommendations and eligibility rules.
- Check whether customers can receive overlapping messages or an offer intended for a different stage of their journey.
- Prioritise the issue most likely to affect the customer experience or commercial performance.
One well-chosen improvement can be more useful than launching several new features at once.
5 – Build a monthly improvement plan
For an ecommerce business, I recommend treating Klaviyo as an ongoing part of the customer experience.
A practical monthly plan should connect performance reviews with changes you can evaluate. That might mean improving one flow, testing a campaign approach, refining an audience or fixing a gap in tracking.
Agree the purpose of each change before making it. If you are trying to encourage second purchases, assess progress towards that goal rather than relying solely on opens or clicks.
Keep a record of what changed and what you learned. Over time, this creates a more informed marketing programme, with decisions based on your customers and your store.
Klaviyo’s latest developments give businesses more options. The next step is choosing where those options fit into a clear, manageable strategy.
