Klaviyo agency: email marketing that brings customers back

A Klaviyo agency looks after the channel most shops take seriously last, and the one that often earns the most in the end: email. Your email list belongs to you. You pay no cost per click, you reach people who have already bought or signed up, and you build recurring revenue that does not depend on an algorithm. As an email marketing agency in Switzerland, we set up Klaviyo so this channel runs predictably, and we run it for you on an ongoing basis if you wish.

Why a Klaviyo agency starts with the most profitable channel in your shop

An online shop wins new customers through search and ads. Both are expensive, and the first purchase rarely covers the cost of acquisition. The profit comes from the second, third and fourth purchase. That is where email does its work: it brings buyers back without you paying for the contact again. In the shops we look after, email often accounts for a quarter to a third of revenue once the setup is done properly. That shows why email automation for online shops belongs to the foundation on which shop, SEO and ads stand together.

What a Klaviyo agency makes of the link between Klaviyo and Shopify

Klaviyo is built for Shopify. The integration transfers customer data, orders, carts, viewed products and the catalogue in real time. This opens up possibilities a classic newsletter tool does not have: product recommendations based on real purchase history, triggers on events in the shop, and segments that update themselves every day. The technical connection takes an hour. The work begins afterwards: which events trigger an email, which data is missing in the shop, how do consents reach Klaviyo cleanly. With Shopify Plus, checkout extensions and multiple markets come into play, and our Shopify Plus agency is the place to go for that.

Klaviyo flows: the automations a Klaviyo agency sets up first

Klaviyo flows are automated email series that respond to behaviour. Once set up, they run without any campaign planning. Six flows carry the largest share of automated revenue in almost every shop:

• Welcome series: three to five emails after sign-up. They introduce the brand and lead to the first purchase.
• Abandoned cart email: a reminder one to two hours after the cart is abandoned, a second one after a day. With the products from the cart and a direct link to checkout.
• Browse abandonment: for visitors who viewed a product but did not add it to the cart. Used sparingly.
• Post-purchase: thanks, shipping information, usage tips, and later a request for a review. This series decides whether a first-time buyer becomes a regular customer.
• Winback: customers with no purchase for 90, 120 or 180 days receive a targeted message.
• Replenishment for consumable products: coffee, cosmetics or snus run out after a known period. A reminder shortly before that replaces the impulse a competitor would otherwise provide.

The Klaviyo setup for these flows takes a few weeks, because every series needs copy, design and logic. After that, they run for months.

Campaigns and segmentation with a Klaviyo agency

Campaigns are the planned sends: new products, promotions, seasonal topics. The most common mistake is sending every campaign to the whole list. That drives up unsubscribes. Klaviyo segmentation solves this: VIP customers with a high order value get early access instead of discounts, inactive contacts get fewer emails and a clear reactivation offer, and customers with a particular product interest get content on that topic. We usually build eight to twelve segments from the Shopify data and define how often each segment is contacted. As a newsletter agency, we take over the day-to-day operation if you wish: editorial calendar, copy, design, sending and reporting.

Deliverability and legal requirements: what a Klaviyo agency in Switzerland and the EU pays attention to

The best email is worthless if it lands in the spam folder. Deliverability depends on authentication (SPF, DKIM and DMARC on a dedicated sending domain), on the quality of the list and on sending behaviour. A new domain is warmed up step by step. Legally, Switzerland applies the revised Data Protection Act and the Unfair Competition Act (UWG), while Germany and Austria apply the GDPR and their national competition rules. In practice, this means:

• Double opt-in for every sign-up, with documented confirmation in Klaviyo.
• An unsubscribe link in every email that works with a single click.
• A privacy policy that names Klaviyo as a service provider and covers the data transfer.
• Separate consent for Klaviyo SMS, because SMS is treated more strictly than email.

We check existing lists before a migration so that no addresses without valid consent continue to receive emails.

How a Klaviyo agency connects email with SEO and ads

Visitors from search and ads first need to join the list. That is why sign-up forms and pop-ups with sensible timing are part of the setup. In turn, a good list takes pressure off the advertising budget: anyone who returns through email does not need to be won again through Google Ads. Segments from Klaviyo can also be exported as audiences to Meta and Google. Because shop, SEO, ads and email all come from one team here, we coordinate these handovers directly.

Reporting: how you measure the success of your Klaviyo agency

Since Apple introduced its privacy features, open rates have only limited meaning. We therefore report on metrics tied to your revenue: revenue per recipient, revenue per flow and campaign, email's share of total revenue, repeat purchase rate by segment and unsubscribe rate. We configure attribution so it matches your Shopify reporting. You can read more about metrics and methods in our marketing guide.

Klaviyo agency for industries without ads: CBD and nicotine

For CBD, hemp products, snus and nicotine, Google and Meta allow few or no ads. These shops have two channels they control themselves: search and email. We look after several brands in these sectors, including Green Passion, Heimat, Shinygram and Snus-Shop, and we see there that email is not a supplement but the main channel. The content has to stay factual and must not make any claims about effects. Our page on SEO for CBD shops describes how we build search for this industry.

Services of our Klaviyo agency and what the costs depend on

Depending on where your shop stands, we take on individual building blocks or the entire channel:

• Klaviyo setup with Shopify integration, sending domain, consents and forms
• Migration from Mailchimp, Brevo, ActiveCampaign or other tools, including list clean-up
• Design templates in your brand's style, tested on the common email clients
• Building and writing the flows, matched to your range and purchase cycle
• Campaign operation with editorial calendar, segmentation and sending
• A/B tests on subject lines, send times, content and offers
• Klaviyo SMS as a supplement for shipping status and time-critical promotions

Klaviyo costs have two parts: the licence, which Klaviyo bills by active profiles and SMS sent, and the effort for setup and operation. The latter depends on how many flows and segments you need, whether a migration with data clean-up is involved, whether templates are redesigned, and whether ongoing operation sits with your team or with us. In the initial consultation, we look at your shop and your list and give you an assessment of which building blocks make sense first.
