In 2023, Soundliving decided to integrate SMS as an additional leg in their marketing mix. The goal was clear: to get closer to customers and increase traffic to the website.
The effect was clear from the very first campaign - traffic increased and conversion rates followed.
About Soundliving
Soundliving is a Danish audio and lifestyle brand that since 2017 has specialised in headphones and speakers where design, quality and price go hand in hand. The vision is simple: to sell stylish and functional products at prices that everyone can afford.
SMS now plays a central role in Soundliving's marketing mix and customer journey, and is used for campaigns, automated flows and customer service. And the effect can be felt directly on both traffic and sales every time they press "send".
Challenge: Closer customer dialogue and more traffic
Soundliving wanted to get closer to their customers and drive more traffic to the webshop. Emails were already an important part of the marketing mix, but they were missing a channel where they could have a more direct and quick dialogue with customers.
So in 2023, they decided to test SMS and the effect was clear from the very first campaign. Their traffic increased shortly after the broadcast and conversion rates followed.
"We had heard really positive things about SMS and wanted to test the channel ourselves.
Today, we can clearly see when an SMS is sent - traffic increases and orders start coming in almost immediately."
- Sebastian Hansen, Co-Founder of Soundliving
However, the first step in the SMS adventure was to identify how the channel could integrate naturally with their existing marketing setup. They quickly solved this and today they have the right setup where inMobile, Klaviyo and Shopify are integrated and share data. This ensures that they can work with highly targeted SMS segments in both campaigns and flows.
Solution: User-friendly SMS gateway
The choice of SMS partner fell naturally on inMobile. Soundliving wanted an SMS solution that was easy to use, stable in operation and competitive on price - and with inMobile's SMS gateway they got just that.
The setup was simple and the high level of usability made it easy to get started quickly. At the same time, the price was significantly lower than the alternatives they had researched - an important factor when sending many messages and working with frequent campaigns.
Support is also an important part of the reason why Soundliving continues to use inMobile for SMS.
"We use inMobile because it's easy to use and affordable. And we have also enjoyed their great support."
- Sebastian Hansen, Co-Founder of Soundliving
With inMobile, Soundliving can now automate their flows, target campaigns and draw on customer data to send accurate and relevant messages. Their lost basket flow in particular performs well and is clear proof of how effective SMS can be when used correctly.
Promotions and offers
Campaigns are an integral part of Soundliving's SMS strategy. They typically send an SMS campaign a couple of times a month, for example when new products, collections or special offers are launched. It's a fast and effective way to drive traffic to your webshop, and the effect can be seen almost immediately in both visitor numbers and conversions.
SMS campaigns are used especially during big sales periods such as Black Friday, when the frequency is turned up a bit. However, it is a regular part of the content plan all year round.
Automatic flows
In addition to their campaigns, Soundliving also works with automatic SMS flows. This ensures that they reach customers with relevant communication at the right points in the customer journey - automatically.
Lost-curve flow provides ROAS 360 x
A popular SMS flow that Soundliving has set up is their lost basket flow. Here they automatically send an SMS to website visitors who have added items to their basket but not completed the purchase.
The flow is set up via Klaviyo webhooks connected directly to inMobile. This way, they can build flows with both SMS and email, while inMobile ensures fast and stable delivery of SMS messages.
Again, the results speak for themselves: During September 2025, 153 automated SMSes were sent through the flow with the following results:
- Click-through rate: 21.57%.
- Cancellation rate: 0%.
- Revenue: 15,920 kr.
- ROAS: 360 x
And that's without any manual labour.
Customer service and dialogue
In addition to campaigns and flows, Soundliving also uses SMS in their daily customer dialogue.
They particularly use inMobile's Conversations feature for returns and complaints, where customers receive an SMS with status or updates directly from the returns portal. The customer can also reply back to the messages if there are any questions or need for further dialogue.
This provides fast and personalised communication that customers appreciate.
Result: Measurable impact on sales and customer journey
For Soundliving, SMS has proven its value as both a sales and service channel. SMS allows them to communicate directly with customers - and it shows on the bottom line.
Each broadcast creates a significant boost in web traffic and conversions - and customers respond quickly. This applies both during major campaign periods and on a day-to-day basis, where SMS is used as a regular part of the customer journey.
"SMS has become an important part of our marketing strategy. It gives us a direct line to customers that we don't get in the same way through other channels."
- Sebastian Hansen, Co-Founder of Soundliving
Black Friday SMS strategy: 11x ROAS on 4 campaigns
During Black Week 2024, Soundliving used SMS marketing as an active part of their strategy.
The SMS strategy was simple but effective: four targeted SMS campaigns sent first to their VIP segment and then to previous customers who had not shopped during Black Week 2024.
The first campaign was sent to their VIP list and gave early access to selected offers. Looking at the ROAS of the campaign, it performed extremely well. VIP segments generally respond positively to early access campaigns as it creates a feeling of being part of something exclusive.
"Our Black Week campaigns performed really well. We saw a significant boost in both traffic and conversions - and we will definitely repeat the success with similar campaigns this year."
- Sebastian Hansen, Co-Founder of Soundliving
Subsequent campaigns were rolled out more widely as the sale started, with a focus on strong offers and a 'surprise gift' for all shoppers.
With a total investment of around DKK 24,000 in SMS, Soundliving generated a turnover of DKK 276,000 across 509 orders. This corresponds to an average ROAS of 11.4 - or 1,140%.
The experience from Black Week 2024 has given Soundliving a clear understanding of how strongly SMS performs in periods of high competition.
The combination of segmentation, VIP lists, special offers and early activation has proven to be effective, and they plan to repeat and scale a similar SMS campaign for Black Week 2025.
The future of SMS: Multiple flows and new markets
At Soundliving, SMS is now an integral and valuable part of the business - both as a marketing channel and in customer dialogue. Experiences from campaigns and automated flows have shown how effective the channel is at driving results, and the next step is to expand its use further.
The company is working on setting up more automated flows to make SMS an active part of even more steps in the customer journey. Soundliving also has its eyes on new markets where SMS must be incorporated as a natural part of the strategy.
"SMS has become an important part of our business - both as a traffic source and in the dialogue with our customers. We can see that it works and we still have a lot more we want to try."
- Sebastian Hansen, Co-Founder of Soundliving
At inMobile, we look forward to continuing the collaboration and helping Soundliving develop their SMS setup so that it continues to create measurable results - also across new markets.
