Klaviyo Launches Social Engagement Marketing: How To Transform Your Engagement Into Owned Revenue

Your Instagram isn’t broken, the platform is just not optimised to convert. Weeks to months are spent in advance curating the perfect Instagram aesthetic. Your reels are landing, impressions continue to grow, the comments are rolling in, and your latest drop has followers tagging friends —  but the revenue driving question is: how many of those people are actually on your email or SMS list?

If the answer is "not many," you're not alone — and Klaviyo has just built the infrastructure to change that.

In August 2025, Klaviyo acquired Gatsby, a social automation platform that captures social signals like DMs, tags, mentions, and follows. Rather than keeping this as a bolt-on integration, Klaviyo has since rebuilt these capabilities natively into its platform — launching what it calls Klaviyo Social Marketing.

The first feature, Social Auto-replies, is free for every Klaviyo customer and available now. This tool automatically responds to Instagram comments and DMs, capturing consented email and phone numbers from Instagram users directly into Klaviyo profiles — no third-party tool, no manual export, no separate dashboard.

A broader suite of features is currently in Early Access, with more on the way.

For brands in fashion, lifestyle, and beauty, social media channels have always been the first point of discovery in the customer experience journey. You, as a brand, invest time and budget into building a social presence, from content creation to paid advertising, and influencer partnerships. The brand engagement earned as a result of these online strategies is a genuine signal of audience interest and intent.

Until now, those un-trackable yet incredibly pivotal signals have been unable to be utilised. Followers remained simply as followers. Social platforms owned organic engagement. You owned the email list. And the two rarely spoke to each other.

Now, Klaviyo Social Marketing closes that gap. Strategically comment, DM, tag, and mention can now become a data point on a real customer profile - one that sits alongside your flows, segments, and purchase history in a single location.

Social Auto-Replies (Free & Available Now)

Brands set a keyword — e.g., "access" or "drop" — and when an Instagram follower comments or DMs that word, Klaviyo automatically replies and guides the user through an opt-in to join your email, SMS, or WhatsApp list. Consent is captured within the exchange itself, meaning every contact acquired is one you can legally market to. No deliberating on user rights required.

This is particularly important for:

• Brand Campaign Launches - prompt followers to DM or comment a keyword to gain access to your next product drop or sale campaign. 
• Always-On Sign Up Offers - run an evergreen opt-in (such as a 10% discount code) directly from your Instagram bio or channel group chat.
• Organic Giveaways - collection large volumes of high-intent engagers through high-engagement promotions.
• VIP Community Building - give back to your highly engaged organic community, identifying people following you and segment them accordingly to foster brand loyalty.

An early access study by Klaviyo saw one e-commerce brand grow their SMS list at a cost of $3.39 per acquisition - a substantial result considering the existing investment into this channel, which previously would have failed to translate the same volume of quality leads.

Engagement Events Insights (Early Access)

Once a follower opts in, Klaviyo begins logging their social interactions as events on their profile. A comment on your launch reel, a story mention, a DM — all of it feeds into the same event feed you already use for purchase behaviour and email engagement.

From there, the possibilities open up quickly. Build a segment of customers who engaged with your latest campaign reel but haven't yet purchased, and trigger a targeted flow. Create an automated ambassador programme using follower count and mention events. Identify your top advocates at a glance — not just by what they've bought, but by how loudly they show up for your brand online.

Social Content Library (Early Access)

Every tagged post, story mention, and reel is collected in one place. Your team can identify trends, spot emerging creators, and make smarter decisions about what content is actually driving connection — without toggling between platforms.

One Instagram Profile, Multiple Regional Connections (Early Access)

For brands operating across multiple markets, Klaviyo now supports connecting one global Instagram account to multiple regional Klaviyo accounts — ensuring opt-ins are captured and allocated to the right list, in the right region.

This is a meaningful shift in how owned audience growth operates, and the brands that move early will have a structural advantage, shaping the new organic landscape as we know it.

For luxury and premium brands, the opportunity is real — but so is the responsibility to get the tone right. Adopting these tools without consideration risks undermining the very voice that earned your audience's loyalty in the first place.

Here are some things worth considering before launching into action:

Social intent is high-intent. Someone who comments on your product launch reel is not a cold prospect. They've already found you, engaged with your content, and signaled their interest. Converting that person into a subscriber costs a fraction of what paid new acquisition does — and they tend to behave more like loyal customers than cold traffic.

Your list-building strategy needs to evolve. Traditional website forms and pop-ups will remain part of the mix, but the growth ceiling on those channels is slow and getting lower as acquisition costs rise.  Social Auto-replies open a new, lower-cost channel that works alongside your existing content investment.

Data hygiene and consent matter more than ever. Because Klaviyo captures opt-in consent within the Instagram exchange itself, the contacts you collect are compliant — but it's still worth thinking about how you segment and communicate with this new cohort. Someone who opted in through a product drop keyword has a different relationship with your brand than a long-term customer. Treat them accordingly.

This is just the beginning. Klaviyo has indicated that Social Marketing will expand to include additional platforms beyond Instagram, deeper profile enrichment from social data, and the ability to trigger fully personalised journeys from DMs, tags, and user-generated content. The foundation being built now is what will power those capabilities later.

The lines between social, email, and commerce have been blurring for some time. What Klaviyo has done is give brands the infrastructure to actually act on that reality — without adding new tools, new contracts, or new complexity.

The brands that will win in this environment are the ones that treat every engaged follower as a potential owned contact — and build the systems to capture that relationship before it disappears into the feed.
