Hi ​@danielmartinhq! Thanks for posting – this is a really interesting discussion that has even caused me to think a lot more about how I leverage TikTok engagement within Klaviyo. Currently my company does not directly use TikTok within Klaviyo, but we do frequently talk about email and SMS in TikTok videos and TikTok lives. Syncing leads from TikTok ads into Klaviyo would get pretty tricky because you have to receive content prior to sending them emails/SMS and I am not sure if there is a legal way to gather leads like that from TikTok. Making sure that Klaviyo sign-ups are super easy to find on your site (and are optimized for mobile!!!) will better convert people coming from TikTok. 

My company has found a lot of success with packing videos, so every once in a while we will make a gif of a TikTok and use that in emails. We’ve also taken advantage of universal assets in emails to make sure that TikTok is always linked in the email footer. Would definitely love to hear other people’s ideas!

Great question, ​@danielmartinhq - I’m seeing the same trend with TikTok driving solid top-of-funnel traffic, and there are a few ways I have been integrating it with Klaviyo:

Lead Syncing from TikTok Ads

We sync leads from TikTok Lead Ads directly into Klaviyo using Zapier via a TikTok > Google Sheets > Zapier flow. It works well, but list quality can vary. Warm-up sequences are key, I run a dedicated TikTok Welcome Flow that assumes low brand familiarity and uses social proof/UGC early on.

TikTok-Style Content in Emails

I’ve embedded TikTok-style UGC in both campaigns and flows. These drive higher engagement, especially in abandoned cart and post-purchase emails. Think: “Here’s how I used it” videos or real-time testimonials.

Segmenting TikTok Leads

We tag TikTok leads on entry so we can track their performance separately in terms of open, click, and conversion rates. This helps optimize both ad targeting and email content over time.

I’m still experimenting, but the biggest win so far has been repurposing TikTok creative inside Klaviyo, the authenticity plays great in inboxes.

@zacfromson2025 Zapier workflow sounds super solid. We’ve done something similar but didn’t tag users by source, and now I see how useful that would be for optimization. And you’re right — TikTok-style UGC works really well in abandoned cart flows, especially when it’s raw or funny.

Thanks a lot for the insights @rqcha2025 — super relatable stuff. We’ve had similar challenges trying to sync leads directly from TikTok. Between legal grey areas and the platform’s limitations, we’ve kind of shifted our focus too — instead of pulling leads straight from TikTok, we now direct viewers to a lightweight landing page first and collect emails there.

What’s been working surprisingly well is using TikTok-style clips (short, raw, sometimes even borderline edgy) and then embedding them into the email flow later. We actually started testing this with a mini project that pulls in traffic from a more unfiltered TikTok niche. Not sure if you’ve seen these before, but something like this kind of content app — not traditional brand-safe stuff, but it’s helping us reach audiences we weren’t connecting with before.

Also +1 on your point about mobile-friendly signup forms. If there’s even a second of lag or confusion, TikTok users just bounce.
