Use Klaviyo for capture, AudienceTap for commerce
Most DTC brands already use Klaviyo for email and SMS marketing. They've built forms, pop-ups, and flows that capture phone numbers. But Klaviyo wasn't built for conversational SMS commerce — it excels at broadcast messaging and segmentation, not reply-to-buy transactions.
The bidirectional sync between Klaviyo and AudienceTap lets you keep using Klaviyo's capture and segmentation tools while adding text-to-buy functionality through AudienceTap. Subscribers flow between platforms automatically, with zero manual data entry.

The manual sync problem
When brands want to use separate platforms for email and SMS commerce, they typically face a painful data sync problem. They collect phone numbers through Klaviyo forms and pop-ups, then have to manually export subscriber lists and import them into their SMS commerce platform. This process is tedious, error-prone, and quickly falls out of sync.
Within days, the two platforms have different subscriber counts, different opt-in statuses, and different engagement data. A customer who opted out in one system is still subscribed in the other. Purchase data from text-to-buy transactions doesn't flow back to Klaviyo, so email segmentation based on SMS behavior is impossible. The brand ends up managing two separate subscriber lists that should be unified.
For brands that want best-of-breed tools — Klaviyo for email automation and forms, AudienceTap for text-to-buy — the lack of seamless integration forces them to choose one platform or live with constant data headaches.
Bidirectional sync between Klaviyo and AudienceTap
AudienceTap's Klaviyo integration syncs subscriber data in both directions automatically. When a customer submits their phone number through a Klaviyo pop-up, embedded form, or checkout opt-in, that subscriber is instantly added to AudienceTap. When a subscriber joins your list through AudienceTap (via a QR code, keyword, Instagram automation, or referral), their data flows back to Klaviyo.
Purchase behavior from text-to-buy transactions syncs to Klaviyo as well, so you can segment email campaigns based on SMS engagement. A customer who bought from a text drop can be targeted with a follow-up email. A customer who hasn't responded to recent text offers can be re-engaged via email. The two channels work together, not in silos.
This setup gives you the best of both platforms: Klaviyo's powerful forms, flows, and email automation, combined with AudienceTap's conversational text-to-buy engine. Your brand doesn't have to choose — you get both.

| Purchase data flow | SMS purchases don't appear in Klaviyo | Text-to-buy orders sync to Klaviyo for segmentation |
| Opt-out consistency | Customer opts out in one platform, still subscribed in the other | Opt-outs sync across both platforms |
| Cross-channel segmentation | Impossible — data lives in separate systems | Full cross-channel segmentation — SMS behavior informs email, vice versa |
