# Attentive Mobile + Klaviyo integration > Sync your SMS and email channels so campaigns stay coordinated, subscribers stay current, and your team isn't doing manual list work. **Canonical page:** https://tray.ai/connectors/attentive-mobile-klaviyo-integrations/ **Attentive Mobile connector:** https://tray.ai/connectors/attentive-mobile-integrations/ **Attentive Mobile documentation:** https://tray.ai/documentation/connectors/service/attentive-mobile **Klaviyo connector:** https://tray.ai/connectors/klaviyo-integrations/ **Klaviyo documentation:** https://tray.ai/documentation/connectors/service/klaviyo ## Overview Attentive Mobile and Klaviyo are two of the strongest customer engagement platforms available to ecommerce and retail brands — one built for SMS, the other for email. When integrated, they let marketing teams run genuinely omnichannel campaigns where subscriber behavior, preferences, and purchase history flow between both platforms. Instead of managing two disconnected audiences, brands can build unified customer profiles and trigger the right message, on the right channel, at the right moment. Email and SMS are stronger together than apart, yet most brands run them in separate silos. A customer who abandons their cart may respond better to a text, while a loyalty program update belongs in the inbox — but without a live data bridge between Attentive and Klaviyo, your team can't act on those insights automatically. Integrating through tray.ai eliminates manual list exports, cuts data lag, and keeps segment membership, opt-in status, purchase events, and campaign engagement data synchronized in real time. Marketing teams get a full view of every subscriber, which means smarter suppression, tighter segmentation, and revenue attribution across both channels. No custom code required. ## Use cases ### Cross-Channel Subscriber Sync When a customer opts into SMS through Attentive, their profile and consent data gets pushed to Klaviyo automatically so they can be enrolled in the right email flows right away. New email subscribers captured in Klaviyo can be flagged for SMS acquisition campaigns in Attentive. This bidirectional sync means no subscriber falls through the cracks regardless of which channel they came in through. - Eliminate manual CSV exports and list uploads between platforms - Cut time-to-first-message for new subscribers from hours to seconds - Maintain accurate consent and opt-in status across both channels ### Abandoned Cart SMS and Email Orchestration When a shopper abandons their cart, tray.ai can coordinate a multi-step recovery sequence that triggers an SMS via Attentive and a follow-up email via Klaviyo based on engagement. If the customer doesn't open the email within a defined window, an automated SMS nudge fires through Attentive — and once a purchase is completed, both platforms are updated to suppress further recovery messages right away. - Recover more revenue with coordinated, channel-aware abandonment sequences - Prevent message fatigue by suppressing converted customers across both platforms - Customize timing logic between SMS and email without manual oversight ### Unified Segment Mirroring High-value customer segments, VIP lists, and churn-risk cohorts built in Klaviyo can be automatically mirrored into Attentive as custom segments for targeted SMS campaigns. When your email team updates a segment based on RFM scoring or behavioral data, your SMS team is working from the same audience definition without re-uploading lists manually. - Keep SMS and email audiences aligned at all times - Cut duplicated segmentation work across marketing operations - Power personalized SMS campaigns with Klaviyo's behavioral data ### Post-Purchase Flow Coordination After a customer completes a purchase, tray.ai routes the order event to both Attentive and Klaviyo at the same time, triggering a transactional SMS confirmation and a branded email receipt or upsell sequence. Subsequent post-purchase milestones — shipping updates, review requests, replenishment reminders — can be split across channels based on customer communication preferences stored in either platform. - Deliver consistent post-purchase experiences across SMS and email - Cut operational overhead by automating order event routing - Improve customer satisfaction with timely, channel-appropriate updates ### Opt-Out and Suppression Management When a subscriber unsubscribes from SMS in Attentive or marks an email as spam in Klaviyo, that opt-out has to be honored across every channel to stay compliant and protect sender reputation. tray.ai automates suppression event propagation so a STOP reply in Attentive immediately updates Klaviyo's suppression list, and vice versa, without any manual intervention. - Maintain CAN-SPAM and TCPA compliance across both platforms automatically - Protect sender reputation by preventing messages to opted-out contacts - Cut manual suppression list management for marketing ops teams ### Winback Campaign Coordination Lapsed customers identified through Klaviyo's predictive analytics can be automatically passed to Attentive to trigger a targeted SMS winback sequence for subscribers more likely to re-engage via text. Engagement signals from Attentive — link clicks and conversions — feed back into Klaviyo to update the customer's engagement score and pull them out of winback flows once they're re-activated. - Re-engage dormant customers through their preferred channel - Use Klaviyo's predictive data to sharpen Attentive targeting - Automatically close the loop on winback conversions across both systems ### Event-Triggered Personalization at Scale Behavioral events tracked in Klaviyo — product views, wishlist additions, loyalty tier changes — can trigger personalized SMS messages in Attentive in real time. This lets brands move past batch-and-blast campaigns and send texts that are actually relevant to what the customer just did, matching the personalization already built into their email programs. - Extend email-level personalization logic to your SMS channel - Increase SMS engagement rates with behavior-triggered rather than scheduled sends - Create consistent brand experiences across every digital touchpoint ## Templates ### New Attentive SMS Subscriber to Klaviyo Profile Sync Automatically creates or updates a Klaviyo contact profile whenever a new subscriber opts into SMS through Attentive, including consent status, acquisition source, and custom attributes, then enrolls them in the appropriate Klaviyo welcome email flow. Connectors used: Attentive Mobile, Klaviyo ### Klaviyo Segment to Attentive Custom Audience Sync Periodically syncs a defined Klaviyo segment — VIP customers, high-LTV buyers, or churn-risk users — to a corresponding custom segment in Attentive Mobile so SMS campaigns can target the same refined audience without manual list exports. Connectors used: Klaviyo, Attentive Mobile ### Attentive SMS Opt-Out Suppression Sync to Klaviyo Listens for STOP or unsubscribe events in Attentive Mobile and immediately adds the corresponding contact to Klaviyo's suppression list, so compliance is enforced across both channels without any manual action. Connectors used: Attentive Mobile, Klaviyo ### Abandoned Cart Multi-Channel Recovery Sequence Orchestrates a coordinated cart abandonment recovery flow that sends an initial Klaviyo email, waits for a defined engagement window, then triggers an Attentive SMS follow-up for contacts who didn't open or click the email — suppressing all messages once a purchase is detected. Connectors used: Attentive Mobile, Klaviyo ### Post-Purchase Order Event Routing to Both Channels Routes completed order events to both Attentive Mobile and Klaviyo at the same time, triggering an SMS order confirmation through Attentive and a post-purchase email sequence in Klaviyo, with deduplication logic to prevent double-messaging. Connectors used: Attentive Mobile, Klaviyo ### Winback List Push from Klaviyo Predictive Analytics to Attentive Uses Klaviyo's predicted churn and customer lifetime value data to identify lapsed customers and automatically exports them to Attentive Mobile as a targeted SMS winback audience, then feeds engagement and conversion outcomes back to Klaviyo to close the loop. Connectors used: Klaviyo, Attentive Mobile ## Challenges Tray.ai solves ### Keeping Subscriber Lists in Real-Time Sync Attentive and Klaviyo each maintain their own subscriber databases, and discrepancies accumulate fast as customers opt in, opt out, make purchases, or update their preferences. Manual list reconciliation is time-consuming, error-prone, and often means messaging contacts with stale or incorrect data. **How Tray.ai helps:** tray.ai's event-driven workflow engine listens for subscriber changes in either platform and propagates updates in real time via API, so both systems always reflect current opt-in status, contact attributes, and segment membership without manual intervention or scheduled batch jobs. ### Maintaining Compliance Across Two Opt-In Systems TCPA compliance for SMS and CAN-SPAM compliance for email both carry real legal weight, and managing consent across two separate platforms creates risk. An opt-out recorded in Attentive that isn't mirrored in Klaviyo — or vice versa — can result in regulatory violations and damage to sender reputation. **How Tray.ai helps:** tray.ai automates bidirectional suppression syncing so any opt-out or unsubscribe event in either platform is immediately reflected in the other. Built-in error handling and retry logic ensure compliance events are never silently dropped, and audit logs give you a clear record of every suppression action taken. ### Avoiding Message Duplication and Customer Fatigue Without a coordination layer between Attentive and Klaviyo, customers can easily receive redundant messages — an SMS and an email firing at the same time for the same event. That erodes trust, drives up unsubscribe rates, and makes campaign performance data harder to read. **How Tray.ai helps:** tray.ai workflows include conditional branching and timing controls that enforce channel sequencing. Marketers can define rules like 'send SMS only if email is unopened after X hours' or 'suppress SMS for customers who converted via email,' keeping the experience coherent without duplicated touchpoints. ### Mapping Disparate Data Schemas Between Platforms Attentive and Klaviyo use different data models, field names, and identifier formats. A subscriber's profile in Klaviyo may use email as the primary key while Attentive keys on phone number, which creates lookup and deduplication headaches when syncing records or events between the two systems. **How Tray.ai helps:** tray.ai's visual data mapper and built-in transformation functions let teams define field mappings, normalization rules, and identifier resolution logic without writing code. Phone number formatting, email validation, and cross-platform ID matching are handled natively within the workflow, preventing data integrity issues downstream. ### Scaling Automation as Audience and Campaign Volume Grows As a brand's subscriber base grows into the hundreds of thousands or millions, point-to-point API integrations between Attentive and Klaviyo become bottlenecks. High-volume event bursts — a flash sale triggering simultaneous sends across both platforms — can overwhelm fragile custom scripts and cause delays or data loss. **How Tray.ai helps:** tray.ai runs on horizontally scalable infrastructure that handles high-throughput event processing with built-in queuing, rate-limit management, and automatic retries. Whether you're processing thousands of simultaneous opt-in events or syncing multi-million-row segments, tray.ai stays reliable without requiring your team to manage infrastructure. ## Learn more - Intelligent Integration: https://tray.ai/platform/intelligent-ipaas/ - Merlin Agent Builder: https://tray.ai/platform/merlin-agent-builder/ - Agent Gateway for MCP: https://tray.ai/platform/agent-gateway/ - Book a demo: https://tray.ai/contact/
