The combined power of Loop and Klaviyo
Loop Subscriptions: more than just a subscription app

Klaviyo: Expertise in automated marketing
For its part, Klaviyo has established itself as a particularly powerful marketing automation platform. It allows merchants to create personalized communications at scale, whether by email or SMS.
Its ability to leverage customer data to precisely segment audiences and trigger automated message sequences makes it a valuable tool for any customer engagement strategy.
Strategic advantages of Loop-Klaviyo integration
The connection between these two platforms creates a particularly effective synergy for optimizing your subscription strategy:
1. Real-time synchronization of subscription events
The integration automatically transmits all subscription-related events in Loop to Klaviyo, including:
- Creation of a new subscription
- Pausing or resuming a subscription
- Cancellation or reactivation
- Upcoming or skipped orders
- Failed payments
This real-time synchronization allows you to react promptly to every change in your customers' subscription journey.
2. Enrichment of customer profiles with subscription attributes
The integration automatically enriches Klaviyo profiles with valuable data from Loop:
- Active subscriber status
- Number of active subscriptions
- Next billing date
- Subscribed products
- Order history processed
- Revenue generated by subscriptions
These attributes enable ultra-precise audience segmentation for perfectly targeted communications.
3. Creation of contextual communication flows
Thanks to this integration, you can design message sequences triggered by specific subscription events:
- Welcome sequence after subscription creation
- Reminder before an upcoming order
- Recovery after a failed payment
- Re-engagement after a pause
- Win-back after a cancellation
These automated flows allow you to support your subscribers at each stage of their journey with relevant and timely messages.
4. Advanced segmentation based on subscription behaviors
The integration allows you to create highly specific segments:
- Active vs. inactive subscribers
- Subscribers to particular products
- Customers who canceled for a specific reason
- Subscribers with failed payments
- Members close to their renewal date
This granularity in segmentation allows you to finely adapt your communication according to each subscriber's profile and behavior.

Practical use cases and advanced strategies
Now that the integration is in place, let's explore some concrete scenarios to maximize its potential:
Strategy 1: Optimizing new subscriber onboarding
Create a sophisticated welcome flow for new subscribers:
- Personalized welcome message immediately after registration
- Educational email about product usage 2 days later
- Presentation of the customer portal and self-management features
- Friendly reminder before the first delivery
- Feedback request after receiving the first product
This sequence establishes a strong relationship from the start and reduces the risk of early cancellation.
Strategy 2: Reducing churn rate
Implement a proactive strategy to prevent cancellations:
- Identify warning signs (skipped orders, frequent portal visits)
- Trigger preventive communications with value-added offers
- After a cancellation, send a personalized win-back sequence based on the cancellation reason
- Propose suitable alternatives (temporary pause, reduced frequency, different product)
This approach allows you to recover subscribers who are about to leave or have recently canceled.
Strategy 3: Maximizing customer lifetime value
Increase the average basket size of your current subscribers:
- Recommend complementary products based on their current subscription
- Send exclusive offers to add products to their next delivery
- Propose strategic upgrades to premium versions
- Reward loyalty with progressive benefits
This strategy transforms your subscribers into high-value customers.
Strategy 4: Recovering failed payments
Minimize losses due to payment issues:
- Immediately alert the customer after a failed payment
- Send progressive reminders with clear instructions
- Offer alternative payment options
- Propose an incentive for quick update of payment information
This approach can significantly reduce involuntary churn due to payment problems.
