Hello @Viktor Stykow, Thank you for reaching out.......!!!
To send past customers to the Reviews.io collector page via Klaviyo, you can create a one-time campaign with personalized review links instead of relying on flows, which are limited by real-time triggers like "Order Fulfilled." First, export past customer data from Klaviyo, including their email addresses. Next, generate unique review links for each customer using the Reviews.io format:
https://www.reviews.io/store/review?store=YourBrand&email=customer@email.com
Replace "customer@email.com" with each customer's actual email address. Once the review links are created, upload them back into Klaviyo as a custom property for each profile (e.g., review_link). Then, create an email campaign targeting these past customers, inserting their unique review links dynamically using Klaviyo’s personalization syntax:
Click [here]({{ person|lookup:'review_link' }}) to leave a review!
This approach allows you to request reviews from customers even months after their purchase. Alternatively, if you prefer an automated solution, Reviews.io Booster can handle this process, though it may require additional costs. Let me know if you need assistance with any step.
