@vitbarreto Another approach to consider is you can set “properties” on a link click. So, if you setup the link properly for each product link, it can update a custom property like “product_interest = XYZ” where “product_interest” is the custom property name, and “XYZ” is the product value.
Then, when your product XYZ is back in stock, you can simply build a segment of people who’s custom property “product_interest” is “XYZ” and send a targeted campaign to those folks (repeat for each product). It’s certainly not as automated and elegant as the Back In Stock Triggered Flow, but might be a workaround.
See here for how to do this:
Include Ratings Links or NPS Surveys in an Email
The example in the documentation walks you through a “NPS Survey” - but it can also work for any custom property.
