@AC0 Klaviyo recommendations are unique to each subscriber unless it doesn’t have enough data on that individual - in that case they’d default to best sellers. They also will never recommend an item the customer has already purchased. 

Have you tested this out with some specific subscribers? If you preview the email as a specific email you’ll see exactly what they’ll see - so you can get a sense of how accurate the product recommendations are. It’s probably not as good as a 3rd party tool that focuses on personalization, but in my experience they’ve been pretty good. 

Depending on how many product categories you have, you COULD use dynamic content to show different product feeds in the same email. You’d have to tag people’s profiles to do it and then create separate product feeds based on the product categories but it’s doable. 

The only thing to watch out for is the size of your email.  Other’s have mentioned here that even though the content isn’t visible for the subscriber, the code is still there and contributes to the overall size of the email and could get clipped in gmail. I personally haven’t actually run into this; even if it has a warning in the builder. But something to be aware of. 

You could look at a tool like Nosto or other similar personalization platforms. Some of them have product recommendations that you can use with Klaviyo. 

The other thing to consider that in many cases I find just the act of sending the email is enough to get the purchase. If you have a big list, a wide product assortment and a budget to invest in a 3rd party platform to handle this, awesome… but if it’s a stretch it might not be enough of an ROI to bother. Totally depends on where you’re at in your business though. 

Hope that helps!

Is there a public api endpoint for recommendations that returns an array of product ids based on a provided profile id? In other words, if I wanted to use klaviyo’s product recs outside of email/sms.
