Target your customers more specifically with a new filter to exclude customers who have already bought a specific product of yours.
You can use this feature to up-sell a bundle to folks that bought one of your cheaper products. Or let all your customers know, ten days after launch, about your new product–without annoying those that have already purchased it.
You can access the “did not buy” filter for all of your new Updates and Workflows. Note that this is a pro feature. Enjoy!
