Send custom marketing email based on product variant purchased

[RachelS20]

I am looking for a solution in Shopify or via an 3rd party app to send custom marketing email based on product variant purchased. Better if it offers a free plan.

So far I can only find solutions to send custom emails based on a specific product order, but not to variant level.

Have installed Shopsync but so far didn't find this option available 😞
