How to report performance of abandoned cart automation

[kubrina]

I have a 3 step automation sequence for abandoned carts, and now I'm looking for a straightforward way to report on its performance.

The sequence is built with Omnisend. It has two emails and an SMS. For each step, I'd like to get the number of carts recovered and the value of the carts recovered.

I'd prefer a straightforward attribution, which I think would be last click. 

What's the best way to get this info? All the links are UTM-tagged.

Thanks in advance.
