Our abandonment rate has been higher than I'd like for a couple of months and I haven't landed on a fix yet. People get most of the way through checkout or spend real time on a product page, then drop off without any clear signal why. Some recover on their own within a day or two. Most don't.

I've got a recovery flow running on email and I've been testing SMS on top of it, but I honestly can't tell how much of the return traffic is the emails doing their job versus people just remembering to come back on their own. Splitting the flow based on exactly what was in the cart versus sending a generic reminder feels like it should matter more than it does sometimes.

I'm stumped. What's actually working for people running abandonment flows right now? Email only, SMS on top, retargeting ads, some mix of those? And more specifically, how are you sequencing it, timing wise and message wise?

I'm not looking for the textbook answer, I'm more interested in what you've tested and kept because it worked.
