How to talk to customers with low AOV?

Hi everyone in Klaviyo community,

I have a challenge that I can’t seem to figure out and some ideas would mean a lot. 

I have a lot of first-time byers with low AOV ($10 - $20) which I see as a great opportunity to follow up, but I can’t seem to find a way to communicate with them and have them come back. I have a lot of different products in different categories and not sure how to segment them or build a post purchase flow for them.
My repeat customer rate is 9-10%.

Thanks in advance,

Snow
