Hi @kchung thanks for posting in the Klaviyo community! When looking at the metrics section, there isn’t an easy way to identify which profiles are suppressed or not; however, you can create a segment of people where checkout started at least once during the time period you’re after, and then include the parameter 

AND

person is not suppressed for email

Then you could export this segment to see how much those people are worth. You could also add a parameter in the segment about whether or not they also placed order in that time period. 

Here’s a little bit of information from Klaviyo about setting up segments

Here’s more information about metrics as well.
