To find the list of people who received the losing email, they would use the Was Sent Email filter with the Test Variant constraint. This filter allows them to specify which email and which test variant they want to target. The Was Sent A/B Test filter does not have a Variant constraint, and it is not possible to see who received which test variant without using a constraint. 

The marketer should wait 24 hours for the updated period cost to be reflected in RCE. This is because RCE data is refreshed once a day, usually at night. Therefore, any changes made to the period cost or other program attributes will not be visible in RCE until the next day. RCE does not update in real time, and the updated period cost will be reflected in RCE eventually.

A best practice for A/B testing is to run a combination of many tests sequentially and methodically. This will help the marketer optimize their email performance by testing one element at a time and measuring its impact on key metrics such as open rate, click rate, conversion rate, etc. Varying as many elements as possible in each test or ending the test as soon as one version surpasses the other are not best practices for A/B testing, as they can lead to inaccurate or inconclusive results.
