# Email Subject Line Variant Log

## Inputs
The approved variant list, the test export with send volumes and results, and the team's minimum sample rule.

## Workflow
1. List approved variants and their send volumes.
2. Record the supplied results per variant.
3. Flag variants below the minimum sample rule.
4. Return the log without declaring a winner.

## Output contract
Variant | sends | supplied result | sample flag | owner

## Fictional acceptance test
Fictional test: 3 variants with sends of 5000, 4800 and 300. The supplied minimum sample is 1000. Flag only the 300-send variant as below sample; report no winner.
