You will be able to see who received the varients in the standard A/B testing. The only con is that the test will run for a specific amount of time before the winner is sent to the remaining members of the target audience. You could actually just set the test to 100% so that all people recieve the original test. My only concern with an 8 subject test is that you have a list large enough to provide you with meaningful results.
I have to test two emails with different bodies. If I use the a/b test function, and set the test sample to 100% would it be sent 50/50? I'm not looking for a clear winner just would like to distinguish how well the two compared to each other. If I do that, do you know if I would lose any information like click/ open rate?
If you are running a batch, just use the built in functionality. The only caveats are
- record the data you get from the reports in another sheet
- you can use Was Sent Email with Test Variant to see leads.
