Question
A/B testing

Asked a question 2 years ago

I sent my first broadcast email today, and I used A/B testing for my subject line. In my report, it says each one sent to 7 recipients for a total of 14, but at the top under stats it says it was sent to 41 recipients. What happened to the other 27? And it says Option A won even though they both had 7, so I don't get how it was chosen as the winner when it was equal to option B. Can someone explain how none of these numbers make sense?

Here are all the details48 on how ConvertKit does A/B testing, but let me give you the highlights:

  • ConvertKit will send option A to 15% of the list, and option to 15% of the list.   Note that 7 is about 15% of 41 (with some rounding occurring).
  • Four hours later, ConvertKit will send the message to the other 70% of your list using whichever subject line "won" in the testing.   This is the other 27 folks in your example.
  • Lastly, with the numbers you're sharing, a split test is not going to be statistically significant.  In general you'll need a list of over 1,000 folks to have it show meaningful differences.
