Hi,  
  
  
  
I tried to do some email A/B testing and encountered some oddities. This is how I set it up:

- Created a lead list including 60 leads  
- Created a template email  
- Created a A/B testing variant from the template email (weight = 50%, winner criteria = email read rate)  
- Sent out the email via a campaign  
  
  
  
The weight worked, both variants were sent out to 30 leads.  
  
  
  
When I am in the email detail view of the basic variant, I can toggle the stats between **Variant** and **All**. In both cases it shows the same values, which is the stats of the basic variant (I expected the sum of both variants). When I am switching to the A/B testing variant, I again can toggle the stats between **Variant** and **All**. However, in **Variant** mode it shows the stats of the A/B testing variant (= correct). When I switch to **All** , the stats from the basic variant are shown - again I expected the sum of both variants.  
  
  
  
Do I have an error in reasoning? Does the system behave as expected or is there an error?  
  
  
  
Thank you,  
  
Peter
