I did set up an A/B test and we got a winning variation (OR: 23.4%) that was sent to the remaining audience but we recorded a poor OR of 1.8%.
As I seeded myself into the audience, I received the winning variation into my inbox (not spam).
2% open rate seems to be wrong both variations recorded approx 23% open rate.
We have already waited 48 hours and I assume we won’t see much more open.
How can you explain this massive difference?
