Which criteria does Marketo use to divide the audience into A and B?
I've done an A/B test using the whole email variation test type with an audience of 3000 people. The A/B test was done on everyone (I’ve selected 100% thus I haven’t selected any winner criteria). So far 1 email got 45% more opens than the other (that’s about 60 people). I’m confused because the subject and preview text are the same… the low opens one even had slightly more delivered (10+ people) than the other one.
The audience for the test is big enough to make a statistically significant conclusion that the subject line or/and preview text in As is much better than in B however it’s not the case since both are the same.
Any idea why that would happen?
Which criteria does Marketo use to divide the audience into A and B?
How Marketo makes sure that audience A has the same attributes as the audience B?
I feel like Marketo didn’t divide the audiences “fairly”
My issue now is how can I rely on Marketo to run the A/B test for us?
