I'd go with option D. The missing records are probably part of a control group to measure the effectiveness of the campaign. Gotta keep those data scientists happy, you know?
Hmm, I'm not sure. Option C seems plausible too. Those missing records could have been rejected as spam by the email service provider. Better double-check the deliverability settings.
I think option B is the correct answer. The missing records are likely part of an A/B test group, where a subset of the records are being compared to the main campaign for optimization purposes.
