Before distributing a report, a marketing analyst notices that the total distinct promotional email messages is less than the combined total of emails sent. Which of the following is the most likely r

If aggregation did not include all emails, both 'total distinct' and 'combined total' would be lower, but the relationship between them might not specifically cause the distinct count to be less than the combined total in this manner.

Emails not being delivered would affect the 'delivered' count, not necessarily the 'sent' count, and would not explain why the distinct messages are fewer than the total sent.

If the report failed to run properly, the numbers might be inaccurate or missing, but it doesn't directly explain this specific relationship between distinct messages and total sent.

If a recipient received duplicate emails, the 'total emails sent' count would increase for each duplicate, but the 'total distinct promotional email messages' count would remain the same for that unique message. This scenario directly explains why the combined total sent would be higher than the distinct message count.
