Which factor could lead to a campaign report showing zero results after campaign delivery?

In a campaign report, several factors can contribute to showing zero results after a campaign delivery. Each of the options presents a scenario that can lead to such an outcome.

A high bounce rate indicates that a significant number of the emails sent were undeliverable. When emails bounce, it means they do not reach the intended recipients, which can severely impact the number of effective deliveries and consequently show little or no engagement in the report.

Failure to send means that the campaign was not executed at all. This could be due to technical issues, scheduling errors, or related concerns. If a campaign does not actually go out to the intended audience, it will obviously result in zero responses in the report.

Data integrity issues refer to problems with the contacts in the campaign. If the data is flawed—such as corrupted records, missing or incorrect email addresses, or improperly segmented lists—then the campaign may not reach the correct audience or any audience at all, leading to no engagement metrics being reported.

Since each of these factors—high bounce rates, failure to send, and data integrity issues—independently has the potential to result in a campaign showing zero results, the most appropriate conclusion is that all of the above scenarios could lead to the issue described.
