# Why Has the Data on My Banner Campaign Changed?

Occasionally, you may notice changes in the reported data for your banner campaigns in Opensense. These discrepancies can generally be traced to the following reasons:

## 1. Ongoing Engagement with Expired Campaigns

When a banner campaign reaches its scheduled end date, it does not immediately become inactive in all recipient inboxes. Recipients may still have access to emails containing the campaign banner, and may continue to engage with it even after the original campaign has expired. As a result, your engagement data may reflect new activity beyond the scheduled dates.

## 2. Modifying Scheduled Campaign Dates

Adjusting the start or end dates of a banner campaign after it has been created can significantly impact your data. For instance, if a campaign was initially scheduled from 9/1/25 to 10/1/25 and you later change the end date to 10/1/25 (after expiration), the system will only aggregate data for that singular day. This can result in apparent data loss or unusual reporting for your campaign.

### Recommendation

To maintain accurate reporting and historical data integrity:

- Avoid modifying the scheduled dates of a banner campaign after it has been created or has expired.
- If changes are unavoidable, document adjustments for future reference and reporting accuracy.

By following these best practices, you can ensure consistency in your campaign metrics and avoid unexpected changes in your reporting data.
