We’ll use a "Welcome / Referral program" campaign as an example. ## Searching by campaign status In the **Campaigns** filter group, select the status you need. ​ Each status has a nested filter — **Campaign** — pick the one you need. * Find customers who were sent the campaign. * Find customers who were unable to send the campaign. * Find customers who were unable to deliver the campaign. * Find customers who were in the campaign recipient list but could not receive it due to a send or delivery failure. * Find customers who received the campaign. There is no separate "Delivered" status. To find these customers, set the following two conditions: "The campaign was sent" and "There were no campaign delivery failures." * Find customers who opened the campaign. * Find customers who didn’t open the campaign. **Note:** Make sure to include **campaign sends** in the filter. Otherwise, customers who weren’t included in the recipient list may appear as well, since they have no opens for the selected campaign. * Find customers who clicked on a link in the campaign. * Find customers who did not click in the campaign. * Find customers who clicked the unsubscribe link. * Find all campaign participants — all customers who were included in the campaign’s recipient list. ## Searching by interaction time * Find customers who opened the campaign in June 2024. * Find customers who opened the campaign within the last hour. ## Searching by number of interactions * Find customers who clicked in the campaign two or more times. * Find customers who were sent the campaign three times in the last six months. # How to find specific Campaign engagements (e.g. clicked, sent, opened etc.) Go to **Customer Data Platform → Campaign engagements**. * Find campaign sends. * Find campaign opens. * Find campaign clicks in the last 24 hours.
