OK found after clicking dates around - to last 7 days and then back to this month

Weird but has been found 

Hi @DarleenW,

I’m glad to hear you were able to locate the campaign.

All campaigns will be accessible through the Campaigns tab in the Klaviyo dashboard. 

Keep in mind that by default, Klaviyo will display all emails that are in scheduled or draft mode (even if you use “in the last X amount of days”) filter. In the future, you may find it easier to also use the more filters button to to further narrow down the results. For example, by “sent” status only which would further refine your search and eliminate emails in draft or scheduled status.
