Why do campaigns fail?
Campaign publication is executed at the time you request your campaign to be published, but sometimes, due to Facebook's structure, it is not always successful on the first attempt. When a campaign fails to publish, we automatically retry several times before declaring the campaign a failure.
We will usually write to you within 48 hours of a campaign failing to let you know that the failure is not something we can help with, and that something must be modified in the campaign. You may find more information about a campaign's failure status sooner directly in your ad manager.
What can I do about it?
We recommend that if a specific campaign should start on a certain day, to set it to start at least the day before. Outside of publication issues, there is always the possibility that ads are disapproved, so you usually want to plan campaigns in advance anyway.
Trying to recreate and publish the same campaign usually doesn't help the situation and you risk ending up with two duplicate campaigns. Just drop us a line at support and we can investigate and publish the campaign for you.

What if I don't want to have my campaign published anymore?
That's no problem. See this article to delete the campaign.
