When you join Perfect Audience, the first Facebook or web retargeting campaign you launch will be completely free for 2 weeks after it launches or until it reaches $100 in spend.
You'll receive an e-mail 2 days before your campaign's free trial expires to let you know. If your campaign is still active at the end of the trial period, we will automatically switch it from free trial mode to full mode and bill you for the current pay period's budget. This ensures continuity of ad serving.
Advertisers are limited to one free trial campaign, which can be launched as soon as your site's 'All Visitors' retargeting list has cookied 250 visitors in a 7 day period.
