开展联系人定向推广活动时，是否能排除现有客户？

Yes, you can exclude existing customers when running a contact targeting campaign on LinkedIn. This is a crucial feature for optimizing your ad spend and campaign effectiveness. By uploading a list of your existing customers as an exclusion audience, you prevent your ads from being shown to people who have already converted or are already engaged with your business. This allows you to focus your budget on reaching new prospects who are more likely to convert, improving your return on ad spend (ROAS). Not excluding existing customers would lead to wasted ad impressions and potentially annoy your current client base with irrelevant ads.
