"Only unique leads" option
Double messaging someone can turn into a real disaster - and we want to prevent that.
If you’re running multiple campaigns, and don’t want to send messages from different campaigns to a lead, or to send connection requests when it’s already pending or already on LinkedIn - you should check our Advanced settings, as shown below.
Click on the Only unique leads option, and make sure those leads are not discovered and steps are not executed on them.
Have in mind that this applies to the leads from all of the campaigns on your account.
