When creating a new Campaign, you can select whether to 'Remove recipients after connection', which means that we'll automatically remove a recipient once they connect. You'll be able to do so under 'Settings'.
By default, we remove recipients from a campaign when they connect. A connect means that they replied to your email, or that you connected over the phone. If you’d like to keep a recipient on a campaign regardless of whether they connect, simply uncheck. This can be useful if you’re setting up an onboarding campaign, for example. You’ll still be able to remove recipients one-off or in bulk.
