Once we have a big database of possible influencers, about two weeks before launch, we start reaching out to them to tell them about our project and ask if they can post about the campaign on Launch Day. For those who write back and agree to help, we follow up to provide them with sample tweets for the launch. The goal of the sample tweet is twofold: it takes the burden off of the person to come up with their own tweet, and it gives you control of what is being shared.
