You don’t want to leave your Prelaunch Community hanging. Not only will that turn those early supporters away, but also anyone else who comes after and sees a lack of engagement on your behalf.
For that reason, you shouldn’t put off responding to comments for more than a day. This will get the person commenting to come back and subscribe or reserve if they hadn’t already, keep engaging, and keep new people coming and engaging.
You’ll get automatic notifications on Prelaunch.com every time someone comments, to help make sure you don’t miss anything.
