What will happen after people hit Notify on my Hub Page?

Hi Everyone, I will be launching tomorrow! I see around 70 people hit notify for Brick - SaaS Starter Kit on the hub page so far here: https://www.producthunt.com/prod... What will happen once the launch is live? Does ProductHunt.com sends an email to these people? How many notify is needed to do well with launch and get some good amount of traffic in your experience? Wish me good luck!
