The hack
Send emails to people who commented on Product Hunt launches.
Why it works
This is similar to → Email Product Hunt makers who just launched. The difference is that this can get you to an audience of more than just makers. Most commenters on product launches have tried the product, and some are even paying for it.
How to do it
Identify relevant products
Go into the launch archive and find products that are related to the challenges your tool helps to solve.
Look beyond just direct alternatives. For example, people who commented on a tool like Ghost or Substack now already have something for sending out newsletters. What they might lack is an AI copy assistant to help them write them. Thinking like this will expand the potential pool of products and people to reach.
Email people who commented
Most commenters have their social media or websites connected. Go through them and find their emails.
