Show HN: I Built an Agent to Write Personalized Cold Email Opener

Hacker News Free Advanced

The project itself, an agent that researches a person then drafts a first line, is less important than the comment thread, where working founders argue in real time about where automated personalization stops being real and starts being fake at scale. It is a good place to see the counterarguments to just automate it, including from people who receive dozens of these emails a day. Read it to pressure-test whether an automated approach would actually pass your own bar for a real opener.

  • Automating the research step does not automatically make the output feel personal to the reader.
  • Experienced founders can tell an AI-drafted opener from a human one, and say so bluntly in the comments.
  • The debate in the thread is a useful check before you build or buy a personalization tool.
