ColdOpenRate

Why This is an Opportunity

Sales teams obsess over subject lines but track them in scattered spreadsheets or expensive tools. A lightweight leaderboard that gamifies it is both fun to use and a no-brainer purchase for small agencies.

Key Pain Points

  • Your best-performing subject line is buried in someone's personal notes and nobody else on the team knows about it
  • Tools like Mailchimp track opens for newsletters but not for one-off cold emails and follow-ups
  • New hires waste weeks testing subject lines that a teammate already proved don't work
  • There's no shared memory for what's been tried — people keep re-testing the same bad ideas

Original Discovery

Agencies and consultants send cold emails but have no idea which SUBJECT LINES are actually working across their whole team. ColdOpenRate is a dead-simple shared scoreboard where your team pastes subject lines, logs opens/replies, and the best performers bubble up with stats. It's like a fantasy football league but for cold outreach — competitive, visible, and weirdly addictive.
