Project ideas from Hacker News discussions.

We have a 99% email reputation, but Gmail disagrees

Hacker News Discussion

📝 Discussion Summary (Click to expand)

Four dominant themes from thediscussion

  1. Gmail’s reputation system penalises irregular or Kickstarter‑related outreach

    “Kickstarter spam is a huge problem, seriously, it is so prevalent I expect gmail may even have specific rules around it.” — rokkamokka

  2. Many users feel forced into unwanted subscriptions, violating explicit opt‑in expectations > “How do you get email addresses? Do people freely and explicitly choose to sign up to your mailing list, or is it baggage that you’re forcing on them without their consent?” — younen

  3. Technical mis‑configurations (e.g., splitting verification and marketing from different sub‑domains) confuse spam filters

    “But even worse than that, the ‘confirm your email’ email and the following ‘finish account setup’ email came from two different sub‑domains.” — kodebach

  4. When unsubscribe links don’t work or are hidden, users mark the mail as spam, further damaging sender reputation

    “There are tons of companies that I have told to stop sending me emails that just… continue to do so. And some that won’t allow me to tell them to stop (I need to create an account to tell them not to email me…).” — RHSeeger

🚀 Project Ideas
