Recently I launched a new product in a very competitive category, and suddenly for 3 months almost no user who registered , knowing that I added it in several platforms as a producthunt .., I also tried the cold mail but anyway without any success, people don't even want to try my product for free for 14 days,
My question, can I concider that my product is dead? if not, can you suggest some effective marketing channels for me,
Note that for last 3 months the product has cost me more than $ 100 / month without any active users,
Thank you in advance
