I need advice on how to market my product

Hey everyone,

My recent side project is called Notifiverr. It's a browser extension to show notifications for Buyer Requests on Fiverr and therefore support you to get more sales. I have released the extension 5 days ago and until now I wasn't able to gain a relevant amount of traction.

What I've tried:

• Posted in multiple Fiverr related Facebook groups
• Cold DMed users who promoted their Fiverr gigs on Twitter and Facebook
• Made posts on 2 subreddits

You can check out the website here:

As a developer with little marketing knowledge I would really appreciate tips and ideas on how I could improve my strategy to gain more customers for my product.
