    It's my first time launching my own SaaS. I planned to develop it with a friend, but he refused to work with me because his developer skills are higher (in his opinion). I developed a simple online email scraper by keyword, hashtag, or followers using Google Search as a source of data (with Dorks) I will be glad to receive any feedback and suggestions.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
