    I was tired of writing HTML emails so I built something that works▲10

    Hey HN, I was tired of writing HTML emails and one day was going through reddit specifically searching for people who hated writing HTML emails and heard a lot of complaints from solopreneurs and marketers as this is a very boring task and many marketers and solo founders have much more important tasks to take care off. So I decided to build HTML email to solve this. My friends have already saved hours using this product. This is my 11th product and I think this solves a problem many folks are struggling with. Feel free to share your views.
