i was searching for newsletter from physics related topics but i couldn't find, told my friends they were also facing same problem. So i decided to build free open to all platform where authors will list their newsletter for free and reader can find them with one search. This is whole mission of building this platform. So i request you all to go submit first newsletter on my platform and tell your friends and help to spread the word. Thank you so much for your time.
