I need you to go to these publications, look at some articles there and find the emails of reporters that wrote them. I need the First name, last name, email I am allocating 5 hours work to this. If you have already DONE this work for past clients and have a list, please contact me. thanks! Email: Hi *Reporter Name*, I've been reading some of your articles, so I thought you might be interested in this revolutionary new social media platform that my team and I made. My name is Matt and I'm the Founder of ReelTalk - we are a new app launching this month. Here's a video of what our app does - 'Reel Talk Video Link' ReelTalk focuses on bringing trending movements. For, example the Area 51 raid got over 3 million people to join! That's the kind of movement that we are focused on! Here's what makes us special - ReelTalk brings you closer to others that share your beliefs, and it helps you engage with new ideas. Superficial media has proved the opposite, and it often alienates us. There is always an opposite side to every opinion, and this is the platform that unites validation with controversy. A stranger’s profile is then viewed as their identity and not their photo album from Hawaii. ReelTalk wants to show all the commonalities between us, so no one feels isolated. It is less about double-tapping a picture and all about creating meaningful connections. Are you interested in jumping on the phone with me so I can tell you more about how we want to make social media more useful and positive? Matt
