I got this email, not sure if it is from Riot, can some1 confirm?

I received this email, addressed to my summoner name and everything. Looks kinda legit but I'm not sure. The email address it came from either leagueoflegends@email.riotgames.com or LeagueofLegends.6flw6dfyzj.fdk6@email.riotgames.com. Especially this last address caused my suspicion since it looks so derpy. Can anyone confirm this is or isn't a legit riotgames mail, preferably someone from riot but i don't know if employees read posts like these The mail says: ''LET YOUR VOICE BE HEARD As part of our ongoing efforts to make League of Legends the best game online, we're conducting a brief survey of some of our players that you've been randomly selected to participate in. We are always looking to better understand our players and we want to hear what you have to say. Chime in, take the survey below and let us hear who you are and what you think about the game.
