Hello Guys, I'm a fresh graduate in marketing and yesterday I've got my first marketing job, I'm struggling because there's no head of marketer to ask for help, I'm all alone, So can you guys help me with sharing resources or informing what are the basic forms I should have and if there's important tips you can guys share ,I'm totally new , I know I can excel in it but I just need help to start in the right way...Would appreciate your help!
