Depends on the org. It definitely makes a diff to look professional. Keep at it. Thats the secret. With covid everyone has their hands full. If you are that guy who shows up every 2 days for a month or two someone will remember you and decide to respond. Otherwise the chance of forgetting about you and your mail within 2 minutes is quite high inside a busy workplace. Best way ofcourse, is to get someone you know to put you in touch with someone inside. Then you spend time circulating till you find someone with authority to take the decision. Unless you are extremely lucky or your project is extremely interesting the whole process can take months (depending on what type of data it is).
