Any event should be prepared well so that your guests feel at ease and get a positive impression of your company.
For example, it is important that all of your guests receive a written invitation. So that you do not lose sight of the purpose of the event, you should also set an objective. For example, you can aim to personally make a certain number of new contacts. Of course, you must collect the contact details of all of the visitors who you did not know before - after all, that is the point of the event. A small raffle, for example, is a good way to do this.
