The situation is like this. I made a new submission to a journal via their website; I am under the impression that an author would automatically receive a copy of the generated PDF file for review and the acknowledgement of receipt, just like many journals more or less do. However, after one business day, there was still nothing about this matter that came into my inbox (used in a generic sense, including spam). I thus wrote to the editor in chief regarding this matter. The editor has not yet replied for a day (which is unusual according to the editor's known pattern in dealing with submissions). There is no email for the editorial assistant that I can find on their website, even if the position exists.
Now the question is how then a safe next move would be like. I cannot just wait indefinitely; potential possibilities are fading. But it also seems that it is difficult to make the intention to ``set a deadline for response" sound innocuous. I am asking if there is a relatively common practice our there or an all-considering well-rounded strategy regarding this matter that could serve as a signal for the editor to know my intention without tearing anyone's face.
