I have been waiting over a week for a response to an email I sent to someone I engage in a professional capacity . There is no out of office set up . He may be on holiday , he may think my enquiry is not important , he may be snowed under and cannot answer at the moment , it may have gone in his junk folder for the first time . I just don’t know . Given my question is about something I need to submit to another organisation I would like a response but clearly don’t want to irritate . When I was working we sent a holding message just to let the recipient know we’d received their message and have an answer within the week. Maybe it’s not a thing anymore .
