It's been several weeks that I sent an email regarding to an open call for a position. The position is advertised in a personal webpage with the message "[...] suitable candidates feel free to contact me," as opposed to the "job vacancies" page which the faculty has. There is no mentioned deadline.
I have mistakenly used my commercial email address instead of my academic email address. I know that some people filter the incoming emails with respect to the domain name to reduce the number of spams in the primary inbox folder. I am afraid that this is the case.
So, I am considering to send a follow-up (duplicate) email to make sure that the email reached to the person. However, I am not sure how to word the email as I blindly assume that the person uses such filter.
Please note that I am perfectly fine with the idea of my assumption being wrong and the person choosing to ignore my email since I am not a good enough candidate. My concern is that I am a considerable candidate but I might have lost my chance because of some technical issue.
The best outline I have come up with is to write "(please ignore if duplicate)" in the subject, and blame my email provider in the first sentence, and then copy/paste the rest of the mail.
What is the least annoying way to recieve a potential duplicate email?
