What would be a good subject heading when emailing principals about interviewing or being considered for an interview at their school? I have emailed dozens and have only received about 2 responses. I know P's can be busy, receive hundreds of emails in any given day, and that emails can go straight to spam..but I am wondering what would be the BEST subject heading to increase chance of them actually opening up an email from a job seeker? Side note: I also plan on sending packets eventually, but right now I am starting off with emails. Thanks!
