I have magazine publishers/editors ask me for a manuscript after sending a query letter but then they never wrote back to say they wanted it or didn’t want it. Should I e-mail them and ask if they got it or wait? And how long should I wait? Are they being rude or am I being anxious?
If I were you, I would wait about a month to prod them for a response.
When sending out future queries, include a note that says something like this:
Since sp*m filters are such a problem, please confirm you received this on arrival.
