Hurricane: Every agent has a different method of dealing with queries, so it's difficult to tell, but, viewing his timeline, it appears as though he was spending a lot of time on queries for a while and then paused. While only he can say why, a good guess might be that he's decided to spend more time on reading new manuscripts and/or managing existing clients. In any case, it's still very, very early to be panicking about a query. Also, agents are normal people, and the vast number of them are very reasonable. I'm sure he wouldn't discard your query just because you forgot something in the Subject line.
As for nudging, there are no easy answers. It is something you have to evaluate on a case-by-case basis after carefully reviewing each agency's rules.

Greyowlstudio: Thanks for the reply! I'm still new to querying so I'm not sure about nudge etiquette. My concern is because Mr. Morgan seems to have a pretty fast response time but hasn't responded to any queries for almost 2 weeks so I'm not sure whether it's the time of year or whether some didn't get delivered/got buried

Hurricane: Foundry Literary + Media say the following on their website: "If you do not receive a response within eight weeks, your submission is not right for our lists at this time."

Unfortunately, that's not much help in your situation if you're worried that your query got lost. The point however is that a 'nudge' is apparently not appropriate in this case. Why would you assume your query is lost? 2-3 weeks is nothing as far as query wait times go.

When should we nudge our query? I’m suddenly worried mine wasn’t delivered or got buried because of the long weekend.

Profile Update: Profile reviewed. No Changes.

Hi,

Thank you for your submission.

Unfortunately, I did not connect with the submitted material enough to consider your project for representation.

I wish that I had the time to respond to everyone with critical feedback. There’s simply not enough time in the day, thus the form response. This business is incredibly subjective and I have seen authors that I pass on go on to critical and commercial success. What might not work for me might be the perfect thing for the next agent on your list.

Again, thank you for the opportunity to consider your work and I wish you the best of success with your current and future writing endeavors.


Best,

Sam Morgan
