Old Hack, I've just been and reread the OP and as far as I can tell the topic is that the poster was asked to email a full, did so, and received no acknowledgement.
How exactly are my comments that not acknowledging email is rude, not on topic? My comments were about agents who don't acknowledge submissions, so not, as you rightly point out, the majority, but apparently the agent with whom the OP is dealing.
Sophie, Sophie, Sophie.
You need to reread the original post in this thread, I think. Let me help you with that:
About four months ago I sent a query to an agent using their agency’s online form. A few days later I got an email from the agent asking for the full.
[...]
I did not get a confirmation that my full was received. After no response I sent a polite nudge at the three month mark. Now almost a month later, I still have gotten no response.
[...]
Would it be out of line for me to call or contact the agent/agency about this?
Those among us who have been blessed by the gods of good reading comprehension will understand that the original post was about whether or not the OP should phone the agent to check whether or not her full had been received; it was not about how agents who don't acknowledge receipt are "lazy, rude and shitty", which is what you wrote, and which is what I took exception to.
If you want to try to bicker with me you're welcome to, but you will receive a time-out for doing so. Just so we're clear. Now, back on topic, please. For the second time. Thank you.
