How I just love it when I check up my email and I get a positive comment from a publisher, even if my manuscript 'isn't for them' or 'not what they are looking for at present'. It keeps me buoyant in the tide of rejections to know that my 'premise proves interesting' and 'my writing is near poetic in places'!!
What is even nicer are the snippets of constructive criticism. Like the nuggets of gold that they are, publishers and editors use them sparingly it seems!
