Sorry for my poor [insert-language]
Please don’t apologise for your ‘poor english’.
It’s far far better than my russian, polish, german, italian, french, spanish, hungarian, svensk, or any other language except english.
I get quite a lot of emails from russia and poland (where a lot of stock photographers are) and almost all of them apologise for their english. Please don’t, I understand, and if I wasn’t so crap at languages I’d learn at least a bit of yours, but I just have not talent for it.
So once and for all, I apologise for my poor <your-language>, and thank you for learning mine to a point at which we can communicate :)
