Thank you for your critic. Yes, of course I take it as a constructive one. I have honestly felt the same way, by reading it yesterday evening, although not at all speaking and writing it correctly myself. It must sound terrible to native English speakers.
I will forward this suggestion to the responsible at Sinar.
Thanks again and best regards,
I'd like to offer a little constructive criticism. As a native English speaker, I find it annoying to read things in English that are either written by people who use English as a second language or by people who don't seem to care how something comes across and do a lousy job of translating.
There are sections of your newsletter that just don't read correctly, is their not a way of sending the text you have got to somebody who could read the information and simply re-write it so that it reads properly? English can be seen as a default language for all sorts of advertising literature, with just a little more effort it would come across in a much more professional fashion. It wouldn't take more than 20 mins to convert what you have produced to plain English.
There is great information in your newsletter, I'm sure that if you start from a grammatically correct point, then both native and non native speakers would get much more from it.
PS. This is a genuinely constructive post, please don't take it any other way!
