Re: Correct this tender please
With regard to how you should address this letter, if you know the name of the person you are writing to, you should use that ("Dear Mr Smith"). If you do not know the name, then use "Dear Sir/Madam". If you know perhaps the job title you could use "FAO Senior Tender Officer" (or whatever the job title is). "FAO" = For the attention of.
