The email I have just sent to an accountancy firm.
To whom it may concern,
I have recently set up my own Limited company. As a result I have been
inundated with letters from banks and accountancy firms, like yours.
While I appreciate this is a good way for you to find new clients, I
am afraid you lost any interest from me after the second word of your
letter, which is "Sir" ie Dear Sir....
I am astonished that you default to assuming an MD is male.
It is quite clear from my name ([obvious female name) that I am female.
Please correct this.
Best wishes,
[obvious female name]
