Dear Everyone,
Dear All,
Dear Colleagues

What should i write them?

[Maydup]

Dear All

[woofgang]

Informally dear all, formally dear colleagues.

[CrapAtCryptics]

Maybe the subject matter might flavour the title - if its a booze up Dear All if its something more formal Dear Colleagues.

[Peter Pedant]

Dear Colleagues

the course I think you are doing demands a more formal style

oh and good luck you should find the answer in the course material
( if you are doing AAT 2 or level 2 English )
