- Writing style tip: how to write greetings and sign-offs
Greetings and sign-offs vary depending on the formality of the communication.
Greetings and sign-offs in letters
In letters, the conventional greeting is:
Dear Sally (without a comma)
If you don’t know the person, some writers address the person as Mr/Ms or, alternatively, use their full name.
Dear Sally Smith
Dear Ms SmithTraditionally, letters were signed off with Yours faithfully or Yours sincerely, depending on the writer’s relationship with the person.
Yours faithfully was used in formal letters where the writer did not know the recipient personally. (These letters generally began with the greeting, Dear Sir/Madam or To whom it may concern.)
Yours sincerely was used when the writer knew the person or was writing more informally.
These days, many organisations choose to use Yours sincerely for all letters. Some even sign them off with Kind regards or Regards.
As with the greeting, you do not need any commas after the sign-off.
Yours faithfully
Email greetings and sign-offs
The way you use greetings and sign-offs in your emails depends largely on your relationship with the person you are emailing. Often, you can mimic the style or tone of greeting and sign-off of the person you are emailing.
In emails, the most commonly used greeting is:
Hi Sally
However, some writers still choose to use Dear when writing more formal emails to clients, or when addressing a group of people.
Dear Jim Smith
Dear allThere are several ways of signing off emails. Some of the most common are:
Regards
Kind regards

- Writing style tip: how to write about money
In business writing, currency is usually expressed in symbols and figures ($10).
When writing about different currencies that use the dollar, your style choices are a:
- Letter or letters symbolising the country, followed by the $ sign (This is the style recommended by the Reserve Bank of Australia.)

Millions
When writing about millions and billions, many writers use the full word in the text and either m or M and bn in tables and brackets.
10 million (10m) or 10 million (10M)
10 billion (10bn)Most organisations use a space before million but not before m or M.
$96 million
$96mM or m?
Under ISO 1000:1992/Amd 1:1998, which Australia and New Zealand adhere to, millions should be represented by M. However, according to the Australian Government’s style manual (2002), m is preferable to M as long as the context is clear.
monies or moneys?
In everyday usage, most people don’t pluralise money, but in tax and accounting material, it can be made plural for individual sums of moneys/monies and either moneys or monies is acceptable. Just be consistent. The Australian Taxation Office website uses both words interchangeably.
You can’t reclaim moneys/monies already invested.
