The context for a communication will determine the level of formality you should use. Where you are still establishing a relationship, err on the side of a more formal address. Over time, you might then become more familiar. For external letters and emails, use these formats:
| Letter | Dear Chris / Mr Brown Yours sincerely |
| First email | Dear Kim / Ms White Kind regards |
| Later emails, once you have a rapport | Hi Kim Kind regards / Many thanks |
Always include your email signature with your full name and phone number so your reader doesn’t have to trawl through long email chains if they need to call you.
And always keep an eye on your reader’s preferences for opening and closing text. If they do not match a more informal approach, it is best to align your style to theirs.
