Capitalisation in Letters, Emails, Headings & Lists

When you write a letter, an email or a list, a few extra capital-letter habits kick in. They're easy, and getting them right makes your writing look neat and grown-up.

Why these habits are worth learning

Most of your writing is ordinary sentences, where capitals feel fairly safe: the start of a sentence, names, the word I. But the moment you write a greeting, a sign-off, a heading or a list, people start to guess. Should dear have a capital? Does every word of best wishes go up? Do bullet points start with capitals? These are exactly the spots where even adults hesitate. The good news is that the habits are calm, small and reusable. Learn them once and you will stop second-guessing every first letter, and your letters and lists will look properly finished.

Letters and emails

Start the sign-off with a capital, but only the first word:

Best wishes, · Kind regards, · Thanks,

Start the greeting with a capital, and capitalise the person's name:

Dear Miss Patel, · Hi Tom,

Notice wishes and regards stay lowercase, only the first word of the sign-off is capital. Writing Best Wishes or Kind Regards with two capitals is a very common slip, born of trying to look polite. One capital is all you need. And do not add surprise capitals in the middle of a greeting either: Hi Dear Colleague is not warmer, just odd.

Subject lines

An email subject line is a small label, so treat it like a short heading, not a full sentence. Capitalise the first word and any names, and leave the rest quiet: History homework question, Drama club moved to Friday. What does not work is shouting the whole line in capitals, HISTORY HOMEWORK QUESTION, which reads as if you are cross, nor leaving it all lowercase, which looks as though you could not be bothered.

Headings

Give a heading a capital at the start, just like a sentence, or use title case like a book title:

My trip to the museum · How plants grow

If you have several headings and subheadings in a longer piece, it helps to make the levels look a little different, so a reader can see the structure at a glance. Just keep each level consistent: if your first subheading is in sentence case, keep the others the same way rather than switching about.

Lists

If each item in a list is a full sentence, start it with a capital and end it with a full stop:

Remember to:

• Bring your kit.
• Check the time.

If the items are just short words or phrases finishing off the opening line, lowercase is fine, and you leave off the full stops:

Please bring:

• a packed lunch
• a water bottle
• £5 for the trip

The one rule that really matters with lists is to be consistent. Pick one shape, all full sentences or all short fragments, and use it right down the list. A list that mixes the two, one capital sentence sitting among lowercase scraps, is the thing that looks untidy even when nobody can say why.

A second look at sign-offs

Sign-offs are worth a closer look, because they are where the "only the first word" rule really earns its keep. Whatever phrase you choose, only the very first word takes a capital, and the rest follows the ordinary shape of the words: Yours sincerely, Yours faithfully, Best regards, Kind regards, Many thanks, All the best. So it is Kind regards, with a small r, not Kind Regards. In a formal letter, if you began with a name, Dear Miss Owen, you end with Yours sincerely; if you had to write Dear Sir or Madam because you did not know the name, you end with Yours faithfully. Which phrase you pick is a matter of custom and politeness, not of capitals: the first word takes the capital every single time, whichever sign-off you reach for.

The tricky edge: names always keep their capital

There is one thing that never switches off, even in a lowercase list. If an item happens to start with a name, a place, a day or the word I, that capital stays: Monday's timetable, the River Thames, £5 for the gift shop. So a fragment list is mostly lowercase, but a real name inside it still stands up tall. Do not "fix" a name to lowercase just because the rest of the list is small. The rule about names never takes a day off.

Why it matters

Letters, emails and lists are some of the most useful writing you will ever do, at school and long after. A greeting with the right capitals, a sign-off that is not nervously over-capitalised, a list that keeps one tidy shape, all of it makes you look organised and grown-up. And because a reader meets the greeting and the layout first, before they read a single sentence of what you actually want to say, these small capital habits shape the very first impression your writing makes. Getting them right is quick, and it pays off every single time you write to someone.

Answers

1. Dear Mr Jones,
2. Best wishes, (only "Best" is capital)
3. My favourite hobby (capital at the start)
4. School trip next week (sentence case, not a shout)
5. Pick one shape. As fragments: a water bottle / a hat / snacks (lowercase, no full stops). Or as sentences: Bring a water bottle. / Bring a hat. / Bring snacks. Do not mix the two.
6. Hi team, ("team" stays lowercase, it is not a name)
