Punctuation Rules for Business Letters

Designing Your Business Communication

Pristine Foil Letterhead by PaperDirectWhile business letters can often be compelling and even fun to read, they should also showcase proper punctuation. Punctuation rules for business letters are fairly straightforward, but you can mess them up as early as the salutation.

Salutation and Closing

Business letters can feature one of two types of punctuation based on the punctuation marks you use after your salutation and closing. Mixed punctuation uses a comma after the salutation and a comma after the closing:

  • Dear Mr. Robert Edmunds,
  • Sincerely,

Open punctuation omits any type of punctuation after the salutation and closing:

  • Dear Mr. Robert Edmunds
  • Sincerely

The body of the letter follows standard punctuation guidelines, which it never hurts to review. A big change over the years has been the use of one space, instead of two, after a period. Semicolons are used when you’re combining two independent clauses. Example:

  • It was a pleasure meeting you on Friday; we look forward to working with you.

Commas have a reputation for being tricky, but two main rules can help you use them properly in business correspondence. The first is to use a comma before a short conjunction when you’re combining two independent clauses. Example:

  • It was a pleasure meeting you on Friday, and we look forward to working with you.

The second comma rule is not as strongly set in stone, and it involves the use of the comma when listing three or more items. The rule depends on whom you ask, with the AP Stylebook omitting the comma before the conjunction. Example:

  • We are ready to set up our website, launch our product and begin our first marketing campaign.

Your other option is to include a comma before the conjunction. Example:

  • We are ready to set up our website, launch our product, and begin our first marketing campaign.

Both options are technically correct, and the latter can be helpful if omitting the comma changes the meaning of the sentence. Example:

  • Our company picnic will feature hot dogs, macaroni and cheese.
  • Our company picnic will feature hot dogs, macaroni, and cheese.
