Closing the Letter. Choose a Closing: One must use a proper closing in a business letter. Use a comma (,) after it. Sign the Letter: Always sign the letter in ink. If sending a printed copy, always affix the scanned signature. Make Note of Enclosure: One must properly enclose a list of attached documents with the letter. One can use the abbreviation of the enclosure, i.e., Encl. or Enc.
Finalizing the Letter. Edit and Review: Once you are finished with writing the letter, try to look for errors. Check for spellings, punctuations, grammatical errors. Don’t Staple the Letter: Use a paperclip on the top of the left corner if there are many pages. Use of staple doesn’t look nice for a business letter. Posting of the Letter: Always use clear and correct spelling for mentioning the name and address of the recipient.
