What points should one consider while sending a letter

When sending letters or packages through the mail, consider the following:

  • Address the envelope to the recipient by name and title.
  • Use the person’s correct address.
  • Mail the letter at least 0.7 centimeters (0.3 inches) from the edge of the envelope.
  • Seal the envelope so that it doesn’t open during transportation.
  • Print the recipient’s name in bold letters.
  • Write the sender’s name and address in the upper left corner of the envelope.
  • Write the name and address of the organization you are sending the letter to in the upper left corner.
  • When sending a large envelope or package, use the words “Do not bend.”
  • If the item is too big to fit in the mailbox, attach a small piece of paper with the word “Fragile” written on it.
