The modern professional must have two things together when applying for a new job: a well formatted resume and a good introduction letter.
Date _ In both formats, the date is the next element to appear after your address, and falls on the left hand side (after a line space). The correct style for the date is month, date (comma) year. Name And Address Of Recipient _ The recipient's address is set to the left of the letter in both formats, but do be aware of the need to ensure this is visible if using a window envelope. If you're sending the letter in a windowless envelope, just ensure that the recipient's address appears exactly as it will on the envelope.
