Below are some features of a cover letter except?a.Dateb.Letter numberc.Subscriptiond.Recipient address

The feature that is not typically included in a cover letter is b. Letter number.

Here's why:

a. Date: This is necessary in a cover letter. It helps to track when the letter was sent or received.

b. Letter number: This is not a common feature in a cover letter. Cover letters are typically not numbered as they are standalone documents that accompany a resume or CV.

c. Subscription: If by "subscription" you mean the closing salutation (like "Sincerely" or "Best regards"), then yes, this is a typical feature of a cover letter.

d. Recipient address: This is also a common feature in a cover letter. It shows that you know who you are sending the letter to and that it is not a generic letter.
