To: All Company EmployeesFrom: Greny Hawking, Chief of the Clerical OfficeDate: September 27 ,2009Subject: A gentle reminderGood aftemoon, citizens of Synjones Corporation,It has been impressed upon me the need for a gentle reminder regarding the sending and receiving of mail at our faility.Any incoming mail should have the company name on it, in addition to the name of the actual recipient. Let me write that again this way: Any incoming mail should have the COMPANY NAME on it in adition to the NAME OF THE RECIPIENT. I'm not shouting at you, the large caps were added for emphasis. I only hope to stress the importance of this information on incoming mail because we have had instances where the post office has, in their ongoing effort to decrease mis deliveries, returmed mail intended for us to the sender because it lacked a company name. While we still receive mail for other companies in the building, the post office has returmed invoices, statements and other materials intended for us due toa lack of a company name. So please emphasize all potential senders the importance of including our proud company name along with your own.Conversely, we have witnessed some peculiar things while handling outgoing mail. Not wishing to draw undue attention to any particular individuals, let's just say matter of fact that it's okay to remove the backing of the mailing label and apply the sticky side to the top of the package that you are sending. Taping the label to the package defeats the intended purpose of the nice adhesive that's been placed there for us. The following formula has been tested and proven successful: place contents into packaging, seal package, apply label with recipient information to the package face, and attach completed shipping form. if those steps can be followed, we can almost assure, barring any interference from God or human failure, that your goods will reach the desired location within the desired time.Thank you as always for your cooperation. To: All StaffFrom: Melissa Witt, the Head HonchoDate: June 1, 2009Subject: New Memo Format EffectiveIn order to make interoffice communications easier, please adhere to the ollowing guidelines for writing effective memos:.
