Answer all of the customer's questions
You might not think you need a lesson about answering all of the customer's questions in an email. Most of us think we've answered everything the customer asked, but we've usually missed a few questions along the way. All day long, customers are asking us the same thing, over and over, so it's easy to skip a question. This lesson offers some simple advice, be sure you've answered all the customer's questions. Sometimes the customer's questions in an email are easy to see. You just look for the question marks.
If you do a quick read of this email from Safeek, you'll see that he's asked two questions. Can I pay by check and if so, what is the process? A complete reply to Safeek looks like this, Dear Safeek, Yes, you can pay for your transcript by check. Just complete the attached transcript request form, then mail the form and the check to the Office of the Registrar. That was pretty straightforward, but in some customers' emails, questions can be difficult to see, especially if the email is long or disorganized.
