A professional automatic reply email is good when it is written with clarity. However, it is not necessary to start with ‘Dear esteemed customer’, you can start with ‘Dear friend’ or “Hi there” in order to create a good atmosphere of relationship with your customers.
The following example is an email that is clearly written.
Hey there, Thank you for your email. Please note that we currently have some slow-downs on our service due to the ongoing upgrade of our network which started 9:00am on the 22nd of July, 2016 and will last until 12 noon on the 25th of July, 2016. In spite of the upgrade, you can still visit our website and check out the previously asked questions about our products. This will give you some clues about the enquiries you want to make. We promise to get back to you as soon as our network services are upgraded. Best regards, Ananthu Parollil Communications Director Pears and Cares Limited
