If you have an online website for your business, it is vital that you have an email server as well. This does not need to be one specifically created for your business, but you do need to have a way for people to email you.
Regardless of what contact details you have available, emailing is one of the most common ways customers will send enquires including questions and reviews to businesses. Without this information on your website, you are limiting the ways people are able to contact you.
This is something that is extremely easy to add to your website. It can even just be an additional line of text showcasing an email address. But you will find by having this you are able to receive more enquiries, as well as more positive reviews.
If you are unsure of how to begin an email server or set-up an email address. Talk to your website developers and they will be happy to include this on your website.
