Do your employees use email addresses like:
mary@yahoo.co.uk
sales@mycompany.btconnect.com

Wouldn't you like them to have:
mary@yourcompanyname.co.uk
sales@yourcompanyname.com

With an email hosting package you can have professional looking email addresses. Once you have decided upon your domain name you can add any person's name before the @ sign of your choosing, even 'sales', 'info', 'enquiries' etc.

You will also be able to utilise this name as your website. So if you currently use: www.mycompany.btconnect.co.uk........ you could have....
www.yourcompanyname.co.uk
