Create Mailing List of Scottish Secondary Schools

I want all the admin email addresses for all current secondary schools in Scotland, of which there are around 364. The admin email address would be the public email address for the school office. This information is available from the Education Scotland website, where you can do a search for the contact details of all Scottish secondary schools <[login to view URL]>. This produces a list of Scottish secondary schools, where you would then click on the name of each school to bring up the contact details. The finished work can simply be an email containing all the school admin email addresses, or an Excel spreadsheet, whatever suits. The work must be accurate.
