Cookies and email marketing

Where you receive a marketing email, event invitation or other direct mailing from us, we may collect information about you in the following ways.

View as web page: If you click on the "view it as a web page" link, a session cookie is recorded by us so that the web page is personalised in the same way as the email.

Links to web pages: If you click on any web link, we will record a session cookie and will automatically log such activity on our database.

Unsubscribe: If you click unsubscribe, we will automatically log this information on our database. If you unsubscribe from any email invitation or alert, we will continue to store your personal data on a "marketing suppression list" so as to record your preference.

Event RSVP buttons: In our event invitations and confirmations we provide buttons to allow you to accept, decline, cancel and register (if you are not the original recipient of the email) for that event. Clicking on these buttons will generate session cookies and your choice will be recorded in our database to help us manage the event.
