Different Alerts and what they are linked to.
Alerts are there to let you know when someone has registered through a link on your website straight into an event or group on your CRM, or if you yourself have been added to a meeting. They draw your attention to an occurence on the system.
So as a user on the CRM system, if you have been added to a meeting, the person who is creating the meeting has the choice to send you an Alert - which is in the form of an email letting you know about the meeting. Please note that currently only OpenNetworks users get this alert. The basics of the meeting are outlined in the alert, and it makes you aware of the fact that you have been included in a meeting.
In the case of an external registration - so someone has registered for an event or a newsletter, the person who has registered will receive an alert mail to confirm their registration, and the user will receive an alert to let them know that someone has registered. The contact has been captured onto the CRm, amd put into the correct group or event, the mail is just to alert you to the fact that someone has registered.
When a contact updates their details (using the Update my Details link at the bottom of the bulk mails) you will also receive an alert. This lets you know that the contact has updated their details - and the new details need to be processed.
