## Use Case : Sending unique links to attendees after the event has ended

Some organizers would like to send out unique links to their attendees after they have successfully attended an event. This can be done by using our manual email campaign. Examples of use cases that could benefit from the steps mentioned in this article include:

1. ESG events that would like to send unique carbon emission proof to attendees.
2. Academic events that would like to send unique CPD hours certification to attendees.
3. Award ceremonies or annual dinners that would like to send unique photo links to attendees.
4. Corporate events that would like to send out unique post event sales PIC contacts.

## Example use case : Calculating the level of carbon emissions for each attendee and displaying the information in email.

### Steps

1. ```
   Create custom fields on the **Registration Form** by clicking on **Manage Fields** > **Add New Field**. This will allow the attendees to input their responses when registering for your event. For example, if you need to know the transportation method of an attendee, you can craft the question accordingly. \

   ![](/files/d7PC31j3XKA6L7HZpzss)
2. Process the data on your end. For example, if you need to calculate the level of carbon emissions based on mode of transport, you can do so on your own Excel sheet. To obtain the registration form data, export the attendee list report.\
