Prepopulate campaign forms using link parameters

To streamline the participation process in your sweepstakes or photo contest, you can pre-populate the submission form with relevant information from your email service provider's database. This feature allows you to pass along details such as email addresses, first names, and any other available information, making it convenient for participants to join. Here's how you can structure the URL to achieve this:

1. **Access the Custom Form Editor**: Navigate to the settings section and locate the custom form editor. This is where you can view and edit the fields of your submission form.

2. **Identify Field Names**: In the custom form editor, note the exact names of the data fields you want to pre-populate, such as email and first name.

3. **Craft the URL**: Begin by appending parameters to the campaign URL. The first parameter should start with a question mark (?), followed by the field name (e.g., email), an equal sign (=), and the value to be inserted.

4. **Add Additional Parameters**: For subsequent fields, use an ampersand (&) to separate parameters. Include the field name, an equal sign, and the corresponding value. Repeat this step for each field you want to pre-populate.

5. **Example URL Structure**:

   ```

   CampaignURL?email=test@test.com&first=John&last=Doe

   ```

6. **Dynamic Population**: When recipients click on the URL in the email you send them, their email service provider automatically inserts the relevant information into the corresponding fields of the submission form.

By leveraging this feature, you can simplify the entry process for participants and ensure accurate data collection for your sweepstakes or photo contest.
