Adding to an Existing List and Using the Always Append Feature

The list type does not affect functionality in any way, and is merely a method for you to organize your records and workflow. You can collect data from several forms in a single list.  If you want to collect data from several forms, you will not have a list that is dedicated to the form. This makes it easy to use the list to respond to specific form submissions.

Follow the steps below to ensure that the new form writes into an existing Act-On list:

• Click on Content, and click Forms.
• Click New.
• In the properties tab of the form settings, select the four-lined icon on the far right that will bring up a window of your current account lists. From here you can select an existing form submission or marketing list to submit to.
• After selecting a list, verify that your fields are in alignment so when submitting to this existing list it does not duplicate list columns. 

Using Always Append

Once you've created the new form submission list, you'll notice a checkbox called Always Append.  By default, this feature is disabled. By keeping it disabled, the Act-On form will allow duplicate submissions based on the email address; however, Act-On will simply update the previous form submission with the new form submission. For example, if john@abc.com submitted the form twice, the form submission list will overwrite the first submission with the information from the second submission.

If you enable the Always Append feature, the Act-On form will allow duplicate submissions based on email addresses. For example, if john@abc.com submitted the form twice, the form submission list will contain two entries for john@abc.com and treat them as unique submissions.
