Dynamic lists are mostly used when you need a list that is based on prospect data that changes and prospects will be added or removed automatically based on the criteria. Users can’t manually add or remove prospects from a dynamic list.
Prospects also cannot add themselves to the dynamic list via the preference page, but they can opt out of the list.
Note: When the dynamic list is created, the cambodia phone number prospect will automatically be opted-in to this list so it’s important to acquire explicit consent before creating the list.

If the prospect chooses to opt out of the list, they are not technically removed from the list in Pardot, but they will no longer receive any email communications from that dynamic list. You’ll see that the status within the list changes. To clarify what is meant by this, see the screenshot below.

If you’ve decided to make your dynamic list public, only the prospects who meet the lists criteria can see the list of the email preference page.
Therefore, if you want prospects to be able to opt-in to a list via your email preference centre, do not make the list Dynamic, keep it as a public static list. This is because the dynamic list will automatically tick whoever meets the initial criteria and will remain that way until the prospect opts out.
