Hi there,
Since this question relates to the premium features of Download After Email Plus (add-on), this ticket has been answered via our website. What pertains to the free version is covered below.
Whether the optional checkbox is checked can differ per download form (so this value can be overwritten in the database and is therefore not suitable for use). For the agreement it’s important to know whether the optional checkbox has been ticked at least once. The date on which this checkbox has been checked for the first time can be found in the opt-in time column.
In the admin notification email you can see if the optional checkbox has been checked for that particular download form.
To prevent people from using fake email addresses, you can choose to only import subscribers after a second opt-in (= clicking on the download link), whereby it is confirmed that the subscriber is actually the owner of that email address. In this way a high quality subscribers list can be built up.
If you have any more questions, feel free to ask.
Kind regards,
Team Download After Email
