According to the EU General Data Protection Regulation (EU GDPR), the explicit consent of a user is required when you wish to process their personal data. The double opt-in offers the opportunity to obtain such a declaration of consent.

Process

When you activate the double opt-in feature and the user submits the form, it does not get the special state received and the workflow is not run. That is, no workflow actions are run yet. 

Instead, an email with a confirmation link is sent to the user. Once the user clicks on this link, their submission is confirmed and workflow processing starts. The confirmation link can only be used once and is then no longer valid. This lets you obtain a user's consent before you process their data.

The email address to which the confirmation link is sent is usually obtained from the form itself via variables.

Configuration

You can open the configuration dialog for the double opt-in via the corresponding button in the form menu. There are a number of required fields that are necessary for setting up the double opt-in feature.

Required fields

Email to

Indicates to whom the email should be sent with the confirmation link. Typically, the e-mail address is obtained via Platzhalter.

Email from

Specifies the sender address of the double opt-in mail.

Subject

Specifies the subject of the double opt-in mail.

Message

The message to be sent with the double opt-in mail. This should contain the confirmation link. The confirmation link is available via the Platzhalter [%$FORM_VERIFY_LINK%]. If the message is left blank, a standard message will be sent with the confirmation link.

Optional information

Sender name

Specifies the name of the sender of the double opt-in mail.

Result pages

By default, the system templates for double opt-in are sent for the three cases  double opt-in email sent ,  double opt-in successfully completed  and  double opt-in failed. Via  Dateien & Templates > HTML in the menu you can create and design your own answer pages.

Double opt-in email sent

The page that appears after submitting the form and the double opt-in email.

Double opt-in successful

The page that is shown after clicking on the double opt-in link.

Double opt-in verification failed

Delete automatically

Datasets that have not been confirmed can be automatically deleted. If no time is specified, the data is saved permanently.
