Step-by-Step Guide
Follow these steps to obtain subsequent consent from your contacts:
1. Create the DOI Mailing
First, create the desired DOI mailing. Make absolutely sure that the DOI confirmation link is included, and activate the mailing in the final step.
Tip: Since you are writing to existing contacts, we recommend adjusting the text to transparently explain why a renewed confirmation (re-opt-in) is required.
2. Create a Provisional Subscription Form
Now, create a provisional subscription form. This form serves purely as a technical trigger for sending the DOI and will not be visible to your contacts.
To keep things organized, it is best to give the form a clear name (e.g., "DOI Campaign Re-opt-in").
In the first step of the form setup, select the previously created DOI mailing that you want to send.
3. Prepare Recipients and Start the Import
Navigate to Recipients → Add Recipients and start importing your file. If you do not have the data as a file yet, you can download it beforehand from the address book using the "Export as CSV" button.
⚠️ Important before importing: For security reasons, a DOI mailing is only sent to contacts who are not yet active in the system. Therefore, you must delete these recipients from the current address book before starting the new import.
4. Activate DOI Mailing
During the intermediate step of the import process, map the corresponding attributes (data fields) and activate the option "Send Double Opt-In mailing".
5. Select Form and Address Book
After activation, a pop-up window will appear. Since subscription forms can be linked to multiple address books, you have two options for the data destination:
"Current address book": The recipients will be added directly to the address book where you are currently running the import.
"Address books of the subscription form": The recipients will be assigned to the address books configured within the form.
Next, select the provisional subscription form you created earlier. This selection determines which specific DOI mailing will be sent to the contacts. Confirm your selection.
6. Run and Complete the DOI Import
Now, start the final import, which will simultaneously trigger the dispatch of the DOI mailing.
Result: The imported contacts will only be added (back) as "active recipients" to your address book once they have successfully confirmed the DOI link in the email. Contacts who do not click the link will not be saved in the address book.
