[Question] Double opt-in via SDK

[matthiasnagel]

Feature question

Feature
This issue relates to be GDPR compliant in general. This means to have a double opt-in option like with form builder so the user receives an email where she finally can sign up for the newsletter.

Question
Is there any option like that and if not is that on your schedule?

Hi Mattias,
The Mobile SDK does support GDPR through Marketing Permissions. But there's a little setup needed. You'll first need to enable GDPR in your audience sign up form. This article explains how to do that: https://mailchimp.com/help/collect-consent-with-gdpr-forms/#Set_up_your_GDPR-friendly_signup_form

Once it's setup on your sign up form, you can get the marketingPermissionId and details from the API Keys page by your key -> View Marketing Permissions. Here's an article that explains that: https://mailchimp.com/help/mobile-sdk/#Set_marketing_permissions

Once you have the marketingPermissionId this part of the README explains enabling those during signup in the SDK: https://github.com/mailchimp/Mailchimp-SDK-iOS#marketing-permissions
Let us know if you have any other questions.

Hi @michael-heard-mc,

thanks for your reply and the instructions. I followed your steps but this is not triggering any double opt in email to the user where she can confirm double opt in. This email functionality is also not described in the documentation.

From my perspective this whole functionality is missing in the mobile SDK. If you look at the contact status, there should be another state for users who subscribed but did not accept double opt in yet. Maybe there should be a function which can trigger the double opt in email. I hope you can follow me?

Best,
Matthias

Hi @matthiasnagel,
Thanks for the reply. I follow now. You're correct the Mobile SDK does not currently support double opt-in. That's a great feature request though, I'll make sure to add it to our list. That being said, our public api does support double opt-in. If you add a subscriber with the "pending" status.

I can't speak to specific laws but if you have any follow-up questions regarding GDPR, please feel free to reach out to our legal team at legal@mailchimp.com.
