Hello Community,
I’m digging into the mailjet API creating a double opt in workflow for the GDPR compliance. I´m wondering if anyone already built one. Please let me know 
Cheers!
so mailjet has that double opt-in built into their contact list settings - you enable it on the list itself in mailjet dashboard, not really something you build in n8n.
when you add a contact via the mailjet node in n8n to a list with double opt-in enabled, mailjet automatically sends the confirmation email and only activates them after they click. your workflow just needs to add the contact to the right list and mailjet handles the rest.
