Double Optin not working with Mailerlite

Hi, some time ago I already posted the problem that the workflow "create or update subscriber" for mailerlite does not trigger a double optin. See

In February it worked finally. But now I set up a new workflow and unfortunately no double optin is triggert again ... The confusing thing about this workflow is that I have to choose whether a subscriber is active, unconfirmed or inactive. Last time the double optin worked with the setting to "active".

Why is this such a big problem? I do not understand why it worked once and now is not again?

Hope, you find a solution for this.

Many thanks, Sophie

I had a discussion with the technical team regarding your issue, and they have informed me that we have followed Mailerlite's API documentation to create this action step. According to the documentation, double opt-in should work when the status is set to 'Active.' Although we have sent multiple emails to Mailerlite's team regarding this issue, we have not yet received a reply. I recommend that you also reach out to their support team regarding the same matter.
