A developer posted this on the WordPress support forums:
"We'd like to send the auto-reply email after a visitor submits a CF7 form directly from Mailchimp. We have a drip campaign set up and a dedicated Mailchimp list. Is it possible to sign up everyone that submits a contact form to this list without displaying a checkbox?"
The reply was a link to a code snippet for setting a Mailchimp tag on CF7 submission. One sentence. Thread closed.
That answer is technically correct but skips everything that matters: how Mailchimp's automation system actually works, what the consent implications of silent opt-in are, and how to build the full CF7 to Mailchimp automation flow properly.
This post covers all of it.
