Thanks for covering the Jetpack release. I just wanted to take a second and clarify one thing. The Jetpack Newsletter Sign-Up Form works similarly to all other Jetpack forms.

The submission is stored in the Feedback section of wp-admin. Visitors who submit a form and opt-in will have additional meta data saved to that submission which is labeled as email_marketing_consent and set to 1, noting their permission to be emailed.

These form submissions are easily exportable to be used however site admins prefer, and can be used by third-party plugins. We have included an optional but preferred integration with Creative Mail which will automatically turn those submissions into a mailing list.

As always, I’m happy to answer any other questions, and I look forward to see how this form helps everyone improve their marketing.
