Hi there @shimotomoki,
Thanks for reaching out!
So if I got it right, you’d like all your WordPress users to have a status of Subscribed when they register. Is that correct?
You can achieve that only if you follow all of these steps:
– disable Sign-up confirmation email in MailPoet > Settings > Sign-up confirmation tab (you have to use a third-party sending service to make this change);
– disable “Subscribe in registration form” in MailPoet > Settings > Basics tab.
If you use MailPoet Sending Service, it’s not possible to subscribe users who didn’t opt-in and haven’t confirmed their email.
I hope this clarifies a bit, but please let us know if you have any questions!
