Hey @Alex Osipov60! It's currently not possible for the same Sequence email to be received more than once by the same Subscriber, unfortunately 😞 So if you wanted your Subscribers to receive the same email weekly, there would have to be a new email for each week (even if the content was the same). I'm sorry about that!
That said, if you'd like to request this as a feature, you can do so here57! We always appreciate the feedback 🙂
