I have a question about sequences. We have created a sequence which has an immediate email that goes out + 7 days of emails following that. When people sign up through our form, we want them to receive the first email immediately, but we'd like to prompt the sequence of 7 other emails to go out on the day our event actually begins. Subscribers can not start receiving the full sequence right away because they will be signing up in advance. Is there a way to manually tell Convertkit to continue with the rest of the sequence when our event begins? We are promoting this event in advance and people are signing up at different times so we need to actually activate the rest of the sequence that is related to the event on the day the actual event starts.
