Feel free to customize it based on the unique needs of your audience! You can always do it one way, get feedback, and then try it the other way, get feedback, and compare. (Data is always the best teacher.)
Many people also just like to “collect” these lessons to take action on later, at their own pace. It’s probably pretty unlikely that someone will receive, open, and take action on every email in real-time.
The overall goal is to show up consistently in someone’s inbox with helpful content, show that you know your stuff on this topic and can deliver a quick win (whatever you promised in your “hook”) and get them excited to stay on your email list and keep learning from you.
I don’t think sending every day or every other day would be a make-it-or-break-it decision, so just go with whatever feels best for you.
