It's not impossible - but usually authors are pretty keen to advertise what the higher tiers give you. Which is generally more advance chapters. Maybe discord benefits, extra side-story chapters, access to in-progress/draft chapters, or author Q&A sessions. I've never seen notification e-mails listed as a benefit. Almighty coincidence that e-mail notifications are always reserved for the earliest access tier, but every author has forgotten to advertise the benefit.
