Built with Kit

Email Marketing System for Fast-Growing Thriller Author

Natalie Vijlbrief

The Challenge
This fiction author writes thrillers and was experiencing explosive growth through advertising, but his email system couldn't keep up. Everything was self-built in Mailchimp, and he wasn't confident he was doing it right. With his subscriber list growing from 8,000 to over 20,000 in just five weeks, he needed a platform and strategy that could scale with his success and actually sell his books.
The Solution
I migrated him from Mailchimp to Kit and built a complete email marketing system from scratch, designed specifically for authors managing rapid growth and multiple reader segments.
What I delivered:
Complete platform migration from Mailchimp to Kit (20,000+ subscribers)
Welcome sequence for new readers that introduces the author and his thriller series
Free sample chapter delivery system to hook new subscribers
Book sales automation sequences to convert readers into buyers
Segmentation strategy to separate readers by genre preferences (thrillers vs other genres)
Additional segmentation for aspiring writers in his audience (a significant subset who engage differently)
Data collection strategy to gather more subscriber information for future targeted campaigns
Ongoing optimisation as his list continues to grow
The Results
He now has a professional email marketing system that can handle his rapid growth and actually helps sell his books instead of just sending newsletters. The segmentation allows him to speak differently to thriller fans versus aspiring writers, and the automated sequences ensure new subscribers immediately get value and are introduced to his books. With projections showing he'll reach 50,000 subscribers by the end of the year, the system is built to scale seamlessly as his audience continues to grow. With a clear system in place, he can focus on writing and advertising while his email marketing runs smoothly in the background.
