Susan Cain uses Kit (formerly ConvertKit) to power her Quiet Life newsletter and connect with her global audience. As the #1 New York Times bestselling author of Quiet, her endorsement carries serious weight in the creator economy. She's built a thriving community around introversion using Kit's creator-focused platform.

Susan chose Kit because it's built specifically for creators like authors and thought leaders who need to nurture deep audience relationships. Her psychology-focused content requires sophisticated audience segmentation to deliver personalized insights about introversion. Kit's creator-centric features let her build meaningful connections rather than just blast generic emails. The platform's focus on helping creators monetize their expertise aligns perfectly with her book sales and speaking business.

Subscriber Tagging

Susan can segment her audience based on interests like workplace introversion, parenting introverted children, or leadership styles. This lets her deliver targeted psychological insights that resonate with each subscriber's specific situation. The tagging system ensures her content feels personal and relevant to each reader's introversion journey.

Visual Automation Builder

Susan uses automated sequences to nurture new subscribers with her core introversion concepts over time. The visual builder lets her create educational email courses that guide readers through her psychology frameworks. This automation helps her scale her impact while maintaining the thoughtful, research-backed approach her audience expects.

Kit is an email marketing platform built by Nathan Barry, a creator who found existing tools impossibly complicated for people building audiences. Unlike generic tools like Mailchimp, Kit is designed specifically for creators — with 99.8% delivery rates, 40%+ open rates, and built-in commerce that lets you sell directly through email. Over 600,000+ creators use Kit to serve 587M+ subscribers and generate $42 for every $1 spent.

You build automated email sequences using Kit's drag-and-drop Visual Automation Builder — welcome series, product launches, nurture campaigns that run 24/7. Tag subscribers by interest and behavior, then send targeted emails to exactly the right people. Sell digital products, build landing pages, and grow through Kit's Creator Network where creators cross-promote each other's newsletters.

Automate follow-up sequences that deliver your best content while you're traveling to the next event. Segment by event type so corporate workshop attendees don't get the same emails as conference keynote viewers.

"Even more than social, email is the way. Kit is more central to me than any publication."
