Gretchen Rubin uses Kit (formerly ConvertKit) to manage her email marketing and connect with her audience of happiness and habits enthusiasts. As a #1 New York Times bestselling author and host of the popular Happier podcast, her tool choices carry significant weight in the creator economy.

Rubin chose Kit because it's built specifically for creators like authors and podcasters who need to nurture long-term relationships with their audience. The platform's focus on subscriber segmentation and automation perfectly matches her need to deliver personalized content about happiness and habits to different reader interests. Kit's creator-friendly approach aligns with her business model of building a loyal community rather than just pushing products.

Subscriber Tagging

Rubin can tag subscribers based on their interests — whether they're more focused on happiness research, habit formation, or specific book topics. This allows her to send highly targeted content that resonates with each subscriber's particular journey. With her diverse content spanning multiple books and podcast topics, precise segmentation is crucial.

Visual Automation Builder

The automation builder lets Rubin create sophisticated email sequences that guide new subscribers through her key concepts and book recommendations. She can set up nurture campaigns that introduce people to her Four Tendencies framework or Happiness Project methodology without manual intervention.

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.

Segment by event type so corporate workshop attendees don't get the same emails as conference keynote viewers.
