Humble Bundle sends eight emails over four days, counted from signup, moving from a broad welcome to product education, a Choice invitation, and a time-limited offer. It closes with store discovery, social channels, and more bundles and courses.

On day 0, the welcome email introduces the Humble community, its charitable mission, and its main offerings: Humble Choice, bundles, the store, and publishing. Its single CTA gives the email one clear call to action. The preview text frames the proposition: “Time to get great games, books & software at great prices—all while supporting charity.”
On day 1, two onboarding emails turn that overview into product education. “Get bundles full of games, books, and software at great prices” explains the pay-what-you-want model, charitable giving, and current bundles. The other, “Level up your skills in Linux, Kubernetes, and more!”, focuses on learning bundles and software offerings. Together, the emails cover distinct parts of Humble’s catalog.
On day 2, the first upgrade email introduces the paid membership through “Play the best of Humble every month with Humble Choice”. Its content gives the membership several concrete features: monthly games, the Humble Games Collection, store savings, and charity support. Like the welcome email and the day 1 bundle email, it uses a single CTA.
On day 3, Humble sends an onboarding email about the store before sending a second upgrade email. The store message highlights thousands of games on sale, charitable giving, and member savings. The later message changes the Choice pitch into a time-limited offer: “Cool weather, hot deal: Get Choice with this special offer!” Its content includes a one-month discount, a single-use coupon, an expiration date, and limited availability, and the email uses a countdown. Here, product information comes before the time-limited offer.
On day 4, the plain-text email “Follow us for the latest Humble news and deals” invites subscribers to follow Humble’s social channels and blog. Its content points to bundle news, store deals, charity updates, and community discussions.
The last onboarding email returns to catalog discovery with minifigure designs from SkullForge Studios and courses related to Scrum, Jira, and AI. Its subject, “Up your arsenal with the hottest minifigure designs by SkullForge Studios!”, highlights a specific bundle offering, while its preview text mentions the courses. The sequence therefore ends with another discovery-oriented email after the Choice offer, rather than ending on the offer itself.
