HarperCollins sends two emails on day 0: a welcome message about exclusive content, deals and book news, followed by a 40% sale email with a discount code, book recommendations and genre links. The sequence then moves to an onboarding email on day 1, a sale email about pre-orders on day 2, and three messages on day 3. This creates a concentrated early cadence rather than a single welcome touchpoint.
The three-email welcome series consists of the day 0 welcome, the day 1 request for a birthday and favourite genres, and the day 3 reminder about the welcome offer. Sale messages arrive around that sequence rather than waiting for it to finish. Later, the brand sends a sale message on day 5, then a product launch and a re-engagement email on day 7.
The early sale emails use 40% off, while the day 3 messages move to 50% off all books and introduce midnight urgency. The day 5 email keeps the 50% offer but adds a competition for free books linked to eligible order values. Every email through day 5 includes a discount code, making the offer easy to carry from the message to checkout.
HarperCollins repeats the sale while changing the framing: recommendations in ", you might like these books 📚", pre-orders in "Books to pre-order!", then final-day language in "50% off all books! Sale ends today🚨". Product grids appear in several of these emails, while countdowns are used in the welcome reminder and the deadline-led sale messages. Genre links give readers another way into the store, and some sale emails offer a pause or opt-out from future sale messages.
Most subject lines include an emoji, often alongside a direct promise or deadline. Examples include "Welcome , to HarperCollins Books 📚", "Don't forget your welcome offer 📚⭐" and "Divergent like you've never seen before💥". The wording shifts from welcome and discovery to urgency, while the launch email uses a recognisable series title to introduce The Sixth Faction.
Preview text adds useful context when it is present. "And they're 40% off! 😍" complements the recommendation subject, while "Don't miss out!" and "Treat yourself, you deserve it 💛" reinforce the sale's deadline framing. The re-engagement email takes a different route with "Long time, no read" and "Let's reconnect!", asking inactive readers to share preferences so future emails can feature relevant books, releases, deals and giveaways.
