Spark Unveils Redesigned Email Experience for iOS 26
Sep 11, 2025
Spark, the award-winning email app used by more than 15 million people worldwide, today announced a major makeover of its iPhone and iPad apps to coincide with the launch of iOS 26. This update marks Spark’s most significant redesign in the past five years, introducing a modern, expressive interface built to showcase Apple’s new Liquid Glass design language.
Exclusive to devices running iOS 26, Spark’s latest update fully embraces Liquid Glass, Apple’s biggest visual update since iOS 7. Key highlights include:
- Redesigned inbox: Spark’s inbox now features a floating Liquid Glass bar that moves search and calendar to the bottom — putting both within easy reach when checking emails with one hand.
- Immersive mail view: Collapsible Liquid Glass toolbars give messages maximum focus when scrolling. A glassy contextual menu replaces the previous action sheet, offering a sleeker and faster way to access Quick Replies, integrations, and other actions.
- Improved search and navigation: The search experience has been streamlined for usability: The search field is now positioned directly above the keyboard, offering a more efficient and familiar way to find emails, senders, and attachments. The clearer separation between controls and content enables users to focus on important emails without distraction.
- New expressive app icon: Spark’s icon has been crafted with multiple layers of Liquid Glass, creating a luminous effect that sparkles in Light, Dark, and Mono modes.
“Apple continues to push the boundaries of design with Liquid Glass, adding depth and expressiveness to the iOS experience,” said Alex Tyagulsky, Head of Spark and Co-founder of Readdle. “With this update, we embrace Apple’s latest design language to make Spark’s unique email experience feel even more delightful and tactile for millions of people around the world.”
The new update will be available when iOS 26 launches on September 15, with additional enhancements rolling out in the coming weeks. Spark is available as a free download on the App Store.
