Airmail vs Spark

Airmail focuses on manual power-user workflows and optional AI Composer purchases rather than a full team AI suite. Smart filtering and rules exist, but they do not match Spark's integrated AI assistant, meeting notes pipeline, or collaboration-aware automation.

Spark +AI on Plus/Pro drafts, rewrites, summarises, and powers an AI Assistant with plan-based history depth and monthly credits. Free users get only a limited preview. Meeting notes quotas scale from lifetime samples on Free to 40/month on Plus and unlimited on Pro. This is the centre of Spark's 2026 product story.

Airmail is primarily a personal power client. Business builds emphasise privacy and MDM rather than Spark-style shared inbox collaboration. Teams that comment and assign inside email will prefer Spark.

Shared threads, drafts, assignments, and team storage scale with plan. Free allows limited collaborators; Plus/Pro remove ceilings for serious teams. Shared inboxes and read statuses land on higher tiers.

Airmail integrates with 30+ services including Todoist, Things, OmniFocus, Trello, Asana, Evernote, Bear, and Fantastical. Custom actions can chain multiple integrations together for automation-heavy personal workflows.

Spark integrates with popular services such as Todoist, Trello, and Notion, but the library is smaller than Airmail's. It focuses more on built-in features than deep external chains.

AI Composer is available as an optional purchase on some storefronts. It helps draft and rewrite messages, but it is not the centre of Airmail's product. Power users who already write with templates and snippets may never need it.

Spark +AI on Plus and Pro drafts, rewrites, and summarises mail with plan-based history and monthly credits. Free users only see a limited preview. For people who live in long threads, the paid AI assistant is the main reason to leave Free.

Extensive customisation: custom swipe gestures, per-account notification settings, custom actions, multiple layout options, and fine-grained message handling rules. Keyboard shortcuts and plugins extend the surface further.

Clean, opinionated design with moderate customisation. Users can adjust swipe actions and notifications, but the experience is more guided than fully configurable.

Airmail targets Apple platforms: Mac, iPhone, iPad, Apple Watch, and Vision Pro. There is no first-class Android or Windows client. Multi-device Apple users are fine; mixed OS teams are not.

Spark ships on macOS, iOS, Android, and Windows with a consistent account experience. That reach matters for people who switch between a work Windows laptop and a personal Mac, or who share inboxes with Android teammates.

Airmail processes email locally on device for core functionality and does not route mail through its own servers for ordinary reading and sending. Privacy Mode and tracker blocking appeal to security-conscious freelancers.

Spark routes email through Readdle's servers to enable push notifications and Smart Inbox features. Privacy policy updates have improved transparency, but some users still prefer local-only processing.

App Store Pro is $7.99/mo or $49.99/yr. Store text states Airmail Pro is free for subscribers on iOS and for buyers of Airmail 3 since 1 Jan 2019. New users hit freemium limits without Pro. Business is a separate packaging.
