In-Depth Overview
What is Airmail?
Airmail by Bloop is a highly customisable email client for Mac, iPhone, iPad, Apple Watch, and Vision Pro. People still type Airmail 3 because that generation won an Apple Design Award and defined the brand; the Mac App Store app is the continuing product (version 26.x in 2026). It supports Gmail, iCloud, Exchange/Office 365, IMAP, and POP with unified and smart inbox views, snooze, send later, templates, and iCloud sync for settings. Privacy Mode keeps processing local and blocks trackers. Plugins add options such as S/MIME or GPG-oriented workflows. AppleScript automates send and search. Consumer Pro rides App Store subscriptions (commonly $7.99/month or $49.99/year). AI Composer is a separate IAP. Airmail for Business markets a client-only build with MDM and no consumer-style analytics subscription story. Airmail is a programmable personal workstation, not a shared-inbox team product.
What is Spark?
Spark by Readdle is a cross-platform email client built around Smart Inbox prioritisation, clean UX, and team collaboration. Free includes Smart Inbox, unlimited email accounts, smart notifications, essential productivity, and calendar connections. Plus unlocks advanced productivity, Spark +AI, AI Assistant with longer history, meeting notes quotas (40/month), templates, and essential collaboration at $99/year ($8.25/mo equivalent) or $10 monthly. Pro adds unlimited meeting notes, read statuses, advanced team features, HubSpot integration, and Spark CLI triage access at $199/year ($16.58/mo equivalent) or $20 monthly. Workflows and auto-labels/auto-drafts are marked coming soon on the public pricing page in August 2026. Spark's multi-platform reach and AI assistant make it the modern default for people who want less inbox noise without building custom rule engines.
Detailed Feature Comparison
Smart Inbox & AI Sorting
CriticalAirmail 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.
Verdict: Spark leads AI-assisted triage and drafting for most users in 2026.
Team Collaboration
HighAirmail 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.
Verdict: Spark is far ahead for team collaboration. Airmail barely competes in this space.
Third-Party Integrations
HighAirmail 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.
Verdict: Airmail's integration library and custom action chains give power users more flexibility to connect email with their broader tool stack.
AI-Powered Composition
HighAI 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.
Verdict: Spark's paid AI composition is deeper and more integrated than Airmail's optional AI Composer.
Customization & Flexibility
MediumExtensive 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.
Verdict: Airmail offers more knobs for users who want to tailor every part of their email workflow.
Cross-Platform Availability
MediumAirmail 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.
Verdict: Spark wins cross-platform coverage. Airmail is the Apple-centric choice.
Privacy & Data Handling
HighAirmail 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.
Verdict: Airmail's local-first approach wins for people who do not want mail transit through a third-party server.
Licensing & legacy Airmail 3
HighApp 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.
Clear Free/Plus/Pro ladder on sparkmailapp.com/pricing with yearly discounts. No grandfather puzzle: free is free, paid is paid, seven-day trials for paid plans in-app.
Verdict: Spark is simpler to price. Airmail can be cheaper or free for legacy Airmail 3 owners if you verify before comparing list prices.
Who Should Choose Which?
1The Startup Team Lead
Shared inboxes, delegation, and collaborative drafting matter more than custom swipe maps. Spark's team features let a lead assign mail, draft responses together, and leave internal notes. Airmail does not offer that collaboration surface.
2The Privacy-Conscious Freelancer
Sensitive client mail benefits from Airmail's local-first processing. Mail stays on device for core reading and sending, and integrations with task managers keep projects organised without routing everything through a collaboration cloud.
3The Overwhelmed Executive
Hundreds of messages a day need prioritisation. Spark's Smart Inbox surfaces important threads, and paid Spark +AI can summarise long conversations and draft quick replies. That time save usually beats Airmail's deeper settings.
4The Budget-Conscious Student
Spark Free includes Smart Inbox and core productivity at $0. Airmail's free tier is usable, but Spark gives more intelligent sorting without paying. Upgrade later only if AI history or team features become necessary.
5The Power User & Automation Enthusiast
Complex personal workflows (archive, create an OmniFocus task, log a row elsewhere) fit Airmail's custom actions and plugin model. Spark optimises for built-in AI and teams, not deep personal automation chains.
6Long-time Airmail 3 licence holder
If the App Store still treats your Airmail 3 purchase as Pro-unlocked, you already paid. Compare workflow fit against Spark Free without assuming you must buy Airmail Pro again.
Migration Guide
Airmail → Spark
Both clients are IMAP-based, so add the same accounts to Spark with the same credentials. Server-side folders, labels, and history sync automatically. Recreate swipe actions and notification preferences in Spark settings. Airmail custom action chains do not map one-to-one; lean on Spark's built-in AI and rules instead.
Spark → Airmail
Add accounts via IMAP credentials; server-side data syncs automatically. You lose Spark Smart Inbox categorisation and team features. Recreate some sorting with Airmail smart folders and rules. Rebuild third-party integrations through Airmail's action system.
Pro Tips
Because both are IMAP clients, switching is non-destructive to server mail. Run the new client alongside the old one for a week. Export templates and signatures manually. Airmail 3-era users should confirm Pro unlock status in the App Store before paying for Airmail Pro or Spark Plus. Confirm AI add-ons (Spark +AI vs Airmail AI Composer) against real monthly usage, not marketing screenshots.

In Airmail 3 vs Spark for August 2026, Spark remains the better default: usable free tier, Smart Inbox, multi-platform clients, and clear Plus/Pro AI pricing.
