Best for: People juggling multiple personal and work inboxes on Mac and iPhone, Small teams wanting shared inboxes without Superhuman pricing, Users who want AI drafts and meeting notes inside email ## What is Spark? Spark is Readdle’s email client for macOS, Windows, iOS, and Android. In August 2026 it remains actively developed (and is unrelated to Google’s Gemini Spark agent). It ships a generous Free tier plus paid Plus and Pro plans built around Spark +AI, meeting notes, and team collaboration. On Mac it feels like a productivity client: Smart Inbox, unified accounts, Gatekeeper-style prioritisation, calendar, and optional shared inboxes. Pricing verified on sparkmailapp.com/pricing in August 2026: Free ($0) includes Smart Inbox, unlimited accounts, smart notifications, essential productivity tools, and calendar. Plus is $10/user/month or $99/year ($8.25/mo effective) with Spark +AI, AI Assistant, 40 AI Meeting Notes per month, templates, and essential team collaboration. Pro is $20/user/month or $199/year ($16.58/mo effective) with unlimited AI Meeting Notes, read statuses, advanced team collaboration, HubSpot, and Spark CLI triage access. Enterprise is quote-based. Paid plans offer a 7-day trial. Spark +AI is metered: Free gets a limited preview (AI Assistant history capped; 5 lifetime meeting notes). Plus and Pro raise monthly AI credits and meeting-note quotas. Workflows and auto-labels/auto-drafts were still marked Coming Soon on the pricing page mid-2026. On Apple Silicon Macs and macOS Tahoe 26.x, Spark remains a first-class Readdle product alongside Documents and PDF Expert. Competitors to weigh: Mimestream (Gmail-native), Superhuman, Shortwave, Apple Mail, and Outlook. Annual billing is the default recommendation if you already know you want AI notes every month; monthly is fine while you test Plus for a cycle. ## Features - **Smart Inbox.** Smart Inbox sorts mail into personal messages, newsletters, and notifications so the top of the list is what usually needs a reply. You train it by marking importance or moving threads between buckets. It works across connected accounts, so Gmail and Exchange land in the same triage habit. For heavy inboxes this is the Free-tier feature people keep after they try Spark. - **Spark +AI and AI Assistant.** Spark +AI drafts, rewrites, translates, and summarises threads in the composer. The AI Assistant searches mail, attachments, events, and meeting notes with plan-based history depth (about one month on Free preview, one year on Plus, full history on Pro). AI Meeting Notes transcribe and summarise calls: 5 lifetime on Free, 40/month on Plus, unlimited on Pro and Enterprise. Spark +AI stays off by default and draws from a monthly credit quota; add-ons are available when you hit the cap on paid plans. - **Gatekeeper.** Gatekeeper intercepts first-time senders and asks you to accept, block, or categorize them before the message settles into the main inbox. That stops a lot of newsletter and cold-outreach clutter without hunting for unsubscribe links after the fact. Rules can auto-accept corporate domains while still screening personal addresses. Decisions feed later screening so public-facing roles see fewer low-value interruptions. - **Calendar and meeting notes.** Spark syncs Google Calendar, Outlook Calendar, and iCloud into a view that sits next to related mail. You can create events from messages that contain dates. AI meeting notes (quota by plan) attach summaries to events: Plus includes 40 notes per month; Pro is unlimited. Time zone support and focus blocks help distributed teams protect deep work without leaving the mail client. - **Team collaboration.** Shared inboxes, assignments, and internal comments (invisible to external recipients) turn support and sales mail into a light team workflow. Shared drafts keep multiple people on one reply with change history. Templates spread common answers across the org. Mentions ping colleagues inside comments. Pro unlocks the heavier team and HubSpot pieces; Plus covers lighter collaboration with two free collaborators. - **Send Later and email scheduling.** Schedule outgoing mail for a future morning or a recipient’s business hours instead of sending at midnight. Combined with templates, this is how freelancers and consultants keep professional timing while working odd hours. Cancel or edit before the send time if the context changes. It is a core productivity control, not an AI feature, and it works on Free for everyday use. - **Smart Notifications.** Notification rules can filter by sender, content, or time of day. VIP contacts still break through; newsletters stay quiet. Spark respects iOS Focus modes and macOS Do Not Disturb while allowing exceptions you define. Batched digests group non-urgent mail so a phone is not buzzing every marketing blast. On Mac that keeps the dock badge meaningful instead of noisy. ## How to Install Spark on Mac Spark is available on the Mac App Store with automatic updates. It requires macOS 13 Ventura or later and runs on Intel and Apple Silicon Macs. 1. **Open the Mac App Store.** Use the Apple menu or Spotlight to open the App Store. 2. **Search and install Spark.** Search for ‘Spark Mail’, select Spark Mail - AI Email & Inbox by Readdle Technologies Limited, then Get/Install and sign in with your Apple ID if asked. 3. **Launch and connect accounts.** Open Spark from Applications. Grant notifications, contacts, and calendar access you actually want. Sign in with Gmail, Outlook, iCloud, or IMAP and finish Smart Inbox onboarding. ## Pros - Unusually generous free tier with unlimited accounts and Smart Inbox. - Mac, iOS, Android, and Windows clients from Readdle with calendar built in. - Spark +AI writing help and meeting notes with clear per-plan quotas. - Team shared inboxes, comments, and HubSpot on Pro for client-facing groups. - Annual billing cuts Plus and Pro roughly 17% versus month-to-month. ## Cons - Full AI and meeting-note value needs Plus ($99/yr) or Pro ($199/yr). - Auto-labels and auto-drafts workflows still marked Coming Soon mid-2026. - AI credits are metered; heavy users can hit monthly caps. - Not as Gmail-native as Mimestream or as keyboard-centric as Superhuman. ## Spark’s product shape in 2026 Spark is a Readdle email client that grew from an iOS Smart Inbox experiment into a cross-platform product with optional AI and team features. The Free tier is not a crippled demo: unlimited accounts, Smart Inbox, calendar, and core triage are enough for many individuals. Paid plans mainly sell AI depth, meeting notes volume, and collaboration. That packaging matters when you compare seat math with Superhuman (~$30/mo) or Shortwave experiments. Plus at $99/year is the usual upgrade when Free AI previews run out. Pro at $199/year is easier to justify for shared inboxes, read statuses, HubSpot, and unlimited meeting notes than for solo writers who only wanted better drafts. On Mac, install from the App Store build you already trust or follow Readdle’s site guidance, confirm Apple Silicon behaviour on macOS Tahoe 26.x, and re-read sparkmailapp.com/pricing before renewing seats. Published tiers and promotional trials change more often than store screenshots. Prefer the vendor channel you can update cleanly, keep a short rollback plan if you test Pro automation, and try Mimestream or Apple Mail for a week on the same accounts before you migrate rules and signatures. Do not confuse Spark Mail with Google’s Gemini Spark agent. Search results in 2026 mix the names. If you want the email client, look for Readdle. If you want Google’s agentic Mac feature, that is a different download entirely. Re-check meeting-note quotas after each plan change; annual Plus and Pro math is where most people save. For IT admins evaluating seat cost, start every pilot on Free with production accounts for a week. Measure how often people open the AI composer and whether shared inboxes are actually used. Many teams discover they only need Plus for two writers and can leave everyone else on Free Smart Inbox. That mixed-plan reality is allowed by the product shape even if marketing prefers clean Pro upgrades. Privacy-sensitive orgs should still read Readdle’s current security and AI data handling pages before enabling Spark +AI on regulated mailboxes. Turning AI off by default is helpful, but policy has to say who may enable it. Gatekeeper and Smart Inbox alone may be the win without ever buying AI credits. Keyboard-first users should still trial Superhuman if money is no object; Spark’s free tier is the reason most Mac users should try Readdle first. ## FAQ ### How much does Spark Mail cost in 2026?
