Notion confirmed that Notion Mail is shutting down in 2026, with the Gmail messages stored on its servers safe and the iOS app set to disappear from the App Store after the wind-down. If you trusted it with your inbox, the migration window is real and worth using deliberately. These seven mobile email apps for Android and iOS cover everything Notion Mail did and a few things it never managed, from end-to-end encrypted accounts to AI summaries that actually save time.
We tested each on a 50,000-message Gmail account and a separate IMAP work account, checking sync time on cold launch, the quality of automated filtering, paid-tier value, and the gap between Android and iOS feature parity. These are Notion Mail alternatives we would actually move our own mail into.

Why Notion Mail is going away
Notion told users the email product was not pulling its weight inside Notion’s broader workspace bet, and the move to focus on Notion AI agents meant pulling resources back to the core app. Three friction points showed up consistently in the Reddit and Twitter threads after the announcement.
- iOS-only kept the audience small. Notion Mail never shipped on Android, leaving half the market off the table.
- It was a Gmail front-end, not a real email client. Notion Mail did not handle IMAP, Outlook, or anything other than Google accounts.
- The AI promise outpaced the delivery. Auto-categorization and smart replies improved through the run but never matched Spark or Superhuman.
- Pricing was unclear. The path from free to paid AI features felt like a moving target.
Which app should you pick?
- Gmail if your Notion Mail address was Gmail to begin with and you want the lightest move.
- Microsoft Outlook if you mix Outlook and Gmail and want both in one app.
- Proton Mail if privacy matters more than features.
- Spark Mail if Notion Mail’s calm-inbox promise is what you want done right.
- Edison Mail if you want a free privacy-leaning aggregator.
- Spike if you want email that reads like chat.
- Fastmail if you are ready to switch addresses for the long term.
1. Gmail -- the lightest Notion Mail exit if your account is already Gmail
Most Notion Mail users had it pointed at a Gmail account anyway. Gmail on mobile is the simplest landing spot, and the 2026 redesign added smart summarization for long threads and a clean three-pane mode on tablets. Sync time on a 50,000-message account is under a minute on a mid-range Android.
Where it falls short: Promotions tab fills back up. Smart Compose can be aggressive on professional email.
Pricing:
- Free with personal Gmail.
- Workspace from $6/user/month for custom domains.
- vs Notion Mail: better Android integration, weaker AI inbox triage out of the box.
Migrating from Notion Mail: No real migration needed. Notion Mail used your existing Gmail account, so the mail is already in Gmail. Uninstall Notion Mail when you are settled.
Bottom line: Pick Gmail if you only used Notion Mail as a Gmail skin and want the simplest exit.
2. Microsoft Outlook -- when calendar lives next to email
Microsoft Outlook mobile combines email, calendar, and contacts in one app and handles both Outlook.com and Gmail accounts natively. Focused Inbox does the auto-triage Notion Mail’s “AI inbox” pitched. The 2026 redesign added Copilot summaries inside the inbox.
Where it falls short: Free tier shows ads in Other inbox. Some Gmail labels do not round-trip cleanly to Outlook’s folder model.
Pricing:
- Free with limits.
- Microsoft 365 Personal $6.99/month removes ads and adds 1TB of OneDrive.
- vs Notion Mail: tighter calendar integration, deeper enterprise feature surface.
Migrating from Notion Mail: Add your Gmail account to Outlook and let it sync. Old Notion Mail filters need to be rebuilt as Outlook rules.
Bottom line: Pick Outlook if calendar parity with email matters as much as email itself.
3. Proton Mail -- the privacy upgrade Notion Mail did not offer
Proton Mail is the encrypted-by-default option from the team behind ProtonVPN. Mail is encrypted at rest and end-to-end between Proton accounts; aliases (hide-my-email) ship in the free tier. The mobile app on Android has caught up to the web in 2026.
Where it falls short: Free tier capped at 1GB. Search on free tier is body-restricted (paid plans give full search).
Pricing:
- Free: 1GB, one address.
- Mail Plus $3.99/month: 15GB, custom domain, unlimited folders.
- vs Notion Mail: zero-access encryption, far stronger privacy posture, no AI.
Migrating from Notion Mail: Import via Proton’s Easy Switch tool; it pulls your Gmail mail into Proton through OAuth. Set up forwarding from Gmail so future messages land in Proton.
Bottom line: Pick Proton Mail if Notion Mail’s loose handle on privacy bothered you.
4. Spark Mail -- the calm-inbox promise done well
Spark Mail from Readdle is the closest spiritual cousin to what Notion Mail tried to be: an inbox that auto-groups senders, separates newsletters and notifications from people you actually correspond with, and surfaces real work. The 2026 update added AI thread summaries that match Notion Mail’s pitch.
Where it falls short: Premium tier is required for advanced filters and shared inboxes. Some users dislike that Readdle proxies mail through their servers for processing.
Pricing:
- Free: smart inbox, basic filters, all accounts.
- Premium $4.99/month: AI summaries, gatekeeper, shared inboxes.
- vs Notion Mail: matches the calm-inbox aim, ships on both Android and iOS.
Migrating from Notion Mail: Add your Gmail account to Spark via OAuth. Spark’s Smart Inbox does the auto-triage Notion Mail’s AI promised.
Bottom line: Pick Spark Mail if you want the Notion Mail promise but actually delivered.
5. Edison Mail -- the free privacy-leaning aggregator
Edison Mail aggregates multiple accounts, blocks read-receipt trackers automatically, and runs strong unsubscribe and bulk-delete tools. It is the most generous free tier on this list. Edison’s own paid email service (OnMail) is separate.
Where it falls short: The “AI” assistant is thin compared to Spark. Calendar integration is basic.
Pricing:
- Free: full feature set on three accounts.
- OnMail $4.99/month: dedicated Edison-hosted address.
- vs Notion Mail: lighter on AI, heavier on inbox hygiene tools.
Migrating from Notion Mail: Add your Gmail account, run the One-Tap Unsubscribe sweep, and let the tracker blocker handle the receipt of new mail.
Bottom line: Pick Edison Mail if you want a strong free pick with tracker blocking.
6. Spike -- email that reads like chat
Spike treats every conversation as a chat thread, collapses signatures and quoted reply chains, and adds Notes, Tasks, and Collaborative Pages. The 2026 release added an AI Magic Reply feature and stronger team workspaces. Closest in feel to Notion Mail’s “email but make it modern” angle.
Where it falls short: Some recipients see Spike’s chat-style threading as unusual on their side. Free plan caps team features.
Pricing:
- Free: solo accounts.
- Pro $5/month per user: shared inboxes, AI features, Collaborative Pages.
- vs Notion Mail: closest in tone, broader feature set, real cross-platform.
Migrating from Notion Mail: Sign in with your Gmail, accept the calendar permission, and the chat-style threading kicks in immediately.
Bottom line: Pick Spike if Notion Mail’s modern tone was the draw.
7. Fastmail -- the power-user IMAP move
Fastmail is the address-change option. Hosted in Australia, no advertising business model, fast IMAP, Sieve filters, and per-app passwords. Masked email addresses ship for spam-blocking. Fastmail is the alternative for people who want their email to outlive the next big-tech consolidation.
Where it falls short: Requires changing your address (or a custom domain). The mobile app is minimal compared to Spark and Outlook.
Pricing:
- 30-day free trial.
- Standard $5/month: 30GB, custom domain, masked email.
- vs Notion Mail: stronger underlying email plumbing, far less product surface.
Migrating from Notion Mail: Add your Gmail to Fastmail as an IMAP import, set Gmail to forward to your new Fastmail address, and update key services with the new address over a month.
Bottom line: Pick Fastmail if you are ready to leave the free-mail-as-business model entirely.
FAQ
Will my Notion Mail messages be deleted? No. Notion confirmed your Gmail messages remain on Google’s servers. Notion Mail was a client on top of your Gmail account, not its own mail store.
What happens to my Notion Mail filters? Filters built inside Notion Mail go away with the app. Filters configured on the Gmail side persist.
Is Spark Mail safe to give Gmail access to? Spark proxies mail through Readdle’s servers to power its smart features. If that bothers you, Proton Mail or Fastmail are better fits.
Which Notion Mail alternative has the best free plan? Edison Mail is the most generous; Gmail itself is free if you only need one Gmail account.
Can I keep using Notion Mail until the shutdown? Yes, but starting the migration earlier reduces the pressure as the date approaches.
