Best Shortwave Alternatives in 2026

Shortwave made a strong case for an AI-first Gmail experience. Thread summaries, an AI assistant that drafts replies, and a clean modern interface helped it stand out from the older “smart inbox” generation. By 2026, though, more users are running into the same limits: Shortwave is Gmail only, the AI features sit on top of a fairly traditional inbox, and pricing has crept up for power users who want full AI access.

The good news is the AI email category finally has serious competition. Some apps now triage every message into clear buckets before you open the inbox. Others bring AI alongside end-to-end encryption. A few stay free and keep things simple. Below are the best Shortwave alternatives in 2026, compared on platform support, pricing, what each app does well, and where each one falls short.

Key takeaways

• Dove is the closest match to Shortwave for people who want AI to take real work off their plate. It sorts every email into Focus, Noise, and Done before you open the inbox, on top of any account, not just Gmail.

• Canary Mail is the best pick for privacy-first users who want a polished modern client with optional AI and PGP encryption built in.

• Superhuman is still the speed benchmark if you want a keyboard-driven Gmail and Outlook experience and price is not a constraint.

• Apple Mail and Spike are both viable free options if you mostly want a calmer inbox without a subscription.

• Mimestream is the quiet pick for native macOS and Gmail. Hey is the most opinionated rebuild of email if you are open to a new address.

What Shortwave does well, and why people still look for alternatives

Shortwave’s pitch is honest. It is built around Gmail, leans hard into AI summaries and drafting, and feels noticeably faster than the default Gmail web UI. For Gmail-only users who want AI inside a familiar inbox shape, it works.

The reasons people start looking for alternatives are predictable.

• It is Gmail only. If you also have Outlook, iCloud, Yahoo, or a custom IMAP account, you end up running two apps.

• The AI sits on top of a standard inbox. Threads still pile up, you still scroll, you still decide what matters before AI gets involved.

• Pricing for full AI access has moved up. Many users compare it to other AI clients and reassess.

• Mobile parity is good but not perfect. Power users still feel the gap between desktop and phone.

• Privacy-sensitive users want more than “AI on Gmail.” They want encryption, on-device processing, or both.

None of this is a knock on Shortwave. It is just the shape of the market in 2026. The alternatives below each solve one of these gaps better than Shortwave does.

Best Shortwave alternatives at a glance

The rest of this guide walks through each app in detail. Dove and Canary Mail come first because they are the two we think Shortwave users will weigh hardest, AI-native triage and privacy-first AI. The other six follow.

1. Dove, best for AI-native triage across any account

Dove is an AI-native email app from Cartasec, the Singapore-based team behind Canary Mail. Where Shortwave layers AI on top of Gmail, Dove rebuilds the inbox around AI from the start. Every incoming message is sorted automatically into one of three buckets, Focus for the things that actually need you, Noise for newsletters, receipts, and likely threats, and Done for messages that are already handled. You open Dove and see a short list of what matters, not a wall of unread.

The two features that pull people across from Shortwave are Wingman and AI Assist. Wingman is thread intelligence that surfaces hidden risks, missed asks, and the right next step inside long threads, the kind of context a summary alone tends to miss. AI Assist drafts replies in your tone and handles common tasks like scheduling, follow-ups, and unsubscribes. Both run across all your accounts, not just Gmail.

Dove works as a client on top of Gmail, Outlook, iCloud, and any IMAP account. You do not need a new email address. The AI does not depend on which provider you use.

Platform support. Web, iOS, Android, macOS, Windows.

Pricing. Free plan with up to 10 AI actions per day. Paid plan at $20 per month with full AI features, 7-day free trial.

What Dove does well

• Sorts every message into Focus, Noise, and Done before you open the inbox

• Wingman thread intelligence catches risks and asks buried in long threads

• AI Assist drafts replies, handles scheduling, follow-ups, and unsubscribes in your tone

• Works across Gmail, Outlook, iCloud, IMAP, and most other providers

• Native apps on Web, iOS, Android, macOS, and Windows, no provider lock-in

What Dove does poorly

• Not an end-to-end encrypted email provider, it works as a client on existing accounts

• No PGP support, pair with Canary Mail if you need encrypted messaging

• Less keyboard-shortcut focused than Superhuman, the speed angle is “less to read”, not “type faster”

• Free plan caps AI usage at 10 actions per day, heavy users will quickly outgrow it

2. Canary Mail, best for privacy-first power users who want optional AI

Canary Mail is the privacy-first sibling to Dove, built by the same team. It is a polished, full-featured email client with PGP end-to-end encryption, SecureSend for encrypted messages to non-PGP recipients, and optional AI Copilot that runs on-device. Where Shortwave is cloud-AI on Gmail, Canary Mail is privacy-first email with optional AI that never leaves your device.

If you want a modern inbox with proper encryption baked in, this is the cleanest option. SecureSend is HIPAA-compliant, which makes Canary Mail one of the few consumer clients suitable for therapists, lawyers, healthcare workers, and anyone with regulated communication needs. The AI Copilot is an add-on, not the foundation, so privacy-conscious users can switch it off entirely without losing core features.

Like Dove, Canary Mail is a client, not a provider. It works with Gmail, Outlook, iCloud, IMAP, and Exchange.

Platform support. macOS, iOS, Android, Windows.

Pricing. Free tier with core email features. Growth plan around $36 per year. Pro+ around $100 per year with SecureSend and advanced security. Lifetime purchase options also available.

What Canary Mail does well

• PGP end-to-end encryption built into a modern, polished interface

• SecureSend, HIPAA-compliant encrypted messages to recipients without PGP

• Optional AI Copilot runs on-device, no email content leaves your machine

• Power-user features, read receipts, snooze, pin, bulk cleaner, templates, one-click unsubscribe

• Works with existing Gmail, Outlook, iCloud, IMAP, and Exchange accounts

What Canary Mail does poorly

• No web client, you have to install the native app

• No Linux support

• Advanced security features sit behind the Pro+ tier

• The AI Copilot is intentionally optional, so it is less ambient than Dove or Shortwave

If you want both AI triage and PGP, the practical setup in 2026 is Dove for triage on one account and Canary Mail for the encrypted threads that matter. Read Canary Mail’s privacy positioning for the full picture.

3. Superhuman, best for keyboard-driven speed if price is not a constraint

Superhuman was the original “premium email” pitch and is still the speed benchmark for Gmail and Outlook users who type faster than they click. The 2025 refresh brought AI features and a noticeably better mobile app, but the core appeal is unchanged, a keyboard-driven interface that turns triage into a rhythm.

In 2026, Superhuman feels like a polished cousin to Shortwave. Both lean on AI, both target power users, both want you to clear the inbox quickly. The two differences are price and account scope. Superhuman is more expensive, and it now supports Outlook in addition to Gmail.

Platform support. macOS, Windows, iOS, Android, Web.

Pricing. No free tier. From around $30 per month.

What Superhuman does well

• Best-in-class keyboard shortcuts and triage flow

• Strong native apps on macOS, Windows, iOS, and Android

• AI features and reminders integrated into the keyboard workflow

• Gmail and Outlook both supported

What Superhuman does poorly

• No free tier, the price is a real commitment

• Only Gmail and Outlook accounts, no iCloud, no plain IMAP

• Speed depends on you learning the shortcuts, the value is lower for casual users

• AI is helpful but does not change the inbox shape the way Dove does

See how Dove compares to Superhuman in our Superhuman alternatives roundup.

4. Spark Mail, best for cross-platform smart inbox and team drafts

Spark Mail was the “easy recommendation” for years because it gave you a clean smart inbox on every major platform. Spark 3 raised prices and moved more features behind paywalls, but it is still one of the most reliable cross-platform email clients you can pick.

Spark’s smart inbox groups newsletters, transactions, and personal messages on its own. Shared drafts and “delegate this email” features make it a quiet pick for small teams that want lightweight collaboration without buying a help desk.

Platform support. macOS, iOS, Android, Windows.

Pricing. Limited free tier. Premium around $7.99 per month, with discounts on annual plans.

What Spark does well

• Reliable smart inbox grouping across all major platforms

• Shared drafts and email delegation for small teams

• Calendar, snooze, send later, follow-up reminders built in

• Mature mobile apps with strong gesture support

What Spark does poorly

• The free tier is now noticeably more limited than in earlier versions

• Some account-level features are tied to a Spark identity, not your provider

• AI features are present but feel layered on top, not core

• No PGP, no on-device AI, weaker for privacy-sensitive users

See our Spark Mail alternatives roundup for the longer comparison.

5. Mimestream, best for native macOS plus Gmail

Mimestream is a love letter to native macOS development and Gmail. It uses the Gmail API directly so labels, search, and filters behave the way they do in Gmail itself, while wrapping them in a fast, polished AppKit interface. There is no Electron tax, no slow web view.

It is not an AI app, and it is not trying to be. For Gmail users who want a native Mac email client first, with smart inbox features second, Mimestream is the cleanest pick.

Platform support. macOS, iOS.

Pricing. Free trial. Subscription around $49.99 per year.

What Mimestream does well

• Native macOS performance, no Electron, no web wrapper

• True Gmail API integration, labels, search, and filters behave as expected

• Excellent multi-account support for Gmail and Google Workspace

• iOS app continues the same native experience

What Mimestream does poorly

• Gmail only, no Outlook, no iCloud, no IMAP

• macOS and iOS only, nothing for Windows, Android, or web

• No native AI features yet, you bring your own assistant

• Less useful if your email life is not built around Gmail

6. Apple Mail, best free baseline for Apple users

Apple Mail is not exciting, but it is honest. It is pre-installed on every Apple device, free with your iCloud account, and the privacy features quietly do useful work. Mail Privacy Protection blocks tracking pixels and hides your IP from senders by default. Hide My Email creates throwaway addresses you can hand out without revealing your real one.

For users who picked Shortwave mainly because they wanted “a nicer email app”, Apple Mail in 2026 is genuinely nicer than it used to be, and it costs nothing extra.

Platform support. macOS, iOS.

Pricing. Free with any Apple device. iCloud+ from $0.99 per month adds Hide My Email and custom domain support.

What Apple Mail does well

• Free, pre-installed, zero setup

• Mail Privacy Protection blocks tracking pixels and hides your IP by default

• Hide My Email generates disposable relay addresses

• Deep OS integration with Focus modes, notifications, and Siri

What Apple Mail does poorly

• Apple ecosystem only, no Windows, Android, or proper web client

• No real AI triage, no Focus and Noise sorting like Dove

• No PGP support without third-party plugins

• Smart features are still much lighter than what AI-native clients ship

7. Spike, best for chat-style email

Spike treats email like chat. Your conversations show up as ongoing threads with avatars and bubbles instead of formal email blocks. Notes, tasks, video calls, and group chats live alongside email in the same app. If you have ever wished email felt more like Slack or iMessage, Spike is the closest you can get without leaving email behind entirely.

The chat metaphor is polarizing, some users love it, others find it too informal for work. Spike is at its best for small teams and individuals who already use email as a primary communication channel and want a calmer interface around it.

Platform support. Web, macOS, Windows, iOS, Android.

Pricing. Free tier. Pro plans from around $6 per user per month.

What Spike does well

• Conversational, chat-like email layout

• Built-in notes, tasks, video calls, and group chats

• Cross-platform with strong feature parity

• Priority Inbox separates important messages from low-signal mail

What Spike does poorly

• The chat metaphor is divisive, formal users find it odd

• Heavier app footprint than a pure email client

• AI features exist but are less central than in Dove or Shortwave

• Some advanced features require team plans

8. Hey, best opinionated rebuild of email

Hey, from the team behind Basecamp, is the most opinionated alternative on this list. It rebuilds email from the ground up. New senders go through a Screener, newsletters land in the Feed, and receipts go to the Paper Trail. The Imbox is reserved for the people and threads you actually said yes to.

If your problem with Shortwave is “AI cannot fix how broken my inbox already is”, Hey is the most interesting bet, because Hey decides the inbox should not look like a list of timestamps at all.

Platform support. Web, macOS, Windows, iOS, Android.

Pricing. Personal from $99 per year. Hey for Work and Hey for Domains have separate plans.

What Hey does well

• The strongest opinion in email since Gmail itself, Screener, Feed, and Paper Trail are a real rethink

• Bundles tracking blocking, send later, snooze, and rich notes natively

• Consistent experience across Web, macOS, Windows, iOS, and Android

• One annual price, no upsells

What Hey does poorly

• Full experience needs a new hey.com address, importing existing mail is limited

• Strong opinions cut both ways, you either accept the model or fight it

• AI features are deliberately light, this is not an AI-first client

• No PGP support, no on-device AI

How to choose the right Shortwave alternative

A short shortcut. If Shortwave’s AI angle is what hooked you, look at Dove or Canary Mail first. Dove changes the inbox shape, sorting into Focus, Noise, and Done. Canary Mail keeps the AI optional and adds real encryption. If the AI angle is secondary and you mostly wanted “a faster Gmail experience”, Superhuman, Mimestream, and Apple Mail are all stronger picks than Shortwave on speed and price respectively.

FAQ

What is the best Shortwave alternative in 2026?

Dove is the best Shortwave alternative for users who want AI to do real work on the inbox, not just summarize threads. Dove sorts every email into Focus, Noise, and Done automatically, drafts replies in your tone, and works across Gmail, Outlook, iCloud, and IMAP, not just Gmail. Canary Mail is the best alternative if you want privacy-first email with optional on-device AI and PGP encryption built in.

Is Shortwave only for Gmail?

Yes. Shortwave is built on the Gmail API and only supports Gmail and Google Workspace accounts. If you also use Outlook, iCloud, Yahoo, or a custom IMAP account, you have to run a second app. Dove, Canary Mail, Spark, and Superhuman all support multiple providers in a single client, which is one of the most common reasons users move off Shortwave.

How does Dove compare to Shortwave on AI features?

Dove and Shortwave both lean on AI, but they apply it differently. Shortwave keeps a standard inbox and adds AI on top, summaries, search, and an assistant for drafting. Dove rebuilds the inbox around AI from the start. Every message is sorted into Focus, Noise, or Done before you open the app, and Wingman reads long threads for hidden risks and asks. The practical difference is that Dove changes what you see, not just what you can do once you see it.

Which Shortwave alternative has the strongest privacy story?

Canary Mail. It supports PGP end-to-end encryption, ships SecureSend for encrypted messages to recipients without PGP, and runs its AI Copilot on-device so email content never leaves your machine. If your concern is encryption rather than triage, Canary Mail is the clearest pick. If you want both, the practical setup is Dove for AI triage and Canary Mail for encrypted threads.

Are any of the alternatives free?

Yes. Apple Mail is free with any Apple device. Spike has a free tier. Dove offers a free plan with up to 10 AI actions per day, which is enough for light triage and replies. Canary Mail has a free tier for core email features, with paid tiers for SecureSend and advanced security. Superhuman and Hey have no free tier.

Do I need a new email address to switch from Shortwave?

For most options, no. Dove, Canary Mail, Superhuman, Spark, Mimestream, Apple Mail, and Spike all work as clients on top of your existing Gmail, Outlook, iCloud, or IMAP account. The only exception is Hey, which offers its full experience on a new hey.com address. If you want to keep your current address and just change how you read and triage email, any of the others will work.

What does Shortwave do better than its alternatives?

Shortwave is still strong for Gmail-only users who want AI inside a familiar inbox layout, without changing the inbox shape. Thread summaries and the assistant are good, and the app is fast. If you only have Gmail accounts, do not need PGP, and prefer that AI assists rather than triages, Shortwave is a reasonable choice. The alternatives in this guide each beat Shortwave on one specific axis, account support, triage, privacy, price, or platform reach.

Your inbox, your rules

Shortwave got the AI email category moving. The market followed. By 2026 there are stronger picks for almost every situation. Dove, if you want AI that sorts the inbox before you read it. Canary Mail, if you want optional AI and real privacy. Superhuman, if you want speed and shortcuts. Spark, Mimestream, Apple Mail, Spike, and Hey, if you want something specific that Shortwave does not do well.

The one approach that does not work is staying on a tool that no longer fits how you work. Your inbox is not going to fix itself.
