Shortwave Email Review: Is the AI Gmail Client Worth It?

Key Takeaways

• Shortwave is an AI email client that works natively only with Gmail and Google Workspace. Outlook, Yahoo and other accounts can be added only by first connecting them to a Gmail account.
• Its AI assistant is the main reason to use it: it searches, writes, schedules and can even tidy your inbox from a chat. Give its work a quick check before you confirm.
• A Free plan exists, but it adds a "Sent with Shortwave" signature, limits search to 90 days and limits AI searches. Paid plans cost $18 to $120 per seat per month.
• New in 2026: AI tiers powered by Anthropic's Claude models and automations through Tasklet, Shortwave's sister product.
• If you want to clean the mailbox you already have, on any mail provider, without switching apps, Clean Email is the better fit. You can now also run it from Claude, ChatGPT or Codex.

What Is Shortwave?

Shortwave is an AI-powered email client for Gmail and Google Workspace. It replaces the Gmail app on the web, Mac, Windows, iPhone and Android, but your mail stays in your Gmail account.

The email app has strong ideas about how you should manage your inbox and isn't shy about promoting them. At the heart of this philosophy is the "Shortwave Method," a structured approach to achieving inbox zero that transforms your inbox from a chaotic mess into an organized workspace.

The Shortwave AI email system wants you to approach your inbox the same way a rescue worker approaches a car accident (they use a different metaphor, but I prefer this one): assess everything quickly, handle immediate priorities, and create a clear plan for more complex cases.

This "email triage" methodology breaks down all incoming messages into three categories:

1. Non-actionable items: Newsletters, notifications, and FYI emails that require no response. These should be archived or deleted immediately to reduce clutter.
2. Quick tasks: Messages you can handle in under two minutes, like confirming a meeting time or sharing a requested document. These should be dealt with on the spot.
3. Longer tasks: Emails that need more substantial time and attention, such as detailed proposals or complex questions. These get converted into tracked tasks for later focus.

The secret sauce of the Shortwave Method is its insistence that you complete this triage process before writing detailed responses or doing complex tasks.

In practice, the Shortwave email app implements this system through an intelligent combination of AI assistance and smart organizational tools. When you first open the app, it encourages you to process your entire inbox in a single pass, making quick decisions about each message.

The app's AI features (more about them soon) help streamline this process by grouping similar messages together and suggesting quick actions. The good news is that even if you don't fully embrace the methodology, many of the app's features can still be valuable for general inbox organization.

Inside the Shortwave Email Experience

The Shortwave email app offers apps for all major platforms—iOS, Android, Mac, and Windows, plus a web app. While I've primarily used the Mac version for this review, I've also spent time with the mobile apps, which have earned impressive ratings (4.7 stars on iOS and 4.5 stars on Android) for their thoughtful design and functionality.

Right after you sign up, Shortwave asks how you want to split your inbox: Single Inbox, Important & Other, or Classic Gmail. Your choice changes how the inbox looks, and you can change it later in Settings.

I chose Classic Gmail, so Shortwave set up the familiar Gmail tabs as splits automatically. The desktop layout has three parts: the AI assistant panel on the left, your message list in the middle, and your calendar on the right.

The mobile interface manages to condense this layout into a format that works smoothly on smaller screens.

My basic email management routine in Shortwave starts with familiar actions like move, archive, and delete. There's no menu next to each message in the inbox list, though. To see more options, open an email and use the three-dot menu at the top. That's where things get interesting.

For example, the three-dot menu has "Bundle threads like this," which automatically groups similar emails together. I like this feature for managing newsletters and promotional content—instead of dealing with dozens of individual marketing emails, they get neatly bundled into manageable groups.

Also, one feature that initially excited me was the unsubscribe option. You'll find it in the same three-dot menu of an opened email.

You can also select several emails in the inbox and unsubscribe from all of them at once.

Still, I found that some obvious subscription emails don't show the unsubscribe option at all—usually because the sender didn't include proper unsubscribe headers.

For emails that require action but can't be handled immediately, Shortwave offers a to-do system. You can add any email to your todos with just a click, and the implementation is quite flexible.

Want to organize related tasks together? The "Move to another todo" feature lets you group similar items. Once you've completed a task, marking it as "Done" removes it from your active todos while keeping it accessible in your archive.

If many of your emails are really tasks—requests, approvals, things to reply to later—this setup lets you use Shortwave as a task manager for your inbox. Your to-dos live right next to your mail, so you don't need a separate to-do app.

One catch: when your inbox doubles as a to-do list, it fills up fast. Newsletters and notifications pile up around your tasks, take up storage, and give the AI more to search through. To keep your storage free and your AI searches focused on what matters, I'd recommend connecting your inbox to the email cleaning app Clean Email that I mention later in this review.

There's also the snooze feature, which can make a message reappear at a more convenient time. You can quickly pick from a handful of suggested snooze options (tomorrow, this weekend, next week, and so on), or you can easily enter a custom snooze time just by typing something like "4 hours."

Perhaps the most powerful organizational feature is Shortwave's implementation of filters, which they call "Splits." They appear as tabs at the top of your inbox, and the ones you picked during setup are created for you automatically.

You can manage them in Settings under "Inbox setup." The default splits are Important, Promotions, Social, Updates, Other, and Todos. You can also add your own split based on labels, contacts, or any search query.

📌 What really impressed me was the attention paid to business users with special notification splits, which can automatically organize emails based on department (Engineering, Design, Product, Sales) or even specific tools (Asana, GitHub, Salesforce).

Team plans also add AI filters: rules you write in plain English, such as "label every invoice as Finance," that label, star or archive new mail for you. Business includes 3 AI filters, Premier 10, and Max 50.

Shortwave AI Features in 2026

You might have noticed that I've yet to talk about Shortwave's AI email management features, even though they're front and center in most of their marketing materials. That's intentional—I wanted to give these capabilities their own dedicated section to really examine if the Shortwave AI email features live up to the promises.

The quickest way to see the AI at work is the banner at the top of the inbox: "Want the Shortwave AI to organize your inbox?" When I clicked "Lets do it!", the assistant searched my Primary split, picked out promotional emails and newsletters, and asked me to confirm before it marked them as done. Nothing changed until I clicked "Mark done."

📌 On the Free plan, you'll see "Search query limited by plan" under the assistant's searches. It still works, but it looks through fewer threads than on paid plans.

The Shortwave app includes several other AI-powered features that streamline your email workflow. While composing emails, the app suggests contextual phrases and even complete sentences based on your writing history. It's meant to help you write faster by predicting what you might say next, including real links and facts from your email history.

📌 In practice, many suggestions were spot-on. A few sounded more formal than I would write, so I still read them before sending.

The real star of the show is the Shortwave AI assistant, now marketed as the Shortwave Agent. It lives in a panel on the left side of the inbox, so it's always one click away, and Shortwave introduces it as your "AI executive assistant" during setup. You can think of it as a ChatGPT that's built directly into your email client—but with full access to your email history and calendar.

The assistant can handle a wide range of tasks, from the mundane to the complex:

• Need to schedule a meeting? Just tell it something like "set up a coffee chat with Sarah next Tuesday morning," and it will check your calendar, draft an email with suggested times, and create the calendar event.
• Instead of remembering complex search operators, you can simply ask questions like "what was the address of that restaurant Mike suggested last month?" or "find all the feedback emails about the new design."
• Ask it to "find urgent emails," and it searches your inbox, explains what it found, and points out the messages worth your attention.

You can also personalize it. In Settings under "AI Personalization," you can save your own prompts and use Memory so the assistant remembers your preferences.

What's new in 2026

• Claude models. Since February 2026, Shortwave's AI runs on Anthropic's Claude models: Haiku 4.5 on the Free plan, Sonnet 4.6 on Pro, Business and Premier, and Opus 4.6 on Max.
• Bigger AI search on higher plans. One AI search can read up to 15 threads on Free, 50 on Pro and Business, 100 on Premier, and 150 on Max.
• Tasklet automations. Since January 2026, Shortwave connects to Tasklet, its sister product, under "AI Agents" in Settings. Tasklet can draft replies and organize threads automatically when a trigger fires, and it connects to 3,000+ apps. It is a separate product.

• Integrations. In Settings under "AI Integrations," you can connect the assistant to Google Calendar, a web browser, Notion, Slack, Asana, Linear, Zapier, and HubSpot, or add a custom integration.

In my testing, the AI took a lot of routine work off my plate. It found old emails from a plain-language question, drafted replies that needed only small edits, and cleared out promotions with a couple of clicks.

The best way to use it is as a smart first draft. I still read every draft and checked each calendar invite before I confirmed it, and Shortwave makes that easy because it asks before it acts.

Natural-language search and the "organize my inbox" suggestions were the features I came back to most.

📌 Keep in mind that Gmail now has its own AI. Gemini in Gmail gives everyone free thread summaries, Help Me Write, and suggested replies. With a paid Google AI or Workspace plan, you can also chat with Gemini in a side panel and ask it to archive, delete, label, or move emails, and it asks you to confirm each time.

Shortwave vs Gemini in Gmail: What's Actually Different?

Both let you chat with AI about your email in plain English, so the choice comes down to a few real differences:

If you mainly want AI to help you read and write email, Gemini in Gmail may be enough. If you want to run your inbox like a to-do list, with bundles, custom splits, AI filters for new mail, or team features, Shortwave is worth the switch.

AI Features and the Issue of Data Privacy

When any email tool introduces AI capabilities, it immediately raises legitimate privacy concerns. After all, we're talking about giving an AI system access to potentially sensitive personal and business communications. In the case of the Shortwave email app, these concerns are particularly relevant given how deeply AI is integrated into every aspect of the experience.

📌 The good news is that Shortwave explicitly states that your email content is never used to train third-party AI models.

The system uses an approach called Retrieval Augmented Generation (RAG). When you interact with the AI assistant, it follows a four-step process:

1. Tool Selection: The AI first determines what types of data it needs to answer your query.
2. Data Retrieval: It gathers relevant information from your email history and other sources.
3. Answer Generation: The AI creates a response using the collected context.
4. Post-Processing: The system formats the response and adds relevant citations.

According to its security page, Shortwave runs most of its AI work on open-source models on hardware it controls. Your data is stored in Google Cloud, and only a short list of sub-processors—OpenAI, Anthropic, and Pinecone—receive the data they need for the AI features. Data is encrypted in transit (TLS 1.2+) and at rest (AES256). Even so, cloud processing could be a deal-breaker for businesses in regulated industries.

Shortwave has also passed CASA Tier 2, the security assessment Google requires from apps that access Gmail data.

However, for most regular users, this won't be a significant concern. After all, Shortwave only works with Gmail accounts, and Gmail itself is a cloud-based service where your emails are already stored and processed on Google's servers.

Shortwave Pricing in 2026

Shortwave has two plans for individuals and three for teams. Every paid plan starts with a 14-day free trial. Prices are per seat per month, as listed on Shortwave's pricing page in October 2026.

The Free plan is fine for a test drive, but the forced signature and 90-day search make it hard to use long term. For most people, Pro at $18 a month is the real starting price.

Team plans add shared threads, team comments, assignees and shared labels. One catch: AI filters, AI integrations and attachment analysis are only on team plans. Pro does not include them, and I fount that on Reddit this is the most common complaint from paying individual users.

Shortwave Pros and Cons

Shortwave vs Clean Email: Which One Do You Need?

Shortwave and Clean Email solve different problems. Shortwave replaces the app you read and write email in, and it works only with Gmail. Clean Email cleans the mailbox you already have—Gmail, Outlook, Yahoo, iCloud, AOL, or any other mail provider—and works next to any email app, including Shortwave.

Clean your inbox from Claude, ChatGPT, or Codex

Your AI assistant can work with email. With Clean Email, it can clean it. Connect Clean Email to Claude, ChatGPT, or Codex, then ask what's cluttering your inbox. Clean Email finds the clutter, your assistant sums it up for you, and you decide what gets cleaned.

That covers bulk deleting, unsubscribing from many senders at once (including blocking the ones that ignore unsubscribe requests), and rules that keep your inbox clean, in every mailbox you've connected—not only Gmail. Big jobs keep running in the background until they're finished, so you can close the chat.

Unlike Shortwave's AI, which lives inside one Gmail app, this works with the AI assistant you already use. It's available to all Clean Email users, including the free trial (clean up to 1,000 emails). In Claude, you add Clean Email as a connector; in ChatGPT and Codex, as a plugin. See how to connect Clean Email to your AI assistant.

Which one should you pick?

• Pick Shortwave if you want an AI-first Gmail app that writes, searches and schedules for you, or your team shares email threads.
• Pick Clean Email if you want a clean inbox, not a new app. A new email app doesn't empty your mailbox: the newsletters keep coming, and old mail still uses your storage. Clean Email deletes old mail in bulk and unsubscribes you from many senders at once, in the app you already use, on any mail provider. You can do it in the Clean Email app or just ask your AI assistant. Try it free on your first 1,000 emails.
• Already on Shortwave? Shortwave is built for working with today's email, not for clearing years of old mail. Use Clean Email for that bulk cleanup. Both work with the same Gmail account, so the result shows up in Shortwave right away.

Shortwave Alternatives

If you use Outlook or iCloud next to Gmail, look at Spark: it's the free alternative that works with Gmail, Outlook, Yahoo, iCloud and most other providers (see our Spark Mail review). If you came to Shortwave looking for a replacement for Google's old Inbox app, see our list of the best alternatives to Inbox by Gmail.

Shortwave Email Review Verdict

After several weeks of testing, I think Shortwave is one of the most complete AI email apps for Gmail. Its AI assistant is the reason to use it: it searches, writes, schedules, and even offers to tidy your inbox. It works best when you treat its output as a draft and give it a quick check before you confirm.

The Gmail-only restriction rules it out for many potential users, and the price has gone up: a paid plan now starts at $18 a month.

Fortunately, Shortwave has a free plan, so there's nothing stopping you from testing it out yourself.

Who should use Shortwave?

• Gmail users who want an AI-first email experience
• Teams looking for collaborative email features
• People whose emails are mostly tasks and who want to manage them like a to-do list
• Those who are comfortable with cloud-based AI processing

Who should look elsewhere?

• Users of non-Gmail email services
• Those who mainly want to clean up years of old email
• Users in highly regulated industries with strict data processing requirements
• Individuals who want AI email help on a small budget
