I replaced Gmail with an email app that finally makes inbox zero feel realistic

If numbers aren't your thing, you can probably steer clear of a career that has you crunching them all day. If programming makes your head hurt, there are plenty of professions where you'll never have to write a single line of code. There are countless tasks like these that you can avoid simply by choosing a field that doesn't require them. Email, unfortunately, isn't one of them. Whether you're a college student checking for an update from a professor, a journalist digging through pitches, or someone working a regular 9-to-5, your inbox is probably one of the first places you end up every day. No matter what you do for a living, what you do within that inbox is universal: read, reply, archive, snooze, sort, and somehow try to make sure nothing important gets buried underneath everything else. When it comes to email clients, I've stuck with Gmail, as have plenty of people already deep within Google's ecosystem. A few days ago, though, I came across a tool called Shortwave that's designed around the idea that your inbox should be more than just a never-ending list of messages. Its entire approach revolves around keeping that inbox organized, actionable, and, ideally, empty. Naturally, I had to see whether it could actually make inbox zero feel as realistic as it sounds. Shortwave has an entire philosophy for dealing with email No more remembering emails at 3 AM I am terrible at responding to emails. My colleagues, media contacts, and professors would wholeheartedly agree with that, and I'm terribly sorry for unintentionally leaving so many of them hanging. Now, it's rarely because I don't want to reply to someone (sometimes, it might be... just kidding). More often than not, I'll open an email, realize it warrants a proper response rather than a rushed one, tell myself I'll get back to it later, and then watch it slowly disappear beneath everything else that lands in my inbox. Ironically, the memory of these emails will hit me at no time other than 3 AM, when replying would probably be stranger than simply leaving them unanswered until morning. By then, of course, there's a good chance I'll forget all over again. Of course, my approach isn't the best. In fact, Shortwave's entire philosophy is designed to stop you from doing exactly what I do. The Shortwave Method follows the Only Handle It Once (OHIO) principle. The idea is that instead of opening an email, reading it, and leaving it sitting there for future you to deal with, you make a decision about it the first time you come across it. In its support documentation, Shortwave compares the whole system to a world-class chef working in a kitchen, where your inbox is the kitchen. A chef wouldn't start cooking while their workspace is cluttered with dirty dishes and ingredients scattered everywhere. They'd clean and organize everything first so they can actually focus on the work in front of them. Shortwave wants you to treat your inbox the same way: clear the clutter, decide what each email needs from you, and only then move on to the deeper work. Shortwave splits everything in your inbox into three broad categories. If an email doesn't require any action, you mark it Done, delete it, or snooze it until it actually becomes relevant. If whatever it needs from you will take less than two minutes, you deal with it immediately and then mark it Done. Anything that requires more time gets turned into something actionable using a Star or Todo (more on this below), which you can come back to once you've finished triaging the rest of your inbox. Shortwave has features built around actually acting on email No more leaving emails for Future Me Beyond just establishing a philosophy for how you should approach your inbox, Shortwave has features built specifically around helping you follow it. The option to quickly turn any email into a to-do is my personal favorite. All you need to do is select any email and press T to turn it into a to-do. Rather than just adding the subject-line of the email as a to-do (which is what Gmail does), Shortwave uses AI to create a one-line task summary linked to the thread. This is perfect for the emails that need more than a couple of minutes of my attention, and it ensures I actually come back to them rather than just letting them slip away. Todos become even more useful when one task spans multiple conversations. Shortwave lets you select several email threads and group them under a single Todo. So, if I'm dealing with an event and have separate emails for travel, meetings, press materials, and logistics, I don't need four or five separate reminders cluttering my inbox. Instead, they can all live under one task instead. Then there are Splits, which let you divide your inbox into separate tabs for different types of email. Shortwave actually introduces you to the idea during onboarding, where you can choose between a single inbox, an Important + Other layout, or Gmail-style tabs. I went with Important + Other initially, which automatically separates higher-priority emails from everything else. You aren't stuck with those defaults, though. Custom Splits can be built around labels, individual contacts, or much more specific search queries. You can filter by sender, recipient, subject line, attachment name or type, date, whether an email is unread, and more, then combine several of those conditions using OR. You can also choose to hide a Split entirely when it's empty and decide how emails within it should be bundled. I've been using this to separate different types of email rather than having everything compete for space in one giant inbox. For instance, I get a lot of emails from PR contacts. While the majority of these emails are genuinely important, I also get messages from my bank, colleagues, newsletters, and all sorts of automated services throughout the day. Having a dedicated PR Split gives those emails their own place instead of forcing me to dig through everything else whenever I'm specifically dealing with pitches or media outreach. Todos also get their own dedicated Split by default, which is something I've found particularly handy! It makes the whole system feel a lot more intentional than simply starring an email and hoping I remember it later. Shortwave lets me decide when email deserves my attention Not every email deserves me right now One of the biggest problems I have with email is that everything arrives with roughly the same level of urgency. A message from someone I need to reply to can land right next to a newsletter, a promotional email, or an automated update from a service I barely remember signing up for. Shortwave gives me a lot more control over when those different kinds of emails are allowed to demand my attention. Bundles are one way it does this. Instead of letting related emails take up separate rows in my inbox, Shortwave can group them together into a single item. Built-in labels like Newsletters, Promotions, and Travel can be bundled automatically, but you can also create bundles using your own labels or specific senders. From there, you can snooze, delete, or mark the entire bundle Done in one go rather than dealing with every message individually. Delivery Schedules take that idea even further. Rather than simply snoozing an email after it has already interrupted me, I can decide when certain types of emails should enter my inbox in the first place. Shortwave lets you apply a schedule to a label or contact, which means something like newsletters can be held back until Saturday morning instead of trickling in throughout the week. That distinction is probably one of my favorite things about Shortwave so far. There are emails I want to receive, but that doesn't mean I want to see them the second they arrive. Newsletters are the obvious example. I enjoy reading plenty of them, but having one appear in the middle of a workday is usually just another distraction. Putting them on a delivery schedule means they can all arrive when I'm actually in the mood to read them instead! The AI stuff is probably my least favorite part Using AI to draft emails might still be most users' primary use case for AI, but I've never been big on that. Perhaps that's because writing is quite literally what I do for a living. This is why I'm not a fan of the flashy AI features Shortwave puts front and center, like drafting replies for me and suggesting what I should say next. While using AI to organize my inbox and filter out my emails is something I find handy, the privacy concern does sneak in here too. Shortwave processes your emails to power features like search, threading, labeling, and its AI Assistant, and says some customer data may be sent to subprocessors including OpenAI, Anthropic, and Pinecone when necessary to provide the service. The company does say your data isn't used to train third-party AI models, and that most of its AI workloads run on open-source models on hardware it controls. That still means I'm giving yet another service access to an inbox that contains everything from work conversations to financial emails and personal correspondence. For me, that's enough to make features like AI-generated replies feel less appealing, especially when I don't really need them in the first place!
