Best Email Apps for Android in 2026
I’m going to be upfront: I built one of these apps (Airo Mail), so take my opinions with appropriate skepticism. But I’ve also used every email app on this list extensively. That’s how I knew what I wanted to build differently.
Here’s my honest take on each.
Gmail
Price: Free
On Android, Gmail is the default and it shows. Deep integration with the OS, reliable notifications, and full access to Google’s features (labels, filters, advanced search).
If you only use Gmail accounts, the official app is hard to beat. It’s fast, it’s familiar, and it just works.
The downsides: the interface is cluttered with Meet buttons and promotional tabs. And if you have non-Gmail accounts, the experience gets noticeably worse. Also, it’s Google, so your email data feeds their ad business.
Use it if: Gmail is your only account and you’re fine with Google’s data practices.
Skip it if: You have multiple accounts from different providers, or you want help processing email faster.
Samsung Email
Price: Free (on Samsung devices)
If you have a Samsung phone, you have this app. It’s decent. Clean interface, supports multiple accounts, integrates with Samsung’s ecosystem.
The problem: it’s basic. No smart features, no AI, no help managing high email volume. It displays your email and that’s about it.
Use it if: You have a Samsung phone, light email needs, and don’t want to install anything.
Skip it if: You’re drowning in email or want any kind of intelligence.
Microsoft Outlook
Price: Free
The enterprise standard. If your company runs on Microsoft 365, Outlook is probably the best choice just for compatibility.
Focused Inbox is genuinely useful. It learns which emails are important and surfaces those first. The calendar integration is tight. And unlike the iOS version, Outlook on Android feels reasonably snappy.
The downsides: the interface is busy. Microsoft keeps adding features (To-Do integration, etc.) that most people don’t need. And if you don’t use Microsoft 365, some of the best features don’t apply to you.
Use it if: Work uses Microsoft 365.
Skip it if: You want something lightweight, or you don’t use Microsoft services.
Spark
Price: Free for individuals, paid for teams
Spark has been around for years and built a loyal following with its smart inbox and team collaboration features. It automatically groups emails into categories (newsletters, notifications, etc.) and lets teams share drafts and discuss emails.
The problem: Spark recently bolted on AI features, and they feel like an afterthought. The AI doesn’t integrate well with the rest of the app. Many users report just turning off the AI entirely because it gets in the way more than it helps.
Use it if: You collaborate on email with teammates and don’t care about AI.
Skip it if: You want AI that actually works, or you want something lightweight.
Edison Mail
Price: Free
The “smart” free option. Edison does automatic categorization (travel, packages, subscriptions) and has one-tap unsubscribe.
The catch: Edison makes money by analyzing email data to generate market research. Your data is anonymized, but your shopping receipts and travel confirmations are being mined. That’s the privacy trade-off for a free app with smart features.
Use it if: You want smart features for free and don’t mind the data trade-off.
Skip it if: Privacy matters to you.
Airo Mail
Price: Free trial, then $9.99/month
This is mine, so obviously I’m biased. I’ll tell you why I built it and let you decide if those reasons resonate.
I built Airo because I was drowning in email and existing apps weren’t helping. They all focus on displaying messages; none of them help you process messages faster.
AutoFile is the core feature: AI that learns what you care about and automatically archives the rest. You train it with a few taps (“yes, archive emails like this” or “no, keep these”), and over time your inbox only shows what matters.
The interface is designed for your thumbs. I have carpal tunnel, and tiny buttons at the top of the screen were killing me. Important actions are where your thumbs naturally rest.
Use it if: You’re overwhelmed and want AI to handle the sorting.
Skip it if: You get minimal email and don’t need automation.
The Honest Truth
There’s no universally “best” email app. There’s only the best app for your situation:
- Gmail-only power user → Gmail
- Samsung phone, light needs → Samsung Email
- Microsoft 365 at work → Outlook
- Team collaboration → Spark (but skip the AI)
- Free with smart features → Edison (with privacy trade-offs)
- Overwhelmed and want automation → Airo
The worst thing you can do is stick with an app that isn’t working for you. If you’re drowning, try something different.
