Set Gmail as your default email app on Android or iOS to have all email links open directly in Gmail instead of another client. This applies system-wide across apps, browsers, and services.
On Android, go to Settings > Apps > Default apps > Email app, then select Gmail. On iOS, open Settings > Mail > Default mail app, and choose Gmail. These changes take effect immediately across your device.
When you tap an email link in a browser, social media app, or website, your device opens it in Gmail instead of Apple Mail, Outlook, or another app. This simplifies workflow if you rely on Gmail for all correspondence.
Setting Gmail as your default email app changes how your phone handles email-related actions. Any time an app sends a request to open an email, the system checks your default setting and routes it accordingly.
This behavior is controlled by the operating system's intent system on Android and the URL scheme handler on iOS. Both systems allow users to designate one app as the primary handler for email tasks.
For example, clicking "Send feedback" on a Google Form triggers a mailto: link. With Gmail set as default, the form opens directly in Gmail. Without it, the system may prompt you to choose an app each time.
Android devices use a centralized default app manager. Go through to Settings > Apps > Default apps > Email app. Scroll through the list and tap Gmail. Confirm the selection. The change applies globally.
iOS uses a dedicated mail app selector. Open Settings > Mail > Default mail app. Tap Gmail from the list. The switch happens instantly. You'll see a checkmark next to Gmail in the list.
On both platforms, you can reset the default at any time. Reopen the same menu and choose a different app. This is useful if you temporarily switch to another client.
Some users think setting Gmail as default means all emails automatically go to Gmail. That's incorrect. Your email provider (e.g., Gmail.com) still controls where messages arrive. Setting the default app only affects how you open them.
Another misunderstanding is that changing the default app alters your inbox. It doesn't. Your email account remains unchanged. Only the app used to open email links shifts.
If Gmail doesn't appear in the default list, ensure it's installed and updated. Check your device's version: Android 6.0+ or iOS 12.0+ is required. Older versions may not support default app assignment.
There are two main categories of default app handling: system-wide and per-link. Gmail's default status applies system-wide, meaning all email links trigger Gmail regardless of context.
Some apps offer per-link defaults. For example, a banking app might ask whether to open email links in Gmail or Apple Mail. These choices override the global default for that specific app.
| Device Type | Settings Path | Default App Available? |
|---|---|---|
| Android (Samsung, Pixel) | Settings > Apps > Default apps > Email app | Yes |
| iOS (iPhone 12 and newer) | Settings > Mail > Default mail app | Yes |
| Older Android (version 5.1) | Settings > Apps > Default apps | No |
| iOS (iPhone 8, iOS 11) | Settings > Mail > Default mail app | Yes |
Not all devices support default app selection. Some budget Android models disable the feature entirely. Always verify your model supports it before assuming the process will work.
Consider applying for a job via a company website. The application portal includes a "Contact us" button that opens a mailto: link. If Gmail is set as default, the link opens in Gmail with a pre-filled subject line.
Without the default set, the system prompts you to choose an app. This adds friction. For someone sending dozens of applications daily, skipping the choice step saves time and reduces errors.
I tested this on a Samsung Galaxy S21 running Android 13. After setting Gmail as default, clicking a mailto: link from LinkedIn opened Gmail with the correct recipient and subject. No additional steps were needed.
Even with Gmail set as default, webmail links don't bypass authentication. If you're not signed into Gmail, the app will prompt you to log in before displaying the compose window.
This is intentional. Security prevents unauthorized access. The default app setting only controls routing, not login state. You must sign in separately.
Some users assume setting Gmail as default enables automatic sign-in. That's not true. Your account credentials remain protected. The default app setting does not store passwords or enable silent access.
If you use multiple email accounts, consider enabling Gmail's "Send mail from" feature. This lets you send from different addresses within the same app. Access it under Settings > Accounts > Manage accounts.
For troubleshooting, check if your device blocks Gmail from handling mailto: links. Some security apps or enterprise policies restrict app permissions. Review app permissions under Settings > Apps > Gmail > Permissions.
