Gmail - Email by Google on iPhone: Setup, Features and Tips

“Gmail - Email by Google” is Google’s official Gmail app for iPhone and iPad, published by Google and listed as free with optional in-app purchases on the App Store. It handles Gmail plus other addresses like Outlook, Yahoo and iCloud Mail, can be set as your iPhone’s default mail app, and includes Gemini AI tools whose availability depends on your plan and region.

The app currently sits around #26 in the App Store’s app charts, which is why many people are looking it up right now. Below is what it actually does, how to set it up properly, and the details that tend to trip people up. Everything here reflects the listing and Google’s help pages as of October 2026; Google updates the app often, so menus and features may shift.

What the app is (and isn’t)

The App Store listing has the ID 422689480 and the developer is Google. Watch for that when installing, since search results can include lookalike third-party mail clients.

According to the listing description (as mirrored by app trackers), the app offers:

• Multiple account support, including non-Google addresses.
• Real-time notifications for new mail.
• Search across all your mail.
• Gemini in Gmail features such as summaries of long emails, drafting or refining replies, and searching your inbox.
• Google Workspace integration: join Google Meet or Google Chat, send a Google Calendar invite, or add an item to your task list without leaving Gmail.

What it isn’t: a paid app. The price is free. The in-app purchases listed by trackers such as App Pricing Lab are Google storage plans (for example 100 GB, 200 GB and 2 TB tiers). Prices differ by country and change over time, so treat any figure you see elsewhere as a snapshot and check the purchase sheet on your own device.

Device requirements

A regional App Store listing states the app requires iOS 17.0 or later on iPhone and iPadOS 17.0 or later on iPad. I could only confirm that minimum on one regional listing, so check the “Compatibility” section of the listing on your device. If your phone can’t run iOS 17, the App Store will tell you before you download.

Setting up the Gmail app on iPhone or iPad

1. Install Gmail - Email by Google from the App Store (developer: Google).
2. Open the app and sign in with your Google account. If you have 2-Step Verification on, Google may ask you to approve the sign-in on a trusted device.
3. Allow notifications when prompted if you want alerts for new mail. You can change this later in iOS Settings.

That’s it for a single Gmail or Google Workspace account. Work accounts may be subject to your organization’s policies, so if sign-in is blocked, talk to your admin.

Adding more accounts, including Outlook, Yahoo and iCloud

Google’s help page on adding or removing accounts covers this:

1. In the Gmail app, tap your profile picture in the top right.
2. Tap Add another account.
3. Pick the account type: Google, or a provider like Outlook, Yahoo or iCloud, or “Other” for anything else.
4. Follow the sign-in steps. For non-Google providers, Gmail offers automatic setup, or manual setup using your provider’s mail server settings.

A few things worth knowing:

• App passwords. Some providers won’t accept your normal password from a third-party app. Google notes that you may need an app password, and iCloud addresses (@icloud.com, @me.com, @mac.com) are a common case. You create that password in your provider’s account settings, not in Gmail.
• Switching accounts. Tap your profile picture to jump between accounts. The account list is where you add and remove addresses too.

Making Gmail your default mail app

Since iOS 14, Apple has allowed third-party email apps to be the default. 9to5Google reported in September 2020 that Gmail added support for this, so tapping an email address in Safari or another app opens a Gmail compose window instead of Apple Mail.

The exact menu path depends on your iOS version:

If neither path matches your phone, search “Default” in the iOS Settings search bar.

Gemini AI features: what to expect

This is the area with the most confusion, because what you see depends on your account type.

What the listing promises. The App Store description says Gemini in Gmail can summarize lengthy emails, help write or refine replies, and search your inbox. It also mentions Help me write, suggested replies, AI Overviews and proofreading. The listing itself notes that some Gemini features may need a paid Google AI subscription and that language and country availability varies.

How it got here. Gemini’s question-and-answer feature arrived on the iOS app in October 2024, after Android. Business Standard reported at the time that it let you ask about specific emails, find unread messages or mail from a particular sender, and summarize emails on a topic, but only for Google One AI Premium subscribers or Workspace accounts with Gemini add-ons. Plan names have changed since then.

What’s changed recently. Google’s Gemini features in Gmail help page says Google AI Pro and Google AI Ultra subscribers in the US may no longer see Ask Gemini in Gmail or be able to open the Gemini side panel. AI Overviews and Help me write continue to be available directly in the product. If a feature you read about elsewhere is missing, this is the likeliest reason, not a bug on your phone.

In short:

I couldn’t find an official Google changelog listing every 2026 change to the iOS app, so treat third-party claims about brand-new features with caution until Google confirms them.

Practical tips for daily use

• Turn off notifications for accounts you only check occasionally. With several accounts in one app, alerts pile up fast. Check the notification options in the app’s settings, and use iOS Settings to control whether Gmail can notify at all.
• Keep one app for mail if you can. Having both Apple Mail and Gmail pulling the same account works, but it doubles notifications and makes it unclear where you read what. Setting Gmail as default (above) and silencing the other app avoids that.
• Update the app. Features like default-app support and Gemini tools arrived through app updates. If something in this guide is missing, update from the App Store first.
• Sign in only through the official app or Google’s own sign-in screen. Never enter your Google password into a third-party site that claims to “unlock” Gmail features.

Should your team standardize on it?

For teams already on Google Workspace, the Gmail app is the obvious mobile client: Meet, Chat, Calendar and Tasks are one tap away, and admins control Workspace features centrally. For people juggling a Gmail address alongside Outlook or iCloud, it works well as a single inbox, with the caveat that non-Google providers sometimes need app passwords. If AI features are part of your reason for choosing it, check exactly what your plan includes in your country before assuming the full feature list from the App Store applies to you.
