AI is no longer something you have to install or sign up for separately. For many people, it is already built into their email inbox, helping draft messages, suggest replies, summarize long conversations, and filter spam. These tools are offered by major providers, often at no additional cost, and in many cases are enabled by default.

In this week’s Tech Tip Tuesday, we are breaking down where AI shows up in your inbox today, what the biggest providers offer, and most importantly, how to turn these features on or off so you stay in control.

Gmail by Google

What AI features Gmail uses

Gmail uses AI to power features such as Smart Compose, Smart Reply, inbox nudges, spam and phishing detection, and contextual suggestions. These tools help finish sentences as you type, offer quick reply buttons, and surface important emails.

How to turn Smart Compose and Smart Reply on or off (desktop)

1. Open Gmail in a web browser.
2. Click the Settings gear icon in the top right.
3. Select See all settings.
4. Stay on the General tab.
5. Scroll to Smart Compose.
6. – Select Writing suggestions on to enable
7. – Select Writing suggestions off to disable
8. Scroll to Smart Reply.
9. – Check or uncheck Enable Smart Reply
10. Scroll to the bottom and click Save Changes.

How to turn Smart Compose and Smart Reply on or off (mobile)

1. Open the Gmail app.
2. Tap the menu icon and go to Settings.
3. Select your email account.
4. Toggle Smart Compose and Smart Reply on or off.

Important note on Smart Features

Some Gmail features like package tracking summaries and event suggestions are controlled by Smart features and personalization.

To manage those:

1. Go to Gmail settings on desktop.
2. Under the General tab, find Smart features and personalization.
3. Toggle these on or off depending on how much automation you want.

Outlook by Microsoft

What AI features Outlook uses

Outlook includes AI assisted features such as Suggested Replies and other writing assistance tools. Some users may also have access to Copilot features if their account includes a paid Copilot license.

Outlook’s settings layout varies by version, region, and account type. You may see AI related options under either Smart suggestions or Compose and reply. Both are correct.

How to manage Suggested Replies in Outlook

1. Sign in to Outlook.com or Outlook on the web
2. Click the Settings gear icon
3. Select Mail
4. Select Smart suggestions or Compose and reply
5. Locate Suggested replies
6. Toggle Show suggested replies on or off
7. Click Save

About text predictions and other AI tools

Some Outlook users may see an option for Text predictions under Smart suggestions. If it appears, it can be toggled on or off. If it does not appear, the feature is not available for that account or region. This is expected behavior.

Other writing assistance may be provided through Microsoft Editor or Copilot and may not have a single global toggle.

Apple Mail A Deliberate Contrast

Apple Mail takes a noticeably different approach compared to Gmail and Outlook. It does not use cloud based generative AI to draft replies, summarize conversations, or analyze email content for writing assistance. Instead, Apple focuses on limited, on device intelligence aimed at organization rather than content creation.

In practice, this means Apple Mail may prioritize important messages, improve search accuracy, or suggest contacts using local device data. These features run on the device and are designed to avoid sending email content to external AI models.

For users and organizations that prefer fewer automated features and stronger privacy boundaries, this approach can be appealing. There are no AI writing tools to manage or disable and no inbox level AI responses being generated behind the scenes.

Apple’s design highlights an important point. AI in email is a choice, not a requirement. Some platforms emphasize productivity through automation, while others prioritize simplicity and privacy by design.

Free AI Tools That Work With Any Inbox

Tools like ChatGPT and Claude can be used to draft emails, summarize threads, or rewrite messages by copying and pasting text. Free versions work well for everyday use.

Avoid pasting sensitive business data, passwords, or client information into these tools unless you understand how that data is handled.

Browser extensions and AI keyboards can also assist with email writing, but always review permissions carefully since many require access to email content.

Using Inbox AI Safely

AI can save time, but it does not replace judgment. Always review suggested replies before sending. Be cautious with sensitive information, and remember that attackers also use AI to craft more convincing phishing emails.

Enable multifactor authentication on email accounts and treat unexpected or urgent requests with extra scrutiny.

Bottom Line

AI is already part of most inboxes whether you realize it or not. Gmail, Outlook, and Apple Mail all include intelligent features that can be helpful when used intentionally. Knowing where these tools live and how to control them ensures you get the benefit without losing visibility into how your data is handled.
