How To Enable Read Receipts | Across iPhone, Gmail, Outlook & Zoom

Read receipts work differently in every app: iPhone Messages offers a true enable switch, while Gmail and Outlook only let you request a receipt the recipient can decline, and Zoom Team Chat requires an admin to flip the setting.

The phrase “enable read receipts” sounds like one toggle that works everywhere. It doesn’t. On an iPhone, you can turn them on for iMessage conversations, but the setting lives in a different spot than most people expect. In email, neither Gmail nor Outlook gives you a guaranteed way to force someone to send one—you can only ask. And in Zoom Team Chat, you can’t even find the option unless you’re the account administrator. Here is exactly how to handle each one.

What Read Receipts Actually Do

A read receipt is a notification that tells the sender when you’ve opened their message. The behavior depends entirely on the platform. In iMessage, the receipt sends automatically once you open the message—unless you’ve disabled the feature. In Gmail and Outlook, sending a read receipt requires your action; it never happens by default. In Zoom Team Chat, the setting is company-wide, controlled by an admin.

Enable Read Receipts on iPhone (iMessage)

Apple gives you two ways to control read receipts in the Messages app: a global on/off switch, and per-conversation settings that override the global one.

Turn It On for All Conversations

1. Open Settings on your iPhone.
2. Scroll down to Apps (on older iOS versions, this is just Messages inside the main Settings list).
3. Tap Messages.
4. Toggle Send Read Receipts on.

Turn It On for One Person Only

This is the better option for most people—you don’t have to broadcast your reading habits to every contact.

1. Open Messages and tap the conversation with the person you want.
2. Tap the contact icon or the person’s name at the top of the screen.
3. Toggle Send Read Receipts on for that thread, even if the global setting is off.

The toggle turns green, and future messages from that contact will show “Read” under them after you open them.

Caveat: This only works for iMessage conversations (blue bubbles), not SMS texts (green bubbles). SMS has no read receipt system at all.

Request Read Receipts in Gmail

Gmail does not have a universal “enable” switch for read receipts, even if you’re on a paid Google Workspace plan. You can only request a receipt when composing a message, and the recipient gets to choose whether to send it.

How to Request One

• Open Gmail on a computer (this feature is not available on the mobile app).
• Click Compose and write your email.
• Click the three-dot More options menu at the bottom-right of the compose window.
• Select Request read receipt, then send the message.

When the recipient opens your email, Gmail will prompt them to send a receipt. They can tap Send receipts or Not now. You cannot force it.

Admin note: If you use a Google Workspace account through a school or company, your administrator must enable read receipts in the Google Admin console under Apps > Google Workspace > Gmail > User Settings > Email read receipts. Without that, the option won’t appear at all.

Request Read Receipts in Outlook

Outlook lets you request a receipt on individual messages or set a default for all outgoing mail. Like Gmail, the recipient can still decline.

Request for One Message

• While composing a message, go to the Options tab in the ribbon.
• In the Tracking section, check Request a Read Receipt.
• Send the email as usual.

Set It as a Default (Classic Outlook)

1. Go to File > Options > Mail.
2. Under Tracking, check Read receipt confirming the recipient viewed the message.
3. Click OK to save.

Caveat: The default-read-receipt setting is only available in the classic desktop version of Outlook, not the new Outlook or Outlook.com. Microsoft also notes that some tracking features require a Microsoft 365 Business plan with email included—free or personal accounts may lack them.

Enable Read Receipts in Zoom Team Chat

Zoom Team Chat read receipts are controlled at the account or group level, meaning only an admin can turn them on for everyone. You won’t find this setting inside the Zoom desktop app.

Admin Setup

1. Sign in to the Zoom web portal as an admin.
2. Go to Account Management > Account Settings.
3. Click the Team Chat tab.
4. Under Visibility, toggle Enable read receipts on.
5. Optionally, check Allow users to opt out so individuals can turn receipts off for themselves.

If you’re not an admin, you cannot enable read receipts on your own—ask your IT team.

Read Receipts Quick Reference

Common Mistakes to Avoid

• Mixing iMessage with SMS: Read receipts only work inside iMessage conversations (blue bubbles). Green SMS bubbles cannot send them.
• Assuming a request is a requirement: In Gmail and Outlook, requesting a receipt is not the same as enabling one. The recipient has full control over whether to send it.
• Forgetting about per-conversation overrides: iPhone Messages lets individual threads override the global setting. You can have receipts on for one person and off for everyone else.
• Expecting the option on every plan: Gmail read receipts require Google Workspace admin approval, and some Outlook tracking features require a Microsoft 365 Business plan.

Finish With the Right Approach for Each App

The takeaway is simple: on iPhone, turn the switch on in Settings or per conversation. In Gmail and Outlook, request a receipt and accept that the recipient can decline. In Zoom, talk to your admin. No single toggle works everywhere, but with these steps you’ll know exactly where to look in each app.
