Gmail Release Notes

Gmail storage and delivery enhancements for Enterprise Plus

We are introducing a significant enhancement to Gmail’s storage and delivery capabilities for Enterprise Plus customers. To support seamless collaboration and high-fidelity file sharing, we are increasing the file size limits for both sending and receiving emails.

• Sending larger files: Users can now attach files up to 50MB directly to an email (doubling the previous 25MB limit). This allows users to send large presentations, comprehensive spreadsheets, and high-resolution PDFs as direct attachments without needing to upload them to Google Drive first.
• Receiving larger files: We are increasing the total incoming message size limit to 70MB to also support large messages and attachments. This ensures that your organization can successfully receive larger emails from external senders, improving interoperability with other email platforms.

We know that today's workflows often involve sharing data-rich files. This new update compliments our existing functionality that allows users to upload to Google Drive and share a link. While Drive is excellent for collaboration, sometimes a direct attachment is the preferred method for external partners, clients, or regulatory workflows.

This update directly addresses two key areas of friction by:

• Streamlining workflow: Users can now simply drag and drop files up to 50MB into their draft window. This reduces context switching and saves time when sharing final versions of documents.
• Improving interoperability: Users who collaborate with partners who are unable to use Drive can now leverage attachments for these larger files, ensuring these critical communications are available regardless of the recipient.

This feature is admin configurable, giving admins more control over your organization's bandwidth and storage policies.

Getting started

• Admins: Visit the Help Center to learn how to configure your settings to unlock 50M attachments for your users.
• End users: There is no end user setting for this feature.

What’s changing

In 2025, we introduced the ability to react to emails in Gmail with emojis. This feature lets users respond quickly to acknowledge receipt of an email in a fun, informal and more authentic way. While initially enabled as an opt-in feature for early customer access, starting February 9, 2026, emoji reactions in Gmail will be enabled by default.

Organizations wishing to disable this feature can do so at any time in the Admin console, and the feature will not be enabled by default for organizations who have previously disabled or modified this feature setting in the Admin console (check the Audit & Investigation tool to confirm).

Whether you’re using a ‘thanks’ emoji to express gratitude, voting for a team dinner with a food emoji, or congratulating your client for reaching a milestone with a celebratory emoji, emoji reactions provide an expressive and more personal way to respond to emails.

Note that reactions cannot be sent in certain scenarios, for example if an email was received via a Google Group email alias or if there is a Google Group on the recipient list. Visit the Help Center to learn more about these scenarios.

Getting started

• Admins: If you do not wish to have emoji reactions on by default, visit the Admin console (Apps > Gmail > End User Access > Emoji reactions) before February 9, 2026, and ensure the setting is unchecked before clicking “Save.” Even if the setting is already unchecked, we suggest clicking “Save” to ensure it does not default to enabled on February 9. Visit the Help Center to learn more about managing Gmail settings for your users.
• End users: Emoji reactions are best experienced via the Gmail app on Android and iOS and via Gmail.com on the web. Visit the Help Center to learn more about replying to emails with emoji reactions and why you may get emoji reactions as an email.

Rollout pace

• Rapid Release and Scheduled Release domains: Admin console setting available now. Unless changed per the instructions above, it will be default enabled on February 9, 2026.

Availability

• Available to all Google Workspace customers.

Earlier this year, data classification labels for Gmail became generally available. Admins can use this feature to classify and audit email content according to organizational guidelines (“Sensitive,” “Confidential,” etc.) and apply policies, such as data loss prevention (DLP) rules, to protect sensitive information in email messages.

We have expanded this functionality to include the ability to create a DLP rule that adds a header or footer message to email messages. Critically, header and footer messages will be shown to users outside of your domain, which helps ensure external users are aware of the sensitivity of the message and any handling requirements. DLP rules are applied to outbound messages from your domain based on how you have configured the rule scope and conditions. As a reminder, the actual classification label is only visible to recipients in your domain.

Admins can customize the information shown in the header or footer message, including links to further information on handling information. Headers and footers are visible on all device types, both within and outside of your domain.

Selecting “Add footer message” when creating a rule

Once the email is sent, the banner will appear in the body of the email.

For more information on data classification labels for Gmail, please refer to our previous announcement.

Getting started

• Admins: Visit the Help Center to learn more about getting started with classification labels, Gmail DLP & automatic classification labels, and preventing data leaks in email and attachments.
• End users: No action is required. Footers will automatically be applied to your messages depending on your admin configuration.

Rollout pace

• Rapid Release and Scheduled Release domains: Available now

Availability

Data loss prevention rules with labels as a condition or labels as an action are available to:

• Enterprise Standard and Plus
• Education Fundamentals, Standard, Plus, and the Teaching & Learning Upgrade
• Frontline Standard and Plus

Overview

We’re launching a new integration between Gmail and Google Chat designed to improve team collaboration and productivity. With this feature, you can easily share a conversation from your Gmail inbox to a Chat direct message or space. No need to start your chat conversation with, "Did you see the email I forwarded?" or dig through your inbox to find the message being discussed.

Starting from a Gmail thread, you can initiate a chat with the existing email recipients, a subset, or a new group. The email is automatically forwarded and recipients can open it directly from a link in Chat.

This enables you to switch to Chat for active discussion while preserving the connection to the original message. Two-way linking helps ensure that everyone has the full context they need for a productive discussion and reduces the need to jump between tabs.

This feature is helpful in common scenarios such as:

• Resolving an issue in real time instead of going back and forth over email
• Chatting about an email with a subset of the original group before responding
• Discussing a customer email with coworkers
• Signal boosting an announcement by company leadership
• Sharing meetings notes and action items

Getting started

• Admins: There is no admin control for this feature. Organizations must have both Gmail and Chat enabled for the feature to appear.
• End users: This feature will be on by default for users who have Chat enabled in Gmail, available on desktop at launch and on mobile soon (currently available in limited testing on mobile for selected users). Visit the Help Center to learn more about how to share in Chat from Gmail.

Rollout pace

• Rapid Release domains: Full rollout (1–3 days for feature visibility) starting on December 2, 2025
• Scheduled Release domains: Extended rollout (potentially longer than 15 days for feature visibility) starting on December 9, 2025

Availability

Available for Google Workspace:

• Business Starter, Standard, and Plus
• Enterprise Starter, Standard, and Plus
• Frontline Starter, Standard, Plus
• Nonprofits

We plan to bring this feature to Education customers in the coming months. Please stay tuned to the Workspace Updates blog for an update on availability.

Gmail is enhancing user security by enabling the Cross-Origin Opener Policy (COOP). As a result, developers of websites and browser extensions opening or manipulating the Gmail page may have to update their code to ensure continued functionality when enforcement begins on January 20, 2026. There is no action needed from Workspace admins or end users.

COOP background

Cross-Site Search (XS-Search) is a type of Cross-Site Leaks (XS-Leaks) attack that targets query-based search systems, like Gmail. Attackers exploit this vulnerability by gaining control of a Gmail window, either by opening a new popup or accessing an existing one via its window handle. Once they have this access, they can gather information via a side channel to determine if specific search results exist by repeatedly loading different search terms, thereby leaking sensitive user data.

COOP is a web security feature designed to isolate the web applications from untrusted origins. This measure will prevent attackers from accessing Gmail's window handle, thereby protecting users from various Cross-Site Search (XS-Search) attacks that rely on window handles for collecting side-channel information, such as frame counting. This also significantly hinders attacks like cache probing, which rely on timing and other observations for resources that Gmail loads for search results. While these attacks don't directly collect side-channel information through the window handles themselves, COOP prevents repeated searches and thereby increases difficulty and reduces effectiveness, making them far less of a threat.

Who’s impacted

Websites or browser extensions that open Gmail in a pop-up window and interact with that window by accessing its properties (closed, location, length, focus) or invoking its functions (close, postMessage). Also, browser extensions that are injected into Gmail page and access the opener handle which is a reference to the window that opened the current Gmail page.

Additional details

To enforce COOP, the Cross-Origin-Opener-Policy header will be present in the response:

Cross-Origin-Opener-Policy: same-origin-allow-popups; report-to="gmail-web-coop-coep"
Report-To:{"group":"gmail-web-coop-coep","endpoints":[{"url":"https://csp.withgoogle.com/csp/report-to/gmail-web"}]}

Getting started

• Developers:
◦ For websites and browser extensions opening Gmail, refactor the offending code to avoid accessing the window properties or functions through the window handle and instead, utilize alternative APIs to achieve the desired functionality (e.g., chrome.tabs, Messaging).
◦ For browser extensions injected into the Gmail page, instead of trying to communicate with or access the opener, the browser extension should be updated so it doesn't need to interact with it at all and the extension's logic should be revised to work independently. If that is not possible, browser extensions can use existing APIs (e.g., chrome.tabs) to implement their logic.
• Admins:
There is no admin control for this feature.
• End users: There is no end user setting for this feature.

Rollout pace

• Enforcement will begin on January 20, 2026. Rollout will be extended (potentially longer than 15 days for feature visibility).

What’s changing

Finding time to meet — especially with external clients and customers — is hard, often requiring many back-and-forth emails. The new Gemini-powered Help me schedule feature in Gmail makes it easier for you to coordinate time with others.

Gmail with Gemini will detect when you’re trying to coordinate a time within an email and will surface a Help me schedule button in the toolbar. After you click on the Help me schedule button, Gemini will automatically suggest ideal slots based on your Google Calendar and the email's context. For example, if someone asks for a 30 minute meeting next week, Gemini will recommend time slots that fit your availability.

You can customize the times that Gemini suggests by removing or adding additional options, and then insert them directly into your Gmail message. Once the recipient receives the email and selects a time that works for them, a Calendar invite will automatically be added to both individual’s calendars. At launch, this feature will only support scheduling between two individuals, not groups.
