What This Update Actually Is
HubSpot shipped AI-powered editing controls directly inside the Gmail Compose toolbar. This is part of the HubSpot Sales Chrome Extension, and it requires version 3.1.1.43314 or later.
While composing an email in Gmail, reps click the AI button in the compose toolbar. That opens the "Edit with Breeze" modal. From there, four actions are available:
- Rewrite: regenerates the selected text with stronger clarity or messaging
- Shorten: trims the message without losing the core point
- Expand: adds detail and context to a rough draft
- Change Tone: adjusts formality, warmth, or urgency to match the moment
When Breeze generates the updated content, one click on Replace swaps the entire email body inline. The rep never leaves Gmail.
Why HubSpot Shipped This
Here's the friction HubSpot was trying to kill: reps write outreach emails in Gmail, but Breeze's AI editing tools lived inside the HubSpot CRM composer. Two different surfaces. Two different tabs.
We've seen this pattern across dozens of portals. A rep writes a solid first draft in Gmail, wants to tighten it up, and either sends it as-is or burns two minutes switching to HubSpot to use AI tools, then copying the result back. That's not a workflow. That's friction wearing a workflow costume.
The internal frustration is real too. Sales reps don't want to feel like they need a system administrator's tour of HubSpot just to clean up one cold email. This update removes that barrier entirely.
The deeper reason HubSpot shipped this is strategic. Breeze is being woven into every surface where humans do real work. Gmail is where most sales reps live. This puts HubSpot's AI layer exactly where it's needed, without asking the rep to change their habits.
How to Use It Step by Step
Before you do anything else, check your extension version. This won't work on an older build.
- Update the HubSpot Sales Chrome Extension to version 3.1.1.43314 or later. Go to chrome://extensions, find HubSpot Sales, and confirm the version or click Update.
- Open Gmail and start composing a new email or reply. The AI button will appear in your compose toolbar once the extension is updated.
- Click the AI button in the Gmail compose toolbar to open the "Edit with Breeze" modal. Your email draft loads alongside the Breeze editing controls.
- Choose an action: Rewrite, Shorten, Expand, or Change Tone. Highlight specific text first if you want to edit only a portion, or let Breeze work on the full body.
- Review Breeze's suggestion in the modal. If it looks right, click Replace. The updated content drops inline into your Gmail draft instantly.
- Send. Done. The email logs to the HubSpot CRM contact record automatically because you're using the connected Gmail extension.
One important caveat: this works within the connected Gmail experience. If your HubSpot Gmail integration isn't set up or your extension is outdated, none of the above will appear. Get the extension updated first.
What It Touches in Your HubSpot Strategy
This update sits squarely inside Sales Hub, but its ripple effect touches several adjacent areas.
Sales sequences and templates: if your team uses HubSpot sequences, reps often customize template steps before sending. Now they can use Breeze to personalize those edits inside Gmail before hitting send, which means better personalization without extra tools.
CRM data and contact context: because the Gmail extension is connected to HubSpot, Breeze has access to contact data, deal stage, and the relationship history logged in the CRM. That context shapes what Breeze suggests. It's not generic AI. It's AI with your CRM data behind it.
Brand voice and tone consistency: the Change Tone action is especially useful for teams that have defined brand voice standards. Pair this with Breeze Canvas surfacing relevant CRM info while you write for a two-layer approach to AI-assisted email quality.
Key Takeaway
Breeze's editing actions in Gmail are informed by your CRM data. This isn't a generic AI writing tool bolted onto your inbox. It knows who the contact is, what deal stage they're in, and what's been said before.
Email logging and reporting: every email sent through the connected Gmail extension logs to HubSpot automatically. Your open rates, reply tracking, and sequence analytics aren't affected by using Breeze editing. The data pipeline stays intact.
If you're still getting your bearings on what Breeze can do across HubSpot, this breakdown of Breeze Assistant's full capabilities is worth reading alongside this update. The Gmail editing feature is one piece of a much larger Breeze rollout.
Key Takeaway
Update the Chrome extension before your next team standup. Version 3.1.1.43314 is the gate. Without it, reps won't see the AI button in Gmail at all, and no amount of troubleshooting will fix what's really just a version gap.
Who Should Care Most
This update is most immediately useful for the following roles and profiles:
- Sales reps and BDRs who live in Gmail and send high volumes of personalized outreach. This cuts the time between first draft and send-ready email.
- Sales managers who care about message quality and consistency. Change Tone gives reps a fast way to match the appropriate register for enterprise prospects versus SMB leads.
- RevOps and Sales Enablement leaders who manage HubSpot portal hygiene. You'll want to verify that all reps are on the required Chrome extension version before promoting this feature.
- Small business owners and founders who write their own outreach. You don't need a copywriter to send a sharper email now. Breeze handles the polish.
One profile that can wait: HubSpot admins and marketing ops humans who do most of their email work inside HubSpot's native email tools. This update is specifically for Gmail Compose. If your team doesn't use Gmail or doesn't use the Chrome extension, this one isn't for you right now.
George's Take
“The best AI tool is the one that shows up where the human already is. HubSpot just did that for every sales rep who lives in Gmail. Don't overthink it. Update the extension, try it on your next draft, and watch what happens to your reply rates.”
I've been watching HubSpot push Breeze into more and more surfaces this year, and this Gmail update is one of the most practical moves yet. We talk a lot about agentic AI and what the future looks like. But the wins that actually move revenue are the small ones: fewer tabs, less copy-pasting, more time talking to prospects. This is that kind of win. If you want the bigger picture of where HubSpot's AI layer is heading, the HubSpot agentic platform guide lays it all out. But for today, just update your extension and let your reps feel what it's like to have a writing assistant that doesn't ask them to leave their inbox.

Frequently Asked Questions
What version of the HubSpot Sales Chrome Extension do I need for AI email editing in Gmail?
You need version 3.1.1.43314 or later of the HubSpot Sales Chrome Extension. If your extension is on an older version, the AI button won't appear in the Gmail Compose toolbar. Go to chrome://extensions, find HubSpot Sales, and update it before expecting this feature to work.
What AI editing actions are available in Gmail Compose with HubSpot Breeze?
Four actions are available: Rewrite, Shorten, Expand, and Change Tone. You can apply them to a highlighted selection or to the full email body. Once Breeze generates a suggestion, click Replace to swap the email content inline without leaving Gmail.
Does HubSpot's AI email editing in Gmail use my CRM data?
Yes. Because the feature runs through the connected HubSpot Gmail extension, Breeze has access to contact data, deal stage, and relationship history stored in your HubSpot CRM. This means the AI suggestions are informed by your actual sales context, not generic writing patterns.
Will emails edited with Breeze in Gmail still log to HubSpot?
Yes. Emails sent through the connected Gmail extension log to HubSpot automatically, just as they did before. Using Breeze editing doesn't change the logging behavior, so your open rate tracking, reply detection, and sequence analytics remain intact.
Which HubSpot plans include AI email editing in Gmail?
This feature is available to all HubSpot hubs and tiers, including free accounts. The only requirement is that you have the HubSpot Sales Chrome Extension installed and updated to version 3.1.1.43314 or later, and that your Gmail account is connected to HubSpot.
How is this different from using Breeze AI inside HubSpot's native email composer?
HubSpot's native email composer already had Breeze writing tools, but reps who write outreach in Gmail had to switch tabs to access them. This update brings those same controls directly into the Gmail Compose toolbar, eliminating the context switch entirely and keeping reps in their primary workflow.
