Install the email extension
The personal inbox connection lets you send emails from HubSpot. The email extension (or add-in) does the reverse: it lets you use HubSpot sales tools from within Gmail or Outlook directly.
With the extension installed, you get checkboxes for logging and tracking on every email you compose in your native inbox. You can also insert templates, meeting links, and documents without switching to HubSpot.
To install it: go to Settings > General > Email, and you'll see the option to download the extension for your email provider. There are versions for Gmail (Chrome extension), Outlook (desktop add-in), and Office 365 (web add-in).
Understand logging vs tracking
These two features appear side by side in the extension, and reps often confuse them.
Logging saves a copy of the email to the contact's timeline in HubSpot. It also lets you associate the email with specific records: a contact, a company, a deal. This is about record-keeping.
Tracking adds an invisible pixel to the email that tells you when the recipient opens it. This is about engagement signals. You'll see a notification when someone opens your email, which is useful for timing follow-ups.
Both are controlled by checkboxes in the extension. By default, they're usually both on, but reps can toggle them per email. The combination of logging + tracking gives you a complete picture: what was sent, when it was opened, and how the prospect engaged.
What to check after setup
Send a test email to a colleague (who is also a contact in your CRM) with both logging and tracking enabled. Then verify three things: the email appears on the contact's timeline in HubSpot, you see the email in your sent folder, and you receive an open notification when they read it.
If any of these fail, the most common causes are: the extension isn't installed correctly, the recipient's domain is on the never-log list, or your browser is blocking the tracking pixel.
