How does hubspot track email opens

When you send a tracked email from your email inbox using the HubSpot Sales Chrome extension, HubSpot Sales Office 365 add-in, or HubSpot Sales Outlook desktop add-in, or if you send a one-to-one email from a record, HubSpot will track email opens. If you're a user with an assigned Sales Hub paid seat, HubSpot will also track when the recipient clicks a link in the email.

Please note: because of changes related to Apple's recently announced iOS 15 privacy features, your sales email opens may appear higher than usual. Learn more about how to navigate these changes in HubSpot.

Email opens

Please note: if you've enabled General Data Protection Regulation (GDPR) functionality in your account, email opens can only be tracked for contacts with an assigned legal basis for data processing. Learn more about how GDPR impacts email tracking with the Chrome or Office 365 extension.

When you send a tracked email, HubSpot embeds an invisible one-pixel image into the email message once it is sent. When your recipient views the email and the images load, you will receive a notification that the email has been opened.

If the recipient's email client doesn't allow the track pixel to load, HubSpot will not be able to track the email open. HubSpot tracking can be deactivated in the following situations:

  • The recipient formats their email in plain text.
  • The recipient's email client doesn't automatically download images.
  • The recipient's corporate filter strips away all images for incoming emails.

If the recipient has a very strict spam filter where they block any images or link tracking from loading in emails, your tracked email could be filtered as spam. However, email tracking tools are common, and the majority of email clients will not view your email any differently than before.

If you don't want to track one-to-one emails, learn how to disable email tracking for all users in your account.

Why am I getting multiple email opens for a specific tracked email?

If you receive moreemail open notificationsthan expected for a specific tracked email, it may indicate that the email was forwarded or that you copied and pasted a previously sent email. Because of privacy and security concerns, when an email is forwarded, HubSpot defaults to telling you that the original sender opened the email again.

If you copied and pasted an email that you previously had sent, you also copy the original tracking pixel. The same tracking pixel would load for each recipient. It is recommended to send personalized emails, which you can create fromscratch in the CRMor your mail client, or to usesales email templates.

Sometimes, a single tracking image will load multiple times because of how the recipient views their emails. For example, a user could be on a server that dynamically changes that user's IP address. If the image is loaded from multiple IP addresses, then the notifications may indicate that your emails were opened by multiple people.

Also, email clients like Outlook or Apple Mail have a preview pane as part of the inbox view. If recipients scroll over your email in their inbox, this can trigger an email open notification.

What if I'm getting a 'Someone' notification?

You may see a 'Someone' notification if one of the following occurs:

  1. If you send a tracked email to multiple email addresses (including CC and BCC), they all receive the sameHubSpot Sales tracking image.HubSpotwill still notify you of the email open, but HubSpot may not be able to determine which recipient opened the email.
  2. If you have the General Data Protection Regulation (GDPR) toggle enabled in your HubSpot accountand a contact does not have alawful basis for data processing, HubSpot Sales will track emails you send to that contact, but the notifications will be anonymous. The Recent sales email open date, Recent sales email clicked date, and Last engagement date properties will also not be updated.

Email clicks (Sales Hub Starter, Professional, and Enterprise only)

If you have an assigned Sales Hub paid seat and you send a tracked email from your email client or from a record, you can track clicks on links included in the body of the email. Links are tracked by appending tracking to the end of any hyperlink included in your email. You can see click and open information in your HubSpot activity feed.

Only hyperlinked, non-URL text willbe tracked. For example, tracking willnotoccur if you type out www.hubspot.com. Even if the textwww.hubspot.comis hyperlinkedto www.hubspot.com, clicks on the link will notbe tracked. Tracked links will appear in the following format in the email the contact receives:

http://t.sidekickopen[xx].com/e1t/c../../www.hubspot.com.../

Please note: clicks cannot be tracked in plain text emails. 

The temporary redirection to the t.sidekickopen[xx].com domain is necessary for HubSpot to register and track link clicks. The link will automatically redirect to the final URL destination (e.g. www.hubspot.com) when clicked.

If you want to test link tracking, click the link from an email client and browser that does not have theHubSpot Sales extension installed; otherwise, the click notification may be suppressed. This prevents any notifications triggered by clicks on your own links, but this does not apply to other recipients of your email who may have HubSpot Sales installed.

How does HubSpot know an email has been opened?

To track emails, HubSpot inserts a one-pixel tracking image into the email after it is sent. You'll receive a real-time notification on your desktop when a contact opens the tracked email. Users with assigned Sales Hub paid seats can also track when a recipient clicks a link in the email.

Does HubSpot tell you who opened the email?

HubSpot will still notify you of the email open, but HubSpot may not be able to determine which recipient opened the email.

Can you track if an email is opened?

Email tracking notifies you when any email you sent has been opened or clicked. Email tracking software places an invisible image pixel in your emails that can detect the exact time and date an email has been opened by a recipient.

How are email clicks tracked?

The technology that stands behind email click tracking is fairly simple. A bulk email service, like SendPulse, automatically adds a tracking tag to every link in your email. Once a recipient clicks the link, the service receives data about this event and adds it to the statistics log in your account.
