# Pulse
> You can track every lead action, from email opens to meeting bookings.
## What is Pulse?
Pulse is a feature that **collects and connects all activities of leads and customers into a single timeline**.\
You can view actions that occur across various touchpoints (such as emails, documents, meetings, forms, and web pages) at a glance.
With this feature, you can easily check the following information.
* Who opened which emails and which links were clicked
* Which documents or forms were viewed and how long users stayed
* Whether the meeting scheduler was visited and whether it led to an actual booking
* Whether an anonymous visitor was later converted into an identified contact
This allows you to **capture lead interest signals without missing them and connect them to actions at the right time**.

## Sources of user activities collected by Pulse
Pulse collects user activities generated from the following sources.
### 1. Viewing [Documents](/docs/docs)
The following document related activities are tracked.
* Which documents were viewed
* How many pages (slides) were viewed
* Time spent on each document and page
* Clicks on links within the document
* Email submission after viewing a document
This makes it possible to understand not just whether a document was viewed, but how deeply it was read.
#### Anonymous document tracking
* Visitors who do not enter an email address are recorded as anonymous visitors.
* Document viewing activities that occur in the same environment are accumulated under a single anonymous visitor.
* When an identifiable action such as email submission or link click occurs later, the anonymous visitor’s activity history is automatically linked to the identified contact.
### 2. Email opens and link clicks from emails sent via Relate / Spread
#### 2.1 Campaigns, automated campaigns, and sequences
After emails are sent, the following email related activities are tracked based on recipient responses.
* `opened`: Email opened
* `clicked`: Link clicked within the email
* `bounced`: Email bounced
* `rejected`: Delivery rejected
* `unsubscribed`: Unsubscribed
Detailed explanations of event statuses can be found in the [Status](/docs/metrics#상태status-종류와-의미) guide.
Icons make it easy to distinguish which type of email the activity came from.

#### 2.2 1:1 emails sent within Relate
The following criteria apply for tracking responses to 1:1 emails.
* Standard 1:1 emails are tracked **only when there is a single recipient**, including to / cc / bcc.
* When using Gmail integration, individual tracking is available for each recipient.
### 3. Visiting the [Meeting Scheduler](/docs/meetings) page
The following activities on the meeting scheduler page are tracked.
* `viewed meeting scheduler`: Visited the meeting scheduler page
* Time spent on the meeting page
* `scheduled meeting`: Meeting successfully scheduled
This allows you to distinguish between simple visits and actual meeting conversions.
### 4. Visiting the [Forms](/docs/forms) page
The following activities are tracked during form page visits and submissions.
* `viewed form`: Visited the form page
* Time spent on the form page
* `submitted form`: Form successfully submitted
Form submission events can be used as a key point of lead conversion.
### 5. Website page visits
By installing a tracker code on your website or landing pages, page visit history can also be viewed in Pulse.
For example, you can track:
* Which pages were visited before submitting an inquiry form
* Which content was viewed immediately before conversion
This makes it possible to understand the full pre-conversion journey.

## Viewing Pulse by individual lead
In addition to the overall timeline, Pulse allows you to **view all activities collected for each individual lead (contact)**.
When you click a specific lead on the Pulse page, you are taken to that lead’s contact page, where all related activities are displayed in chronological order in the `Pulse` tab.
On this screen, you can easily check the following.
* Which emails were opened, when, and how many times
* Which links were clicked
* Whether documents, forms, or meeting pages were visited
* Which activity occurred most recently
This allows you to quickly understand which content an individual lead is repeatedly engaging with and what stage they are currently in.

## What you can do with Pulse
Each user activity recorded in Pulse can be used as **a basis for automation and follow-up actions**.\
This makes it possible to quickly connect lead interest signals to actual conversions.
### Use cases
* Identify leads who viewed a specific document multiple times and connect them to follow-up campaigns or sequences
* Follow up with leads who opened emails but did not reply
* Identify high-conversion content by analyzing pages with long dwell time
* Track when anonymous visitors convert into identified contacts
Based on these activity signals, you can take the following actions.
* Trigger [Spread | Emma](/docs/emma-intro) automations based on specific activities
* Immediately add engaged leads to lists
* Quickly identify leads with high conversion potential
This allows you to capture moments of interest without delay and convert them into leads,
while continuously analyzing post-conversion behavior to improve high performing paths and content.
