Even for the most avid communicators, finding that email you sent five years ago... to just three people... is a breeze. Your list of communications can be filtered by status, topic, date and more. You can view your communication history under People > Communication Reports > Communication History.

With just a few clicks, you can narrow down your Communication History list to find exactly what you need. To filter by Communication Medium, use the icons at the top of the list: Mail Text Push Notification Personal Preference You can also filter or sort directly from the column headers. Click the icon to filter a column, or double-click any column to reverse the sort order.

Need even more control?

Use the ti ti-adjustments-horizontal icon to open the List Settings panel. There, you can filter by:

Filtering Large Lists Improves Load Time
If your list includes hundreds or even thousands of communications, applying filters will improve performance and reduce load times significantly.

See the Bigger Picture
Those with Approve permissions on this block will be able to see every communication in the system and can filter by a specific person.

View a Person's Communication History

A history of communications that have been sent to an individual can be viewed on the Person Profile page, under the History tab. This is where you'll come to find out which communications a person has received, and to view the details of those communications.

Phone Number Security in Communication History
You can set a security which allows specific people to view the SMS messages when setting up the SMS communication. But please note that the personalized communication history block does not respect SMS view access. This means that people will be able to see the SMS communication even if they do not have the security permission to do so.

View Analytics

Once you have selected a communication in the Communication History, you will have the following view.

Delivery Breakdown

Analytics show how your message moved through the system: from queue to open (or not). The states shown depend on the transport used, so you might not see every one every time.

Performance KPIs

Get a snapshot of how your message performed after sending: opens, clicks, unsubscribes and more.

Performance Chart (Time)

This chart shows how your key metrics trend over time. You’ll see rates for opens, clicks, unsubscribes and spam complaints plotted across the first 45 days after sending (or from launch to today if the message is older).

Use this view to spot patterns—for example, if clicks surge on the first day but drop off quickly, or if unsubscribes rise after a certain number of days.

Switch to the Flow option in the picker (top right) to see the same performance data, but with a different lense.

Performance Chart (Flow)

The flow view illustrates how recipients move through the stages of your message, from sent to delivered to opened and clicked. This helps you see the full recipient journey at a glance.

How to Read This Chart

The chart flows left to right. Each color represents a status, and the width of the band shows how many people reached that stage. Hover over a band to see exact counts.

For example, you might see that most messages were delivered, fewer were opened, and only a fraction were clicked. This makes it easy to gauge drop-off points and overall engagement.

Unique Opens

These charts break down who opened your message, helping you see which groups are most engaged.

Keep in mind that some people may not have gender or age data recorded in Rock, so they’ll appear in the Unknown category.

Top Email Clients

This chart shows which email apps your audience used to open your message. Knowing the most common clients helps you design messages that display well across devices.

The list includes percentages for each client, along with an Unknown category when the system can’t detect the app.

Medium Matters
Analytics vary depending on the medium you used to send the message. Email provides detailed insights like client usage, while SMS and push notifications only include basic stats such as delivery. Many metrics like Top Client apply only to email.

Analytics give you the big picture of how your message performed. Next, let’s look at the message itself:

View Message Details

By selecting the "Message Details" tab on the Communications Analytics block, you will see this view.

Email

This page shows you details related to the communication itself. Reviewing things like the subject of an email or the phone number used to send a text message can be helpful both for sent messages and for future communications that are pending.

If the communication is a draft (i.e., not yet sent) you'll also see the option to Cancel Send. Additionally, if the communication hasn't been approved, you will have the option to approve or deny from this screen.

SMS

Push

View Recipient Details

Communication is personal, and Rock makes it easy to see how each individual engaged with your message. The Recipient Details tab shows exactly who received the message and how they interacted with it as if you were there when they opened it (but not in a creepy way!). This is especially useful when you want to track opens, clicks and delivery for specific people.

You may have hundreds of recipients in a bulk email, so use ti ti-filter to sort and filter by column, or ti ti-adjustments-horizontal to add extra columns with details such as:

You can filter or sort these columns just like the main list.

And when you select a recipient, you’ll see the nittiest-grittiest details: when the message was delivered, if they opened it and whether they clicked a link.

Communication Transports Matter
The transport you use (for example, Mailgun) determines how much detail you’ll see in your analytics. Some providers offer in-depth metrics, while others only provide high-level data. For more on the differences between transports, see the Integrations article.
