# Channel Reachability

Channel Reachability shows how many users you can actually reach on each messaging channel. It focuses on permission status, so you can compare real reachability across **Mobile**, **Web**, **Email**, and **SMS**.

Use this report when you want to answer questions such as:

* Which channel currently gives me the widest reach?
* Is my reachable audience growing or shrinking?
* Which categories drive opt-in or opt-out behavior?

### Report overview

This report is useful when total audience size is not enough. You may have a large user base, but your most effective channel depends on how many users have actually granted permission.

That makes Channel Reachability a practical report for permission-aware planning. It helps you choose the right channel, review weaker consent areas, and track whether reachability is improving over time.

### Create a report

Create the report from **Reports → Channel Reachability → Create Report**.

{% @arcade/embed url="<https://app.arcade.software/share/msEiZ6Hovbw9mzNYxqbP>" flowId="msEiZ6Hovbw9mzNYxqbP" %}

1. Open **Reports** and select **Channel Reachability**.
2. Click **Create Report**.
3. Enter a report name.
4. Optionally select a segment if you want to limit the report to a specific audience.
5. Click **Save**.

{% hint style="info" %}
Leave the segment field empty if you want to track all users. Use a segment only when you want to monitor permission behavior for a specific audience, such as new users, loyalty members, or users from one region.
{% endhint %}

After the report is created, Netmera starts collecting permission data for the selected scope.

### What you see in the report

The report breaks permission data down by channel. Each tab uses the same logic, which makes channel-to-channel comparison much easier.

{% @arcade/embed url="<https://app.arcade.software/share/TI6Cfb7G9egdWzAhjbyk>" flowId="TI6Cfb7G9egdWzAhjbyk" %}

* **Opt-in Users** shows how many users granted permission on the selected channel. These are the users you can actively target.
* **Opt-out Users** shows how many users are not reachable on that channel because they never granted permission or later withdrew it.

If the **Mobile** tab shows a high opt-in count while **Email** stays lower, push may currently offer broader reach than email.

{% hint style="info" %}
The **Email** tab appears after you connect an email provider. The **SMS** tab appears after you connect an SMS provider.
{% endhint %}

### Counting logic and update frequency

The summary metrics at the top of the report update in real time. The detailed tables refresh nightly, which makes them better for day-by-day trend analysis.

The report uses **user-based counting**, not device-based counting. A user is counted as **opted in** if at least one of their devices has permission enabled. A user is counted as **opted out** only if all of their devices are opted out.

{% hint style="info" %}
If one user has three devices and only one is opted in, that user still appears as **opted in**. This keeps the report focused on reachable users instead of raw device totals.
{% endhint %}

### Trends and breakdowns

The trend charts help you understand whether permission coverage is improving, staying flat, or weakening over time.

* The **Daily Trends Graph** shows **Total Users**, **Opt-in Users**, and **Opt-out Users** across the selected date range.
* The **Bar Graph** shows the same movement in a day-by-day format, which makes sudden changes easier to spot.
* The **Daily Changes List View** shows the exact values behind the charts for closer inspection.

Use the date picker to select quick ranges such as **Last Week**, **Last Month**, or **Last Year**, or choose a custom range for a specific campaign or release window.

{% hint style="info" %}
You cannot select dates earlier than the report creation date. Data starts from the moment the report begins running.

### Category-level reachability

The category table shows opt-in and opt-out counts by message category. Categories are created under **Settings → Message Categories** and usually represent communication types such as promotions, reminders, announcements, or updates.

This view helps you understand what users are willing to receive. A category with strong opt-in usually aligns well with user expectations. A category with high opt-out may need better targeting, lower frequency, or clearer value.

### Tag and export

Use **Tag** when you want to turn the report into an actionable audience. For example, you may tag users who are opted out on one channel and then exclude them from future outreach or analyze them elsewhere.

Use **Export** when you need the data outside the platform. You can export users by identifiers such as external ID, email, MSISDN, or mobile advertiser ID, and choose either **XLSX** or **CSV**.

### How to use this report

Use Channel Reachability to plan communication based on actual permission coverage, not just audience size. It helps you pick the right channel, monitor consent health over time, and understand which categories strengthen or weaken reachability.
