How to segment push subscribers with tags and segments

Before you start

• You need subscribers first. Your website must have the relaybell snippet installed and visitors must have clicked Allow. If the cards say 'No subscribers yet,' nobody has subscribed and there is nothing to manage.
• To see a real identifier instead of 'Anonymous' (and to look people up by it), your site has to set an External ID for each subscriber through the code snippet/SDK.
• To filter by tags, your website must attach tags to subscribers via the SDK or API first - otherwise the 'tag' field has nothing to match.
• To use topics, your website must offer the preference center (via RelayBell.setTopics([...]) or RelayBell.showPreferences()) so subscribers can actually pick categories.

Set it up

1. 1Open Audience from the left nav. Everything on this page fills in automatically from the subscribers your website is already collecting - there is nothing to switch on here.
2. 2Read the 'List health' card near the top for a snapshot: Active subscribers, Reachable devices, New and Lost in the last 30 days, your 30-day churn %, and how many are Dormant (no push in 60 days).
3. 3To find one person, use the 'Subscribers' card: type their External ID or subscriber ID into the box and click 'Look up' - or just click any name in the recent list below it. A panel slides in from the right with their profile.
4. 4Read the profile panel: their Subscribed/Unsubscribed status, delivered and clicked counts, Country / Language / Timezone / Joined date, their Devices, any Topics they picked, their Tags, and a recent-activity timeline. This panel is view-only - you cannot edit anything from here.
5. 5To build a group to target, scroll to the 'Segments' card and find 'New segment.' Type a name in the 'Segment name' box (a segment must have a name to save).
6. 6Pick a field in the first dropdown: country, language, url (the last page they were on), or tag (a custom label your website attaches). If you pick tag, a small 'tag key' box appears - type the tag's name there.
7. 7Pick a rule in the second dropdown: eq (is exactly), contains (includes this text), or exists (has any value at all). For eq or contains, type what to match in the 'value' box; exists needs no value.
8. 8Click 'Preview' to see 'N subscribers match' before you commit. This counts only people who are still opted in.
9. 9Click 'Save segment.' It appears in the list above with its name and creation date. To remove one, click the red 'Delete' beside it.
10. 10Optional: in the 'Topics (preference center)' card, type a category name such as 'Deals' and click 'Add' to create a topic your subscribers can choose on your site. The x removes a topic.
11. 11Optional: click 'Export CSV' on the 'Subscriber growth' card to download your whole list (subscriber ID, external ID, country, language, timezone, status, consent date, devices, tags, join date) as relaybell-subscribers.csv.

Every setting, explained

Tags vs Segments vs Topics (the key distinction)

A TAG is a fact you attach to a person (for example plan=pro or city=Delhi) - it is information about them. A TOPIC is a category the subscriber chooses for themselves (like 'Deals' or 'News'), so it is something they told you they want. A SEGMENT is a saved rule that groups people by any of that (for example 'everyone in India' or 'everyone tagged plan=pro'). Tags and topics describe people; a segment gathers them.

Segment field: country / language / url / tag

The thing your rule looks at. 'country' and 'language' come from the subscriber's browser when they joined. 'url' is the last page on your site they were seen on (great with 'contains', e.g. url contains /products/). 'tag' is a custom label your website attaches - choosing it reveals a 'tag key' box where you name which tag to check.

Segment operator: eq / contains / exists

eq means 'is exactly' this value. contains means the value includes this text (not case-sensitive) - good for partial matches. exists means the field simply has any value at all (for a tag, it means the person has that tag no matter what its value is), so no value box is needed.

External ID vs subscriber ID

The subscriber ID is the internal ID relaybell gives every subscriber. The External ID is your own ID for that person (their user or customer ID), which your website sets through the code snippet. You can look someone up by either. People with no External ID show as 'Anonymous.'

Active subscribers vs Reachable devices

Active subscribers counts people who have not opted out. Reachable devices counts the actual devices you can push to - one person can be subscribed on their phone and laptop and so count as two devices.

30-day churn

The share of your list lost in the last 30 days, measured as people lost divided by (active + lost). The number turns amber once it climbs above 5%, a sign you are losing subscribers faster than usual.

Dormant - 60 days

Subscribers who are still opted in but have not received a push in the last 60 days (and joined more than a week ago). The card hints that a win-back journey could re-engage them.
