Object and relationship campaigns
You can trigger campaigns based on changes to objects and relationships. You can target trigger data in messages and specify who should enter a campaign based on the relationship they have to objects.
Trigger campaigns based on objects or relationships
You can trigger campaigns based on changes to objects or relationships. You can trigger a campaign when:
- an object is updated (like an Account’s name was changed).
- a relationship between an object and person is added.
- a relationship is changed (like a person is no longer associated with an Account).
You can also narrow in on the audience for these campaigns. For both object and relationship-triggered campaigns, you can choose to send to:
- every person in the object or
- certain people in the object
For relationship-triggered campaigns, you can also choose to send only to the person that triggered the campaign.
Your audience cannot exceed 1,000 people each time the campaign triggers.
If it does, the people will not start a journey. You will see “Failed Journeys for Object/Relationship Campaign” in your activity log. Keep this in mind anytime you choose “Every person in the object” or “Certain people in the object” as your audience settings.

Considerations for audiences over 1,000
Object and relationship campaigns will not create journeys when a trigger event reaches over 1,000 people. If you think you might want to send to over 1,000 people each time the campaign is triggered, consider:
- Is there a better way to craft your automation? Do you actually mean to target a more specific audience or a more specific change to an object or relationship?
- If yes, adjust your campaign settings or consider a different type of campaign.
- If not, reach out to our Support team for assistance.
For example, let’s say you run a real estate marketplace. Each object is a house on sale. There are 1,100 people who have liked a house. You craft a campaign to send to all of them when the property is sold. But do you in fact want all 1,100 people to know this? How old is the listing? Have people on this list already purchased a different house since they liked the property? Is it better that only those who liked the house AND went to a showing know? Asking questions like this can help you craft a more specific campaign and ensure you reach exactly who you intend to.
Performance considerations
Imagine you have a few Account objects with 10 people related to each of them. Each Account has a lifetime_value attribute, and you have five segments and five campaigns that send messages based on an Account’s lifetime_value. Each time an Account’s lifetime_value gets updated, our system checks each of the 10 people related to that account to see if they should still belong to any of the segments or campaigns.
One little change - to a single Account’s attribute, in this case - caused us to check 100 things (5 segments x 10 people, 5 campaigns x 10 people). At this scale, that’s no problem.
But imagine you have hundreds of thousands of Accounts and most of them change every day. That can pretty quickly become hundreds of millions, even billions, of things for us to process. We know how to handle this - it’s our job! But if you ever get to an extreme enough scale, we’ll send you warning messages so you know well in advance if your account could be impacted. In very extreme situations, we might need to throttle the data we process from you - but again, we’ll always warn you long before we get to that.
Bottom line, the more segments and campaigns you have based on objects, the more you should make sure you’re targeting and updating the correct objects and relationships. For instance, instead of sending us your entire database every hour, send us only the object data we need. Of course, if you have any concerns, reach out to us and we’ll be happy to help!
Workflow actions for objects and relationships
Currently, you cannot use object or relationship liquid in any workflow item other than a message. You can reference an object in an email, but not in a Create or Update Person action, for instance.
In the future, we want to expand how you can manipulate object and relationship data within campaigns. We’re considering adding a Create or Update Object action, branching based on object or relationship attributes, the ability to query objects like you can with collections, and the ability to use object and relationship liquid in workflow actions like Send Event.

Trigger a campaign with a relationship-based segment
People enter segment-triggered campaigns when they join (or leave) a segment. But when you create a relationship-based segment, a person only joins the segment for their FIRST relationship to an object matching your criteria. Their segment membership won’t change on subsequent relationships. This means that a person will only trigger a campaign for the first relationship matching your segment criteria. To trigger a campaign for each relationship change, create a relationship-triggered campaign.
For example, imagine that you have a segment of people related to online classes, and you use that segment to trigger a campaign:
- When a person signs up for their first online class, they’ll join the segment and enter the campaign.
- When they sign up for another online class, they won’t trigger the campaign again because their segment membership didn’t change!
In this example, a person would only re-join the segment if they unenrolled from all their classes, causing them to leave the segment, and then re-enrolled in a class later.
to person)-->b{is this the first
relationship?} b-->|yes|c(person joins
segment)-->e(Person enters
campaign) b-.->|no|d(person does not
enter campaign)
Exit Conditions follow these same principles: a person won’t leave a segment (causing them to exit a campaign) until they’re no longer related to any objects matching your segment criteria.

Use an object in a segment
You can create object-oriented segmentsA group of people who match a series of conditions. People enter and exit the segment automatically when they match or stop matching conditions. on the Segments page, or when you create campaigns and newsletters. Learn more about how relationship-based segments work in campaigns.
- Go to Segments and click Create Segment.
- Give your segment a Name and a Description, and click Create Data-Driven Segment.
- Under Add condition or group, select Relationship and set a condition to Relationship to
your object typeexists.
- (Optional) you can refine your selection by clicking Refine and selecting an object-based attribute condition. For example, you might want to limit a newsletter segment based on a
countryorplan_nameattribute. - When you’re done, click Save Changes.
Now you can use your segment in newsletters or to trigger campaigns.
You cannot backfill relationships
We don’t have a concept of historical relationships in Customer.io—at least not yet. For example, a person might have joined a company several years ago, but it will appear that they only recently joined the company when you set their relationship in Customer.io.
Because you can’t backfill relationships, you should be careful when using relationship-based segments to trigger your campaigns. For example, if you want to send a welcome campaign for new employees of a company, and you relate people to the company after you set up your campaign, you may inadvertently trigger a welcome campaign for those people.
