Iterable is an automated email tool. With Iterable, marketers can send the right message, to the right device, at the right time. Iterable supports blast, triggered and transactional campaigns, personalized templates, dynamic workflows, A/B testing and much more. Visit Website

Take your company’s email analysis to the next level by adding Iterable as a Source to Segment. We’ll automatically collect email events like Email Delivered and Email Opened, forward them to your destinations, and load them into your data warehouse.

In your favorite BI or analytics tool, you’ll be able to analyze your email campaigns in SQL or through drag-and-drop reports. And, you’ll be able to join your Iterable data with the event data you’re already sending through Segment to analyze the down-funnel effects of your emails. Learn more about how you can use Iterable with Segment.

Getting Started

If you have previously enabled sending email events via the Iterable destination during our beta (using a project write key), you do not need to create new Iterable source. Your email data will continue to flow as normal.

  1. From your workspace’s<your-workspace>/sources page, click Add source.

  2. Choose Iterable.

  3. Give the Source a nickname and a schema name. The nickname will be used to designate the Source in the Segment interface, and the schema name is the namespace you’ll be querying against in your warehouse. You can name them however you’d like, but we recommend sticking to something that reflects the Source itself, like Iterable for nickname and iterable for the schema name.

  4. The next page (“Overview”) will surface your Segment write key for Iterable. Copy this write key.

  5. To finish the setup, you’ll have to go into your Iterable account and enter this Segment write key in their integrations settings. Find the right place in Iterable by clicking Integrations > Third Party > Segment.

  6. Click Save.

  7. In Segment, click into your Iterable Source in<your-workspace>/sources. From there you’ll be able to add Destinations where you want to see email events.

That’s it! As you send emails, events will now be sent to your destinations and automatically loaded into any warehouses you have enabled.



Iterable uses our stream Source component to send Segment email events. It uses a server-side track method to send data to Segment. These events are then available in any destination that accepts server-side events, and available in a schema in your data warehouse, so you can query via SQL.

The default behavior is for Iterable to pass the userId associated with the email recipient as the userId. There are cases in which Iterable does not have an associated userId, in which case the email address will be passed in as the anonymousId.


Collections are the groupings of data we pull from your Source. In your warehouse, each collection gets its own table, as well as a tracks table that aggregates all the events into a single table.

Email DeliveredEventMessage has been successfully delivered to the receiving server
Email OpenedEventRecipient has opened the HTML message. You need to enable Open Tracking for getting this type of event
Email Link ClickedEventRecipient clicked on a link within the message. You need to enable Click Tracking for getting this type of event
Email UnsubscribedEventRecipient clicked on message’s subscription management link
Email BouncedEventReceiving server could not or would not accept message
Email Marked as SpamEventRecipient marked message as spam

Send data to Iterable

The Iterable Source works better when you also connect Iterable as an destination. With the Iterable Destination, you can use Segment to send Iterable user and event data from which you trigger email campaigns. Want to start sending website or mobile data TO Iterable?
