Vero Source

Good to know: Event Cloud source

The Vero Source is an event source. This means that it sends data as events, which are behaviors or occurrences tied to a user and a point in time. Data from these sources can be loaded into your Segment warehouses, and also sent to Segment streaming destinations. Learn more about cloud sources.

This source is supported in US data processing regions.

The Vero source is only supported in workspaces configured to process data in the US region. Workspaces configured with data processing regions outside of the US cannot connect to this source. For more information, see Regional Segment.

Vero is an email marketing tool that lets you set up automated emails to your users that get sent after they’ve completed certain actions. Visit Website

Take your company’s email analysis to the next level by adding Vero as a Source to Segment. Segment automatically collects 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 Vero data with the event data you’re already sending through Segment to analyze the down-funnel effects of your emails. 

Getting Started

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

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

  2. Choose Vero.

  3. Give the Source a name and add any labels to help you organize and filter your sources. You can give the source any name, but Segment recommends a name that reflects the source itself, as this name autopopulates the schema name. For example, the source name Vero creates the schema vero.

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

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

  6. Click Save.

  7. In Segment, click into your Vero 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. 



Vero 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 using SQL. 

The default behavior is for Vero to pass the userId associated with the email recipient as the userId. There are cases in which Vero 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. 

Collection Type Description
Email Sent Event Message has been sent from the Vero servers
Email Delivered Event Message has been successfully delivered to the receiving server
Email Opened Event Recipient has opened the HTML message. You need to enable Open Tracking for getting this type of event
Email Link Clicked Event Recipient clicked on a link within the message. You need to enable Click Tracking for getting this type of event
Email Unsubscribed Event Recipient clicked on message’s subscription management link
Email Bounced Event Receiving server could not or would not accept message
Email Marked as Spam Event Recipient marked message as spam

Send data to Vero

The Vero Source works better when you also connect Vero as a destination. With the Vero Destination, you can use Segment to send Vero user and event data from which you trigger email campaigns. Want to start sending website or mobile data to Vero? Head on over to our Vero destination docs.
