Grow your text marketing list and your email list at the same time using Attentive’s best-in-class sign-up forms. Customers can opt in to both email and text marketing in the same sign-up flow. Our integration ensures that emails automatically sync to Epsilon so that you can start sending marketing emails immediately.

Postback data

Through this integration, Attentive shares the following data with Epsilon:

Ensure that you meet the following requirements in order to set up this integration:

  • You must have an Epsilon account

Now, complete the following procedures to set up the integration.

    • Client secret
    • Username
    • Password
  • X-OUID—business unit ID from your Epsilon account
  • Message ID—ID of the welcome email message you want to use with the Attentive integration

After collecting the relevant Epsilon information, follow step 2 to complete the integration.

Step 2. Set up the integration in Attentive

Now, complete the following procedure to set up the integration in Attentive’s platform:
