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 Optimizely (formerly known as Zaius) so that you can start sending marketing emails immediately. This integration also helps you keep your contact data and opt-in status up-to-date.


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

  • You must have a Zaius account

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

Step 1. Collect Optimizely information

Log in to your Zaius account and collect the following information:

  • API Key—In order to give Attentive permission to add contacts to Zaius, you need a private API Key. Navigate to Account Settings > APIs. Then copy and save your private API key in a safe location.
  • List ID—Add contacts from Attentive to a specified Zauis list by providing the List ID. Navigate to Customers > Lists and locate the List ID. Note the following about the List ID:
    • It should not contain whitespaces. For example: hello_1 is valid and hello 1 is not valid.
    • You can add to multiple lists using a comma-separated list. For example: hello1, hello2 posts to each of the two lists hello1 and hello2.

Step 2. Set up the integration in Attentive

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

  1. Navigate to the integrations setup page and select Zaius.
  2. Enter the following details that you previously collected in Step 1:
    • API Key
    • List ID
  3. Click Set up integration. Your Zaius account is now connected to Attentive.
