# Einstein Engagement Frequency FAQs

Find out how Journey Builder access affects Einstein Engagement Frequency use. And get informed about what happens to your older send frequency data after you upgrade to the latest Einstein Engagement Frequency experience.

- **[To Use Einstein Engagement Frequency’s Updated Version, Do I Need Journey Builder?](https://help.salesforce.com/s/articleView?id=mktg.mc_anb_eef_faq_1.htm&release=264.0.0&type=5)**  
    Yes. Journey Builder must be provisioned in accounts that plan to use the updated Einstein Engagement Frequency app. Find account provisioning information in the Journey Builder Prerequisites.
- **[Does Updating to the New Version of Einstein Engagement Frequency Remove My Old Data?](https://help.salesforce.com/s/articleView?id=mktg.mc_anb_eef_faq_2.htm&release=264.0.0&type=5)**  
    Yes. Updating the app removes older data used by Einstein Engagement Frequency. Specifically, the two data extensions populated by Einstein Engagement Frequency, called Einstein\_MC\_EMAIL\_Frequency\_Undersaturation and Einstein\_MC\_Email\_Frequency\_Oversaturation, are deleted. No other data extensions are deleted or modified.
- **[Can Einstein Predict Engagement Frequency on a Segment or Brand Level?](https://help.salesforce.com/s/articleView?id=mktg.mc_anb_eef_faq_3.htm&release=264.0.0&type=5)**  
    No. Engagement frequency predictions are only available at the contact level for contacts in your business unit.
- **[Are Saturated Contacts Suppressed from Email Sends?](https://help.salesforce.com/s/articleView?id=mktg.mc_anb_eef_faq_5.htm&release=264.0.0&type=5)**  
    No. Einstein Engagement Frequency identifies segments and groups your contacts by segment, but you control sending. To prevent saturated contacts from receiving unwanted messages, remove or reduce messaging activities in their journey path.
- **[Does Einstein Predict Engagement Frequency for Mobile Products?](https://help.salesforce.com/s/articleView?id=mktg.mc_anb_eef_faq_4.htm&release=264.0.0&type=5)**  
    Yes. Einstein Engagement Frequency supports email and MobilePush.
