There are a couple ways to unsubscribe from email alerts and push notifications:
General Emails and Alerts: From a desktop or mobile browser, go to profile icon in the top right corner and select account settings. Then open Subscriptions. Next to each type of email, click on/off as desired. If you would like to unsubscribe from all email alerts including saved homes and saved searches, click "Unsubscribe from all" at the top of the page. At this time you cannot unsubscribe from all emails using the Zillow app.
Saved Searches Only: From the app go to Updates on the bottom menu bar, click Edit and select the search you want to unsubscribe from. Here you will see an option to toggle off Email Notifications for that search. From a desktop or mobile browser you can change the frequency of emails to instant, daily, or never. Go to My Zillow and under the Saved Searches column, click "View all". On the Saved Searches page, you will also see the option to delete or edit your searches.
Saved Homes Only: From the app select Saved Homes on the bottom menu bar. To remove a home from your list of favorites and stop receiving email alerts, click the white heart icon on the photo of the saved home you want to remove. You will see it disappear from the list and you will no longer receive email alerts about the home. If you would like to keep the home saved in your account and not receive email updates, you can unsubscribe from the email you received in your inbox. At the bottom of the email, you will see Unsubscribe from this email.
To Stop Push Notifications: From the app, please tap the "More" option in the bottom right corner, then go to 'Settings'. Here turn OFF Saved Searches, Saved Homes and App Features and Update notifications.
Please note that it can take up to 24 hours for you to be completely unsubscribed.
