You can personalise your alerts at any time by logging into your account:
On the App : Me → My Alerts → Items I'm looking for
On the website : My Account → Alerts → Items I'm looking for → Setup
To edit the frequency of alerts you've already created, select the alert concerned from the list and then select your notification preferences.
💡 Good to know - You can choose to receive alerts every day, or set up the frequency for each individual search. You can also choose how you would like to receive alerts - via email, mobile notification, or both!
