Mention notification settings
It’s possible to customize your mention notifications by accessing your settings in the mobile app and the Strava website. You can choose to receive no notification, an e-mail notification, a notification in the app, or both an e-mail and notification in the app each time you are mentioned. Android users can adjust both mobile and e-mail notification preferences in the app, while iOS users can adjust mobile notification preferences in the app and e-mail notification preferences in their settings on the Strava website.
