Right now (Sentry 8.17.0), you can only subscribe to all alerts for a project in your account’s notification settings. It would be great being able to specify, which alerts you want to subscribe.
An example: We use one sentry project for both frontend (Javascript-SPA) and backend (API) of an application since errors of both can be related. But there are people only working on the frontend or on the backend. We’d create specific alert rules for both applications and each developer could then decide whether she wants to be alerted about frontend, backend or both types of errors.
