NOTE:
[Starting with GitLab 13.0](https://gitlab.com/gitlab-org/gitlab/-/issues/31509), email notifications can be sent only once every 10 minutes. This helps minimize performance issues.
## Unsubscribing from emails
Users can choose to unsubscribe from receiving emails from GitLab by following
the unsubscribe link in the email. Unsubscribing is unauthenticated in order
to keep this feature simple.
On unsubscribe, users receive an email notification that unsubscribe happened.
The endpoint that provides the unsubscribe option is rate-limited.
<!-- ## Troubleshooting
Include any troubleshooting steps that you can foresee. If you know beforehand what issues
one might have when setting this up, or when something is changed, or on upgrading, it's
important to describe those, too. Think of things that may go wrong and include them here.
This is important to minimize requests for support, and to avoid doc comments with
questions that you know someone might ask.
Each scenario can be a third-level heading, e.g. `### Getting error message X`.
If you have none to add when creating a doc, leave this section in place
but commented out to help encourage others to add to it in the future. -->
