As a peer reviewer, you can access and manage your open and past peer reviews from Snapp under Reviewer Dashboard (login required). This approach also works if the link from your peer review invitation email did not work.
You can also access it via the starting page of your Springer Nature Profile where you will need to login and navigate to "Your Research". On the bottom of the page, you will see the segment "Roles and contributions”, where you can select the "Reviewer Dashboard".
In the "Reviewer Dashboard", you can select from the tabs "Invitations", where you can see your pending decisions and your declined invitations, and "Reviews", where you can see your active, completed and expired reviews.
If you would like to obtain a confirmation (certificate) for your Springer Nature journal peer review via SNAPP, please check Peer-reviewer certificates on SNAPP.
Please note that the email address you are registered with under your Springer Nature Profile website needs to match the email used in your review invitation email.
For peer reviews under Editorial Manager, please login to the Editorial Manager via “Reviewer Login”.
