General troubleshooting tips
Check the current health of the ecosystem
You can check the Email Alert API Technical dashboard to monitor if emails are going out.
Check that Notify sent the email
Log in to the Notify account by going to https://www.notifications.service.gov.uk.
The login credentials are in the 2nd line password store under
govuk-notify/2nd-line-support. Two-factor authentication links for logging in are
sent to the 2nd line email address.
Click "GOV.UK Email" to visit the dashboard, then click on "emails sent", which will take you to a form where you can search by email address.
Check the courtesy copy inbox
A courtesy copy of every email sent from integration, staging and production is available in the 'govuk-email-courtesy-copies' Google Group. Integration and staging emails have a subject prefixed by the environment name.
Courtesy copies are sent separately to normal emails. Therefore, it is not safe to rely on the courtesy copy Google Group to guarantee that emails are being sent to subscribers, and instead a better test is to subscribe yourself and check that emails arrive.
