@lambert-torres there is no queue that is kept, you would either need to look at the logs to specifically find the users during that time. Or follow the below steps.
You can resend the verification emails for newly registered users. FusionAuth provides an API endpoint for resending a user registration verification email.
https://fusionauth.io/docs/v1/tech/apis/users#resend-verification-email
Here are the steps to follow if you want to manually verify:
Use the PUT /api/user/verify-email?email={email} endpoint to request a new verification email. This will return a verificationId in the response. curl --location --request PUT 'http://localhost:9011/api/user/verify-email?email=<my_email@my_email.com>' \ --header 'Authorization: <API KEY>' \ --header 'X-FusionAuth-TenantId: <TENANT_ID>' The response should look like this: { "verificationId": "SOME_REALLY_LONG_ALPHANUMERIC_STRING" } Use the POST /api/user/verify-email?verificationId={verificationId} endpoint to mark the user as email verified via API.Please note that you need to ensure that you don't have skipVerification set to true when a user registers for an application via API and your application has verifyRegistration set to true. This can be set programmatically via the API or via the admin UI.
For more details, you can refer to the FusionAuth documentation and the FusionAuth community forum.
Please ensure that your connection to SendGrid is restored before attempting to resend the emails.
