Resend Validation Email (Optional)

You can use email to validate that you own or control a domain. Each email contains a validation token that you can use to approve a certificate request. However, because the validation email required for the approval process can be blocked by spam filters or lost in transit, the validation token automatically expires after 72 hours. If you do not receive the original email or the token has expired, you can request that the email be resent.

Resend Email (Console)

Select the check box for the pending certificate, choose Actions, and then choose Resend validation email. If the 72-hour period has passed and the certificate status has changed to Timed out, you cannot resend validation email.


The preceding information applies only to certificates provided by ACM and only to certificates that use email validation. Validation email is not required for certificates that you imported into ACM.


Resending validation email applies only to certificates that use email validation, not DNS validation. For more information about DNS domain validation, see Use DNS to Validate Domain Ownership.

Resend Email (CLI)

You can use the resend-validation-email command to resend email.

aws acm resend-validation-email --certificate-arn arn:aws:acm:region:account:certificate/12345678-1234-1234-1234-123456789012 --validation-domain


The resend-validation-email command applies only to ACM certificates for which you are using email validation. Validation is not required for certificates that you have imported into ACM or for private certificates that you manage using ACM.
