# ACM Certificate Renewal

## Overview

ACM [Email](https://docs.aws.amazon.com/acm/latest/userguide/email-validation.html) certificates are valid for 13 months (395 days). To be renewed, email-validated certificates require action by the domain owner. 

ACM begins sending renewal notices 45 days before expiration, using the domain's WHOIS mailbox addresses and to five common administrator addresses. 

The notifications contain a link that the domain owner can click for easy renewal.‌

## Examples

### Renew Email

AWS sends an Email requesting to renew the ACM Certificate, to validate the renewal, simply click on the link "Amazon Certificate Approvals".
