By default, the email messages that Amazon Cognito sends to users in your user pools come from no-reply@verificationemail.com. Complete the following steps to specify a custom FROM email address to use instead of no-reply@verificationemail.com.
1. In the Amazon Cognito console, choose Manage User Pools, and then choose your user pool.
2. In the navigation pane, under General settings, choose Message customizations.
3. Scroll to the bottom of the page. Under Do you want to customize your email address, select the plus sign to the left of Add custom FROM address to display the custom options. Then, do the following:
• In the SES Region list, verify that the correct Region is selected.
• In the FROM email address, select the SES verified email address that you want Amazon Cognito account verification emails sent from.
4. Choose Save changes.
