MessageRejected ☁️ AWS

SES MessageRejected: Email address is not verified. The following identities failed the check in region

SES refused to send because the From address/domain isn’t verified — or the account is still in the SES sandbox, where recipients must be verified too.

Seen on: AWS

Meaning

SES requires verified identities per region. In sandbox mode you can only send to verified addresses, which surprises people the first time a real user signs up.

Common causes

  • From address/domain not verified in this region
  • Account in SES sandbox and recipient not verified
  • Using a different region than where the identity was verified

⚡ Quick fix

  1. Verify the domain (DKIM) in the sending region
  2. Request production access to leave the sandbox
  3. Configure the SDK with the SES region you verified in

Detailed fix by platform

AWS CLI

  1. bash
    aws sesv2 get-account --region eu-west-1 --query ProductionAccessEnabled
aws sesv2 create-email-identity --email-identity example.com --region eu-west-1

How to diagnose

  1. Identity — Verified in this region?
  2. Sandbox — ProductionAccessEnabled?
  3. Recipient — Verified (sandbox)?
