  • The verified identity is new and is in sandbox
    When you first starts using Amazon SES, their account is in the Amazon SES sandbox. In the sandbox, you will have full access to the Amazon SES API and SMTP interface, with some restrictions on sending speed and volume.
    For information about moving out of the sandbox, you can refer to the following article

  • The domain and SMTP have been configured in different regions
    While adding your domain in AWS SES and subsequently configuring it in Mailmodo, you need to ensure that the SMTP Server is configured in the same region as your verified domain. If not, they need to be re-configured in the same region.

Instead, a 16-character password needs to be generated from the Google Account settings and entered in the SMTP Password field.
Refer to the following guide for getting steps on how to generate the 16-char password in Google settings.
