SES Verified Identities: Emails vs Domains

Does anyone know if it is best to now remove the verified email addresses which I previously setup under the now verified domain

This depends on your use case. When you verify a domain, you can send from any_address@verified-domain.com, but verified email address is limited to sending only from that address. For simplicity, you can remove verified email after you verify a domain

Is there an difference in behavior by SES if an email address is both a verified email address and also under a verified domain?

There are some differences. Please review this article

Hi Guys, I want to ask a new question related to this topic. Thanks for your reply in advance.

There are 2 verified identities.

1. example.com as domain identity type
2. no-reply@example.com as email address identity type.

When I send emails through Amazon Simple Email Service (SES), the emails come from no-reply@example.com. But I also want to send emails from no-reply-stage@example.com. It does not work.

no-reply-stage@example.com is not a verified identity. example.com has already been defined as a verified domain. In this case, I expect the new e-mail address (no-reply-stage@example.com) to send e-mails successfully.

Other case, There is a verified domain identity as mydomain.com. When I send emails through Amazon Simple Email Service (SES) with the address no-reply@mydomain.com, it also does not work.
