I am using Amazon SES to send email. I have sent emails with the following addresses:

– **From** Address: Email Alias <me@domain>.

– **Reply-To**: me+{id}@domain.

– **To**: someone@domain.

While testing in the Gmail app/web, I’ve encountered an issue. When attempting to reply, the **From** address is being populated instead of the **Reply-To** address in the **To** field of the reply email. Additionally, the Email Alias is not appearing in my inbox. Interestingly, this behavior is observed only for the FIRST email received from this domain in Gmail’s web/app. Subsequent emails do not exhibit this issue. However, when using different email service providers such as Outlook or Mail (Apple), the aforementioned features work correctly from the first email itself.

I’ve checked the source code of the emails received in the Gmail web UI, and it contains the **From** address with the Email Alias and the **Reply-To** header as expected. However, for some reason, they are not being utilized.

Issues:

1. **Reply-To** address is not being utilized in the first email from the domain.

2. Email Alias is not displayed in the inbox for the first email from the domain.

Can someone please provide assistance?

I expect to send emails from SES with the **Email Alias** and **Reply-To** address (which is different from the **From** address) from the **first** email itself from my domain.
