Sending email via SES without SMTP

Question

**Sending email via SES without SMTP
**I would like to know if we can send emails via SES using a KEY - SECRET and REGION instead of using SMTP.
If this is the case, then is it possible to Secure it by limiting the use of the API from a specific IP Address ( NAT Gateway)
Million of thanks

Answer

Yes, you can send email using a key/secret for an iam user rather than via the smtp.

Here are sample policy permissions:  
https://docs.aws.amazon.com/ses/latest/dg/control-user-access.html.

And here is the api/cli reference, different language references are linked at the bottom:  
https://docs.aws.amazon.com/ses/latest/APIReference/API_SendEmail.html

I've never tried setting the source ip condition for sending email in a policy, but i'm not aware of any reason why it shouldn't work. Example permissions are here:
