I’m using AWS SES to send HTML emails that contain two hyperlinks. The intended behavior is for these links to be clicked manually by the email recipients. However, I’m encountering an issue where the links are being automatically triggered (likely by email clients or security tools that prefetch or scan URLs for safety). This is causing unintended actions on my server.

I’m currently testing a high throughput email sending application and leveraging AWS SES Email Receiving to verify successful delivery of sent emails. (Since the goal is to test sending of thousands of emails, thought that SES should handle such throughputs much better than regular email servers). Here’s what I have done so far:

I have set up a rule set for inbound emails in AWS SES.

I am using AWS node-sdk to send emails from my AWS verified SES identities. It works for one identity but not from the other. Both the identities are verified and have exactly the same configurations. I get a success message with a messageID for both of them, However, in case of one identity I receive the email in my inbox but when using the other, I don’t receive any email in my inbox.
I am the admin user so have all the permissions. Also all the 3 identities involved here (2 senders and 1 receiver) are all verified using email verification.
What could be the issue here?
