Hello! I hope all of you are healthy and safe.

I’m having a strange issue here: when I insert my bounce URL callback (Amazon SES) and save the URL changes itself like on the screenshot.

![2021-06-02_12-51](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/6/6d86d774ceb6e66619b13d4e68f907f4a5d24394.png)

Because of that, I can’t send any emails from my Mautic installation.

Does anyone have any idea how to solve that?

Thanks!

You don’t need to enter it there.  
You need to create an SNS feedback loop, and enter there!

If you use SES API, you’ll need to add
