**Your software**  
My Mautic version is: 4.4.1  
My PHP version is: 7.4.29  
My Database type and version is: 10.3.34-MariaDB-0ubuntu0.20.04.1

**Your problem**  
My problem is:  
I see some errors in the log and I suppose what is causing this… In Mautic I do not feel (yet) no side effect, but I suppose are the only 200 contacts that I have at the moment.  
When more contacts are, I suppose the errors will have an impact on the performance of my mautic instance.

These errors are showing in the log:  
many like these:  
`[2022-11-12 16:20:04] mautic.NOTICE: PHP Notice - Undefined index: Type - in file /var/www/html/m/app/bundles/EmailBundle/Swiftmailer/Amazon/AmazonCallback.php - at line 147 {"payload":{"notificationType":"Delivery","mail":{"timestamp":"2022-11-12T16:20:03.885Z","source":"\"=?UTF-8?B?SW9udcWjIE9qaWPEgw==?=\" ","sourceArn":"arn:aws:ses:eu-central-1:945827138349:identity/here_is_my_email_address","sourceIp":"88.numbers.124","callerIdentity":"MauticAPI2SES","sendingAccountId":"94numbers49","messageId":"010701846ca416ad-bf67f64a-db8b-4b58-94d3-2ed8843434b8-000000","destination":["email_address_of_contact"]},"delivery":{"timestamp":"2022-11-12T16:20:04.442Z","processingTimeMillis":557,"recipients":["email_address_of_contact"],"smtpResponse":"250 2.0.0 OK 1668270004 f19-20020a05600c44d300b45686534bbsi3113261wmo.131 - gsmtp","remoteMtaIp":"66.102.1.26","reportingMTA":"b224-1.smtp-out.eu-central-1.amazonses.com"}},"type":"Delivery"} {"hostname":"ubuntu-2gb-nbg1-1","pid":1577853}`

`[2022-11-12 16:20:04] mautic.WARNING: Received SES webhook of type '' but couldn't understand payload [] {"hostname":"ubuntu-2gb-nbg1-1","pid":1577853}`

Steps I have tried to fix the problem:  
As I remember that in Amazon SES I chosen one setting that was looking not quite right to me, I went again there and change it:

- the errors comes with **1** activated (see picture)
- changed to **2** - I suppose this is the right setting, as I do not need a **delivery feedback** - as understood from the error logs, Mautic cannot process this sort this answer.

Please a quick confirmation that my change (to 2) is the right setting.  
Thank you and regards from Germany
