Hello,
I have been sending newsletters with MailWizz and Amazon SES. I received a notice from MxToolbox saying that I was blacklisted by SURBL. Then I went to the website of SURBL and requested a removal. They sent me an email as follows:

A consultant told me that "SURBL checks spam URLs only, so check if you have added any spam URLs to the email content.". So I tried to check the source code of the email, I did not find `mail.matrixlead.com/campaigns/`.
Does anyone know 1) how could I check if `mail.matrixlead.com/campaigns/` was indeed inserted in my newsletter? 2) how could I remove that? 3) Are there any other reasons why SURBL blacklisted me?
Thank you
