Hi forum,

I need to blacklist several E-Mail domains in my Mautic instance. Does anyone know, if that is possible, and how it can be done? I did not find a blacklist functionality.

Thanks and best regards,  
geussn

Hi, there are no uptodate plugins that achieve this function as far as I know.  
As a workaround you can exclude domains from your segments by using filters.

Thanks joeyk!

That is a workaround I can live with. One additional question: should the text field for entering the domain just be filled with the domain name, e.g. [gmail.com](http://gmail.com)? Or should I use % before?

Best regards,  
Stefan

Hi @geussn , if you use ‘like’ then no % is needed.  
You can also use ‘equals’, which is lot better, it takes less MYSQL resources.
