Emailing customers

[Eugene1994]

Hi,

I am struggling to edit my marketing campaign. I want to send emails to my subscribes via the marketing campaign page. Every time I select 'edit marketing campaign' it asks to enable cookies. When I select enable cookies an error message appears:

There’s no page at this address

Check the URL and try again, or use the search bar to find what you need.

I need support to resolve this please?
