I am not sure what your experience with other publication editors has been thus far, but it is a shame to hear that you feel your voice would not be heard (ie, that feedback would not be taken on board and that changes would be made).

We do mention the use of CTAs in our 'Write For Us' guide that is available via the navbar on the publication home page.

The CTA we deploy, as you will be aware, informs readers of the other '...in Plain English' publications, along with our email address so that interested readers can get involved in writing for our publications.
