How to send email to contacts filtered by one account field

Hello,

We want to send email from the CRM to contacts, using a complex request. I can't seem to be able to find an easy way.

From the CRM contact Module, I should be able to select contact using contacts fields but also one field belonging to their Account. I can't find a way to add a related module in the (left column) search, or is it ? O can I make the selection another way ?
Then, once we have the list of contacts, we should be able to check the one we need, and click on the Send Email in the top tool bar.

Ideas are welcome :)
