Sending a mail to filtered and selected companies

hi,

here is the scenario:
i am searching for companies in my region. After filtering I would like to select 3 companies and will have the possibility to write them a email.
But I wouldn´t write to each company a email by myself. I would like to select these 3 companies, write one email and send it to all 3 company.
Do you understand my request?

Regards,
Jürgen
