Email field in Module not active, not in blue color

I have a custom made module with an email field (texttfield, Label Email Address) like xxxx@yyyy.com and that appears in ListView in black color and there
I cannot click on it… to jump to the Suitecrm email system to send an email.

In Accounts/Contacts the email addresss is in blue color and that is “active” so clicking it, the email system pops up.

I need this to check and mass update/sent an email to several clients, BUT not in CC: like xxx@yyyt.com; ppp@xxx.com;vvvv@zzz.com
but if possible in seperate emails, or in BCC, sothat other cannot see to whom it was sent also.
Thanks for any help
