Distribution List problem

I have a list with over 30 adresses
but when I send  a list, everybody can see the other mail adresses
I used the checkbox private, but the same problem
What must I do, that nobody can see the oher email adresses?
like BCC
thx 4 hlp

yes - don’t use the normal address input. put them into bcc

there is no bcc

go to
menu - tools - settings - mail - compose
and tick “show cc and bcc fields when composing”
then it will show up when you write an email

In email is that okay
But I a distribution list?

yes, it works also for distribution lists. i use it all the time.

Now, I used the option
Send as a mass mail
