How can I send a new tariff to 50-100 clients? I only have mozilla thunderbird, do I have to send them one by one?
I want to the messages appear like that:
subject: ...
from: ...
to:
client@hisorheremail.com
---
static text in emails body
...
Right now, I can only get that with bcc:
subject: ...
from: ...
to: undisclosed receipts;;
---
static text in emails body
...
The email or name of client is not in anywhere. So this is bad for me. What can I do?
