Configuring Mass Emailing in v11

Hi, I am new to Dolibarr, and I am trying to get mass (bulk) emailing setup. My email list has around 30,000 users. What is the best way to import these contacts?

I tried to make a new Emailings and when I click the recipient’s tab, I try and upload via Emails from file. I get an error.

What does it mean `Imported file must have format email;name;firstname;other - Does this refer to the header in Excel?

There is not any helpful documentation that I was able to find online.
Thanks in advance

Hi,

I do not use this feature, but I gess that it needs a CSV file not an EXCEL
With on each line :
email;name;firstname;other

Thanks, OK I got past that part now. How can I change the email;firstname;name;other. Let’s say I want the email sent to name;other can I format these bulk emails? I know you said that you don’t use this module.

If Dollibar is similar to other php cms’s there should be a place I can edit a template and have the email say Dear {other}, thank you for blah blah blah.
Thanks if anyone can just point me in the right direction, I should be able to figure things out.
I still am not making sense of what documentation I have found.
