Automatic sending of emails

At work there was a problem on sending greetings\invitations to exhibitions, etc. counterparties of the company.
For all that, it is desirable that every Manager will lead the database of their contacts without seeing other people's contacts, and the person responsible for mailing formed themselves email templates.
May have any free open source code and similar functionality, very preferably written in php?

free even if there is, I would still give this task to a Pro type Amazon. Well, if you only need free, don't forget to talk to your admin.
Knowing the policy of our company, third-party services, such information is not want to give away, so you need their own. Base I doubt most, most likely less than 10K recipients. - retha13 commented on October 8th 19 at 01:38
for 10K you (or your administrator) in any need to configure SPF at least. - mackenzie.Mraz23 commented on October 8th 19 at 01:41
