I frequently send between 200 and 400 emails, either personally or as part of an association, and I would like to know what the real impact of these emails is.
I discovered yesterday the existence of Mail CHIMP and MailJet which are used to make mass mailings and have tracking and statistics features.
But I would prefer, if it exists, to use an open source software or, better still, an application that I would install on my computer.
Could you advise me on this matter?
With kind regards,
