[MM3-users] Re: HTML header / footer template

I understand Mailman 3 doesn't want to support HTML Emails, This is perfectly legitimate, sadly however, This is a requirement of my client, Which is in this case the Ministry of Education of Israel.

This is not the first time a client of mine requires this, This is also was required and implemented in Mailman 2 couple of years ago by some other client (big college).

So starting to implement it, I found this article: https://blog.hubspot.com/marketing/plain-text-vs-html-emails-data

which also claims that HTML Emails is prefered by many users (although I understand the problematic nature of HTML Emails)

Could You give me some directions on how to go about implementing this ?

Thanks
