Please add the ability to change / add email headers as this is a very important option when sending emails and many headers are RFC standards Message Headers
In addition, headers make it possible to add a link to unsubscribe in one click “Header List-Unsubscribe”
Thank you for your attention, I hope for a quick solution to this issue.
Hey @maxmarines welcome to the community. Will be added to our backlog.
Hi @RicardoE105 is there any update on this? I feel this feature is very critical to automating email flows.
Hi team.
RicardoE105 - Was there any updates on this?
Hi Ricardo, 2 years in backlog.. Please, can we have any news? This is very important feature, also about secutiry compliance
if anyone still asking about this, i had to build a new custom node like Send Mail with an option to add any additional email header you want, i hope it get approved as a community node ASAP 
Yes I’d love the option. Replies don’t stay connected without custom headers. That would be a big fix.
