Add "In-Reply-To" header on "Send Email" (SMTP) node

The idea is:

Add the headers “In-Reply-To” and “References” to Send Email (SMTP) node, to allow sending emails as replais to recieved emails.

My use case:

I want to reply an incoming email from n8n itself with an automated message. Now I just add "Re: " at the beggining of the subject, and mdoern email clients like Gmail treat this as a reply. But it is not the best way to do it, as it is very superficial. A better way to do it is to add the email ID (which is delivered to me on the Recieve email via IMAP node) at the “In-Reply-Tio” and “References” headers on SMTP, but this is not possible on the SMTP node on n8n.

Any resources to support this?

Very interested in this. With the AI capabilities this is a must nowadays.

The Send Email node already has an option for reply-to, but not yet for references:

Still no solution to set the In-Reply-To header so that a clean e-mail thread can be kept during conversations? :frowning:

There is already a PR for this (open since one year): feat: add in-reply-to and references to reply emails by jmrobles · Pull Request #9346 · n8n-io/n8n · GitHub

I have made a custom node that allows you to add custom headers to SMTP emails.

The README includes instructions on replying to email threads.

I also need to set the referrences header. the impact for n8n usage would be great. n8n should helps us automate stuff. unfortunately automating e-mail messaging is not possible in a good way with the existing nodes. the better-send-mail node is not available in the cloud hosting scenario, so that I cannot automate my e-mails. @n8n more automations means more transactions :wink:

I created a PR to add this feature: feat(EmailSend Node) Add In-Reply-To and References header support by martijngastkemper · Pull Request #38576 · n8n-io/n8n · GitHub. This works for my use case, but I’m curious to know whether it works for others as well.
