New feature: set reply-to email in mailings
Current The reply-to address in mailings sended from chasse can't be set, the default From address is used. It would be nice to be able to specify a different address also.
Proposed Reply-to address can be specified for any journey step when sending mail. This is optional, it will fallback to the default if not specified.
Use-case
Some journey mails are sent with a real person's email address in the From: header, in order to have a personal touch. Other mails are sent with another person address (who is responsible for that campaign, journey). The organization welcomes people's replies to their emails, however if they click reply in their mail client, it is sent to the default email address (as that is in the Reply-To: header) and ends up in a wrong email account where it can get forgotten. So the contact never gets a reply for their email resulting in a bad experience for them.
Technical
I can see this field (reply_to) is commented out, I don't know the reason for this, but I've implemented this feature and use it in production for a while now. If you think this could be an interesting feature, I'm happy to submit a PR.
