Omnichannel - receive and reply to an email


I’ve been looking at the docs and how rocketchat interacts with emails (particularly omnichannel) isn’t clear to me. I would like to receive emails through the omnichannel and possibly respond to such emails. Now, I am aware that I can forward emails through a webhook and that will be made possible through mail providers (e.g. sendgrid) and I’ve done this with other services so this is not a problem. Will it be possible to reply to the email once it comes into rocketchat? Has anyone integrated emails and has any ideas or a pointer in the docs that I can use. For context, my installation is okay and I am able to send and receive sms messages via twillio without a problem. My goal is to add the second channel (i.e. email) hence this question. Any help on this will be much appreciated.
