Reply to an email
POST
/api/emails/{emailId}/reply
Create and queue a reply to an inbound email. Mailisk derives the reply recipient, sender namespace, and threading headers from the source email, defaults the subject to Re: {original subject}, and requires either html or text content. Attachments can be included by passing base64 encoded file bytes in attachments[].content_base64; use application/octet-stream when the file should be preserved as a downloadable attachment. Replies sent only to same-namespace recipients do not consume outbound usage because they are counted as inbound email when delivered.
