Indeed, the IMAP node is what’s called a trigger node in n8n. Meaning it can be used to start a workflow when something happens, but it doesn’t typically do much afterwards.
Most other trigger nodes have an equivalent “regular” node, but that’s not the case for the IMAP node I am afraid. You might want to leave a vote on the respective feature request though: IMAP Inject & Move Message
Aha, I see. That’s a bit of an issue for me. I guess I’ll have to look into implementing this node myself somehow or getting it commissioned. I’ll take a look at the docs, however, any particular resources you would recommend?
I’m using N8N Cloud, is it even possible to use custom nodes there?
Lastly, if switching email providers would be an option, you could consider using Gmail. n8n’s Gmail node would let you add (and remove) labels from email thread (with labels being Gmail’s alternative to folders).
