Hi @meadow, welcome to the community!
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
