Set up a Mailhook

Create a Mailhook address

Addresses are scoped to your account, not to a single workflow — any workflow you own can use one.

Wire it to a trigger

In a workflow, add an Email trigger and select the Mailhook address. Narrow what actually fires the workflow with:

• Only from / Never from — sender allow/block lists
• Subject contains — substring match on the subject
• Observe follow-ups — also fire on replies in the same thread

Trigger data is available downstream as trigger.from, trigger.subject, trigger.text, and similar fields.

Manage addresses

From Settings → Mailhooks, each address can be copied, toggled active/inactive, or deleted. Mail sent to an address that no longer exists is silently ignored, not bounced.

Send or reply from a workflow

Add a Send Email step to send new mail or reply from one of your addresses — including threading a reply against the message that triggered the run, so recipients see it in-context rather than as a new thread.
