Your n8n workflow can reply to a new lead before they close the tab

A lead fills out your form, and then nothing happens for hours. One agency owner put it plainly: "There were tons of leads he didnt even reply to." This play gets a personal first reply out while the lead is still thinking about you.

  1. Job: Speed to lead

    The play

    1. Add a Webhook node set to receive POST requests, and point your lead form's submit action at its production URL, so the workflow starts the moment someone submits.
    2. Map the lead's name and message into an Anthropic node authenticated with your Claude API key, and have it draft a short, personal first reply.
    3. Add a Send Email node with your SMTP credential, set the lead's address as the recipient, and send the drafted reply as the body.
    4. Switch the Webhook node from its test URL to its production URL before you go live, so every real submission actually gets answered.

    The catch

    If the webhook breaks or the API changes, replies stop going out until someone checks the execution log, so look at it weekly.
