Say a voice command to invite your opted-in contacts to Saturday's open house, then let n8n check consent, draft the messages, and send SMS and email with a full audit log

n8n's case study on Flow AI Inc., founded by former software engineer and producing new-home agent Dharamjeet Patel, describes a voice command that starts an opted-in SMS and email workflow for US real estate agents. An agent can say a line such as "I am hosting an open house next Saturday, invite everyone in my contacts." ElevenLabs turns that spoken command into structured input and posts it to n8n over a webhook. Inside a self-hosted n8n Enterprise project dedicated to that customer, workflows query a Postgres database, verify opt-in status, generate personalized copy with AI, apply 10DLC and CAN-SPAM safeguards, and route messages through SMS providers or Mailgun, logging every workflow step for audits, including the outbound SMS and email. The case study does not describe a voice-call campaign or a log of call recipients. End-to-end runs typically finish in under 60 seconds. Flow AI moved each customer into an isolated n8n project after Zapier, a free Twilio number, and Mailchimp proved too siloed for opt-in enforcement and customer isolation. Lead engineer Joshua Weatherspoon describes n8n as the company backbone; Patel contrasts a week of manual 500-email and 500-text work with speaking the campaign once.

How Flow AI built a voice-controlled real estate outreach engine on n8n
n8n (Flow AI Inc. / Dharamjeet Patel) · Case study · Oct 7, 2026
First step
Export your open-house invite list and keep only contacts with documented SMS and email opt-in, then write the one sentence you would speak to launch the campaign (date, address, and channels).

Compliance note: Only message contacts with documented opt-in, honor STOP and unsubscribe immediately, follow US 10DLC and CAN-SPAM rules plus your state calling and texting laws, and keep the audit log of each outbound SMS and email your brokerage would need for a complaint review.

Suggested prompt

Written by this directory, inspired by the source. Replace the [bracketed] parts.

Open house outreach campaign. Event: open house on [DAY DATE] from [START] to [END] at [ADDRESS]. Audience: contacts in my opted-in list only. Channels: SMS and email. Draft a short SMS (under 160 characters) and a plain-text email with subject, body, brokerage name, and unsubscribe line. Before any send, require a checklist that confirms each recipient has SMS opt-in and email opt-in on file, drops anyone on a suppression list, and writes an audit row (recipient id, channel, template version, timestamp). Do not send until I approve the drafts.
