Description
Who It's For
Sales teams, agencies, and service businesses that follow up with inbound leads via email and want to automate the entire sequence without losing the personal touch.
How It Works
Webhook receives the new lead form submission
Configure Variables node sets your sender name, email, company name, reply detection email, and wait time in one place
OpenAI writes a personalized first follow-up email based on the lead's inquiry details
Gmail sends the first email
Wait node holds the workflow for 48 hours
Gmail searches the inbox for any reply from the lead
If the lead replied: Slack notifies your team and Google Sheets logs the reply status, name, email, and timestamp
If no reply: OpenAI writes a second follow-up from a different angle and Gmail sends it
Set Up Steps
Update the Configure Variables node with your sender name, email, company name, and reply detection email
Connect your Gmail, OpenAI, Slack, and Google Sheets credentials to each node
Create a Google Sheet with columns: Lead Name, Email, Reply Status, Date
Activate the workflow and test with a webhook POST request
Requirements
Gmail account with OAuth credential
OpenAI API key
Slack workspace with a notifications channel
Google Sheet set up for reply logging
