Instant Lead Response: Send a Welcome Email & Slack Alert in 3 Seconds with Make.com

TUTORIAL 1 Make.com 30 min setup No code required Free tier compatible
⏱️

30 minutes to build. Saves 3+ hours per month.

Every lead gets a personalised email within 3 seconds. Your team gets a Slack alert with full details. You do nothing.

The Problem

A lead fills out your website form at 2pm. You see the notification at 4pm. You draft a welcome email at 4:15pm. By then, the lead has already signed up with your competitor who responded in 30 seconds.

Studies show responding within 5 minutes makes you 21x more likely to convert a lead. Most businesses respond in hours. This automation responds in 3 seconds.

What You'll Build

A 5-step Make.com scenario that:

  1. Catches every form submission the instant it happens via webhook
  2. Sends a personalised welcome email using the lead's name and enquiry details
  3. Alerts your team on Slack with the lead's full info so they can follow up
  4. Runs 24/7, including weekends and holidays — never misses a lead

Step-by-Step Guide

1

Create a New Scenario in Make.com

Log into make.com and click "Create a new scenario" in the top right. This gives you a blank canvas to build your automation.

You'll see a single empty circle in the middle — this is where your first module goes. Click the "+" button to add your first module.

Pro tip: Name your scenario something descriptive like "Website Lead → Email + Slack Alert" so you can find it later.
2

Add a Webhook Trigger

Search for "Webhooks" in the module list and select "Custom webhook". Click "Add" to create a new webhook.

Give it a name like "Website Contact Form" and click "Save". Make.com generates a unique URL — this is the URL your website form will POST data to.

Copy this webhook URL — you'll paste it into your website form's action attribute or form handler. The URL looks like: https://hook.eu1.make.com/abc123...

Pro tip: Click "Re-determine data structure" and submit a test form to teach Make.com what fields to expect (name, email, message, etc.).
3

Add the Email Module

Click the "+" after the webhook module to add a new step. Search for your email provider:

Connect your email account, then configure the fields:

Pro tip: Keep the email short, warm, and specific. Mention what they enquired about. "Hi Sarah, thanks for your question about our enterprise plan" converts 3x better than a generic "Thanks for contacting us".
4

Add the Slack Alert

Add another "+" module after the email. Search for "Slack" and select "Create a Message".

Connect your Slack workspace, then configure:

Example Slack message:

🔥 New Lead Alert!
Name: {{name}}
Email: {{email}}
Message: {{message}}
Time: {{timestamp}}
Pro tip: Add an @channel mention for high-value leads. You can add a Router module before Slack to filter by lead source or enquiry type.
5

Connect Your Website Form

The final step: point your website form at the Make.com webhook URL. How you do this depends on your form setup:

Once connected, go back to Make.com and click "Run once". Submit a test form. You should see the data flow through all 3 modules — webhook received → email sent → Slack alert posted.

When it works, click "Activate" (the toggle in the bottom left) to make it run automatically 24/7.

Pro tip: Make.com's free tier gives you 1,000 operations per month. A 3-module scenario uses 3 operations per form submission — that's ~333 leads per month for free.

What Happens Now

Every time someone fills out your form: they get a personalised email in under 3 seconds, your team gets a Slack alert with their full details, and you didn't lift a finger. Runs 24/7, weekends, holidays, 3am — always.
