3 Follow-Up Scenarios to Automate

New Lead Inquiry

Someone fills out your contact form or calls. Send an immediate response, then 2 more follow-ups over 5 days.

Website Visitor

Someone visits your site but doesn't convert. Send an email 24 hours later asking if they have questions.

After Purchase/Service

Customer completed a purchase or service. Send thank you email immediately, then a check-in 7 days later.

5-Step Tutorial: New Lead Inquiry Follow-Up

We'll use the most common scenario: automating follow-up when someone fills out your contact form.

1

Map Your Follow-Up Sequence

Decide how many emails you'll send and when. Here's the template we recommend:

  • Email 1 (Immediate): "Thanks for reaching out—here's what happens next"
  • Email 2 (Day 2): "Quick check-in—do you have any questions?"
  • Email 3 (Day 5): "Last chance—let's schedule a time to talk"

Why this timing? Email 1 closes the loop. Email 2 catches people who are still thinking. Email 3 creates urgency.

2

Write Your 3 Follow-Up Emails

Copy-paste these templates and customize for your business:

Email 1 (Send Immediately)

Email 2 (Send 2 Days Later)

Email 3 (Send 5 Days Later)

3

Set Up Automation Trigger in HubSpot

In HubSpot Free (or Mailchimp), here's how to connect the dots:

  • Create a new contact form or link your existing form to HubSpot
  • When form is submitted, automatically create a new contact
  • Trigger an automation workflow on form submission
  • Add your 3 emails to the workflow with timing (immediate, +2 days, +5 days)
  • Save and activate the workflow

Most tools use a visual "workflow builder" where you drag and drop emails into a timeline. It's easier than it sounds.

4

Test Your Automation

Before you go live, test it:

  • Submit your contact form as a test (use your email address)
  • Verify Email 1 arrives immediately (within 5 minutes)
  • Check that Email 2 is scheduled for 2 days from now
  • Confirm Email 3 is scheduled for 5 days from now
  • Make sure the contact appears in your CRM

If anything fails, troubleshoot before activating for real customers.

5

Add a Human Touch Checkpoint

Automation is great, but humans still close deals. Add a manual task:

  • Set a task reminder for Day 7: "Personal call to [First Name]"
  • This gives them a chance to respond to the emails first
  • If they haven't replied by then, the human touch matters more
  • Make it personal—reference something from their form submission

The best follow-up is still human connection. Automation gets them attention; you close the deal.

Bonus: SMS Follow-Up Sequence

Email is great, but text messages get opened 98% of the time. Here's a 5-message SMS sequence for leads:

  1. Day 0 (Immediate): "Hi [Name]—thanks for reaching out! I got your inquiry and will be in touch tomorrow. [Link to calendar]"
  2. Day 1: "Quick follow-up: Got any questions about [Service]?"
  3. Day 3: "Still interested? Let's schedule a time that works for you: [Link]"
  4. Day 5: "Last check-in—we're moving forward with other clients, but happy to help if timing works for you."
  5. Day 7: "Just wanted to say—door's always open if your needs change. Feel free to reach out anytime."

Use Podium or Twilio for SMS automation. Most cost $20-50/month for basic SMS sequences.

Frequently Asked Questions

What if someone replies to an email? Does the automation stop? +

Yes. Most tools automatically pause the automation when someone replies. This is good—you don't want to send "Email 3 - Last Chance" if they already said yes.

How do I know if the follow-up is working? +

Check your open rates (how many people opened each email) and reply rates. HubSpot and Mailchimp show this in reports. If Email 1 gets 40%+ opens and Email 3 gets 10%+, you're doing well.

Can I use this for different types of customers? +

Absolutely. Create multiple workflows for different scenarios: one for service inquiries, one for product orders, one for demo requests. Each can have its own email sequence.

What if I have leads from before I set this up? +

Import them into HubSpot or Mailchimp (usually a CSV upload). Then manually trigger the automation for past leads, or send a single "re-engagement" email. Don't spam them with all 3 emails at once.
