You've worked hard to build your customer list. You've delivered great service, sent regular emails, and built genuine relationships. But here's the uncomfortable truth: a significant portion of your list has gone silent.
They haven't opened an email in months. They haven't made a purchase in over a year. They're still on your list, but they've mentally moved on.
Here's why this matters: acquiring a new customer costs five to seven times more than re-engaging an existing one. Every inactive customer represents a relationship you've already built, trust you've already earned, and a buying decision they've already made once. Ignoring them isn't just a missed opportunity—it's leaving money on the table.
The good news? A simple, three-email sequence can bring many of them back. This isn't about aggressive selling or desperate discounting. It's about reminding people why they valued you in the first place, offering a clear reason to return, and—crucially—giving them permission to leave if they're truly done.
This guide shows you exactly how to create and deploy that sequence in under an hour.

Quick Start (5 Minutes)
The Five Essential Steps
1. Define "Inactive" for Your Business
Choose a clear timeframe based on your typical buying cycle:
- •Product businesses: 9-15 months since last purchase
- •Service businesses: 12-18 months since last booking
- •B2B/consulting: 6-12 months since last contact
2. Create Your Segment
In your email platform, create a new segment using filters like:
- •"Last purchase date is more than 12 months ago"
- •"Has not opened any email in the last 6 months"
3. Draft Your Three Emails
- •Email 1 (The Check-In): "We've noticed you haven't been around lately. Here's what you've missed..."
- •Email 2 (The Value Reminder): "Here's why customers like you come back to us..." + special offer
- •Email 3 (The Final Goodbye): "We'll stop emailing unless you want to stay..." + last chance offer
4. Set Up the Automation
Create an automated sequence that sends:
- •Email 1 immediately
- •Email 2 after 7 days
- •Email 3 after another 7 days
5. Launch and Monitor
Activate the sequence and check your open rates after 48 hours. You should see higher-than-average engagement if your segment is accurate.

Complete Step-by-Step Guide: Deploying the Win-Back Sequence
This section walks you through each step in detail, including the psychology behind each email and exactly what to write.
Step 1: Define Your Inactivity Window
The right timeframe depends entirely on your business model and typical customer behaviour.
For product-based businesses: Consider your product's natural replacement cycle. If you sell coffee beans, 3 months might be inactive. If you sell furniture, 2 years might be normal.
For service businesses: Think about your typical rebooking pattern. Hairdressers might consider 4 months inactive, while accountants might use 18 months.
For B2B or consulting: Factor in project cycles and decision-making timelines. Six months without contact might warrant a check-in.
The practical approach: Start with a conservative definition. It's better to contact someone slightly too early than to let them forget you entirely. You can always refine based on results.
Action: Write down your definition: "A customer is inactive if they haven't [purchased/booked/contacted us] in [X] months."
Step 2: Segment the Target List
Now you'll create a filtered list containing only your inactive customers.
In most email platforms, you'll find segmentation under "Audiences," "Lists," or "Segments." You're looking for the ability to filter based on:
- •Last purchase date
- •Last email open date
- •Last click date
- •Tags or custom fields
Example filter logic:
- •"Last purchase date" is more than "365 days ago"
- •AND "Has opened an email" is "false" in the last "180 days"
This gives you people who haven't bought in a year AND haven't engaged with your emails in six months—a strong indicator of inactivity.
Example of defining "inactive" (e.g., Last Purchase Date > 365 days ago) within a typical email platform.
Action: Create a new segment called "Inactive Customers - [Date]" and apply your filters. Note the total number—this is your opportunity pool.
For detailed guidance on segmentation techniques, see Email Segmentation for Micro Businesses.
Step 3: Draft Email 1 – The Soft Check-In
This first email is about reconnection, not selling. The goal is to remind them you exist and that you've noticed their absence.
Subject line examples:
- •"We've missed you, [Name]"
- •"It's been a while..."
- •"Are we still a good fit?"
Email structure:
- •Opening: Acknowledge the gap without guilt-tripping
- •Middle: Briefly remind them of what you offer and what's new
- •Close: Soft invitation to re-engage (visit, browse, reply)
Example copy:
> Hi [Name],
>
> I noticed it's been about [timeframe] since we last connected, and I wanted to reach out personally.
>
> A lot has changed since then—we've [mention 1-2 improvements, new products, or achievements]. But more importantly, I wanted to make sure we're still relevant to you.
>
> If you're still interested in [core benefit you provide], I'd love to have you back. If not, no hard feelings—I completely understand priorities change.
>
> Either way, I'd appreciate knowing where we stand.
>
> [Your name]
Tone: Personal, humble, curious. Avoid desperation or hard selling.
For crafting subject lines that actually get opened, see Email Subject Lines That Get Opened.
Action: Draft your first email using the structure above. Keep it under 150 words.
Step 4: Draft Email 2 – The Direct Offer
If they opened Email 1 but didn't act, Email 2 provides a clear, time-limited incentive to return.
Subject line examples:
- •"Here's 20% off to welcome you back"
- •"A special offer just for you"
- •"We'd love to earn your business again"
Email structure:
- •Opening: Reference that they're still on your mind
- •Middle: Present a specific, valuable offer with a deadline
- •Close: Clear call-to-action with easy next step
Example copy:
> Hi [Name],
>
> Since you opened my last email, I'm guessing there's still some interest in what we do—and that makes me genuinely happy.
>
> To make coming back as easy as possible, I'd like to offer you [specific offer: 20% off, free shipping, complimentary consultation, etc.]. This offer is valid until [specific date—7 days from send].
>
> [Clear CTA button: "Claim Your Offer"]
>
> No strings attached. Just a genuine thank you for considering us again.
>
> [Your name]
The offer: It doesn't have to be a massive discount. Free shipping, a bonus item, priority booking, or a free consultation all work. The key is making it feel special and time-bound.
If you're unsure about the cleanliness of your existing customer data—which is essential for accurate segmentation—NetNav can audit your data sources and check for integration issues that might prevent accurate inactive customer tracking.
Action: Draft your second email with a specific offer and deadline. Create the landing page or booking link they'll click through to.
Step 5: Draft Email 3 – The Goodbye/Re-Permission
This is the most important email in the sequence. It serves two purposes: giving truly disinterested people an easy exit, and creating urgency for those on the fence.
Subject line examples:
- •"Last email from us (unless you want to stay)"
- •"Should we say goodbye?"
- •"This is it—stay or go?"
Email structure:
- •Opening: Acknowledge this is the final contact
- •Middle: Offer one last incentive OR simply ask if they want to stay
- •Close: Two clear options—stay or unsubscribe
Example copy:
> Hi [Name],
>
> This is my last email to you—I promise.
>
> I've reached out twice now, and I haven't heard back. That's completely fine. I respect your time and your inbox.
>
> But before I remove you from our list, I wanted to give you one final choice:
>
> Option 1: [Click here to stay subscribed] – You'll keep hearing from us with [what they'll get: tips, offers, updates].
>
> Option 2: Do nothing, and I'll remove you from our mailing list in 7 days.
>
> Either way, thank you for being a customer. It genuinely meant something to us.
>
> [Your name]
Why this works: It respects their autonomy, cleans your list of dead weight, and creates a "last chance" psychological trigger for those who were simply distracted.

Action: Draft your third email with clear stay/go options. Set up the "stay subscribed" link to tag them as re-engaged.
Step 6: Build the Automated Sequence
Now you'll set up the automation that sends these emails automatically with the right timing.
In your email platform, create a new automation or workflow. The structure should be:
- Trigger: Contact enters the "Inactive Customers" segment
- Action: Send Email 1 immediately
- Wait: 7 days
- Action: Send Email 2
- Wait: 7 days
- Action: Send Email 3
- Action: If no engagement, remove from main list or tag as "Unengaged"
Timing considerations:
- •7 days between emails gives people time to see and act without feeling spammed
- •Send emails on Tuesday-Thursday for best open rates
- •Avoid Mondays (inbox overload) and Fridays (weekend mode)
For more on setting up email automation, see Set Up Email Automation for New Enquiries.
Action: Build the automation sequence in your email platform with the correct timing and email content.
Step 7: Test and Launch
Before activating the sequence for your entire inactive list, run a critical pre-flight check.
Test checklist:
- •☐ Add yourself to the segment and verify you receive all three emails
- •☐ Check that all links work correctly
- •☐ Verify personalisation tokens (like [Name]) populate correctly
- •☐ Confirm emails display properly on mobile devices
- •☐ Check that the timing delays are set correctly
- •☐ Verify the unsubscribe link works in Email 3
Soft launch option: If you're nervous, start with a small subset (50-100 contacts) and monitor results for a week before rolling out to the full list.
When you run a re-engagement campaign, you're hoping customers click through to convert. If your landing page has technical issues or poor mobile performance, that effort is wasted. NetNav can run a conversion audit to ensure there are no technical leaks losing those returning leads.
Action: Complete the test checklist, then activate the automation for your inactive segment.
Step 8: Measure Success Metrics
Re-engagement success isn't just about immediate purchases. You're looking for signs of renewed interest.
Key metrics to track:
Open rates: Your inactive segment should show higher-than-average open rates (15-25%+) if your subject lines and timing are right. This proves people remember you.
Click-through rates: Even 2-5% is a win. These are people who haven't engaged in months—any click is progress.
Re-purchases: The ultimate goal, but don't expect massive numbers immediately. Even 1-3% conversion represents significant recovered revenue.
List cleaning: How many people unsubscribed? This is actually positive—you're removing people who were never going to buy anyway, which improves your overall email deliverability.
Re-engagement tags: How many people clicked "stay subscribed" in Email 3? These are warm leads worth nurturing differently going forward.

Action: Set a calendar reminder to review these metrics 14 days after launch. Document what worked for future campaigns.
