How to re-engage inactive email subscribers (and why some may still be reading)

Why "hasn't opened" stopped meaning "isn't reading"

Many email tools estimate opens by loading a tiny tracking image in the message. When the image loads, the tool can record an open.

That system has always been a bit shaky, and it's got much shakier.

Apple's Mail Privacy Protection can download remote content in the background, even if the recipient does not engage. Apple Mail Privacy Protection source A tracking image may load without a person reading the message. Other people block images or use apps that do not load the tracking image, so a read may go uncounted.

Open data can be fuzzy in both directions. Some recorded opens may happen automatically. Some real reads may go uncounted.

That doesn't make your email tool useless. It just means opens alone are a poor way to decide who has stopped caring.

Thornfield Linen finds active customers among its "inactive" list

This is a hypothetical example.

Thornfield Linen is a two-person business making linen tea towels, aprons and napkins, printed by hand with botanical designs. They have about 2,400 people on their email list.

One January, their email tool flagged about 600 subscribers as inactive. No opens in six months. The tool suggested removing them to "improve list health".

Clodagh, who runs the emails, nearly did it. Then she had a thought. Before deleting anyone, she'd check those 600 against her actual orders.

Here's what she found:

Thornfield's 600 "inactive" subscribers


- 74 had bought something in the last six months.
- 31 of those had clicked a link in an email before buying.
- 19 had replied to an email at some point, asking a question.
- Several had bought the Christmas apron set within a day of the email announcing it.

So more than one in ten of her "inactive" list were active customers. Some of them were among her best.

If she'd deleted them all, she'd have cut off people who were clearly reading her emails in a way the tool couldn't see.

Find out who is really inactive before you send anything

Here's a simple way to sort your list. You don't need special software. Most email tools let you filter or export subscribers, and your shop platform can export orders.

Step 1: Start with the tool's list of non-openers

Choose a sensible time window. A six-month window can be a useful starting point.

If you email monthly or less, try nine months or a year instead. Someone who skips three monthly emails isn't necessarily gone.

Step 2: Check the click records

A recorded click is a stronger signal than an open, but it isn't proof that a person read the email. Treat clickers as a separate group and cross-check orders or replies before deciding what to do.

Step 3: Check recent orders

Compare email addresses with recent orders. A purchase shows buying activity, but it doesn't prove that a person wants ongoing marketing emails.

Keep purchase history separate from consent and subscription status. A gift buyer, for example, may not want your regular messages.

Step 4: Take out anyone who replied

If someone replied to an email, they read it. Search your inbox for replies from those addresses, or just think about the regulars you know.

Step 5: Take out anyone who joined recently

Someone who signed up two months ago hasn't had a fair chance yet. Leave new subscribers alone.

Before building the segment, check the fields you will use. Make sure the export includes subscription status, join date, clicks, replies and recent orders.

Match records by the email address on the subscriber account, and review orders made under another address. If the evidence is unclear, set the record aside instead of guessing.

What's left is your genuinely quiet group. It will usually be smaller than the number your tool showed you. For Thornfield, it went from 600 down to about 420.

Why some may buy without a recorded open

Before we write the email, it's worth pausing on that group Clodagh found. The people who seem never to open but always seem to buy.

Who are they?

Some read on apps that don't report opens. Others see your subject line, think "Ah, the new aprons are out", and go straight to your website without opening the email.

The subject line did its job. The tool just never knew.

This changes how you think about your emails. Your subject line might be selling more than your open rate suggests. A clear subject like "The new apron prints are here" might be enough on its own for some people.

It's also a reason to be careful with any automatic "remove inactive subscribers" setting. If your tool offers one, check exactly what it uses to decide. If it only looks at opens, it may be removing customers.

Write a re-engagement email that asks one easy question

Now you've got your genuinely quiet group. What do you send them?

Most "win back" emails say something like "We miss you!" with a discount code. A discount may trigger a click or purchase, but that alone won't tell you whether someone wants your regular emails. Ask for a preference instead.

A better approach is to ask one simple question that people can answer with a single click.

Thornfield's re-engagement email


Subject: Do you still want our emails? (one click either way)


Hi,


You joined our list a while ago, and we haven't heard from you in a bit. That's completely fine. People's lives change.


We want to email people who want to hear from us. Which option suits you?


[Button: Yes, keep sending them]
[Button: Fewer emails, please (just new prints and Christmas)]
[Button: No thanks, take me off]


If you don't click anything, we'll take you off the list in a few weeks, so you won't be bothered. You can always join again on our website.

Look at what this does.

The subject line is honest and tells people what's inside. The tone is relaxed, not guilty.

There are three clear choices, including a middle option. The email also explains what happens if they do nothing.

Why the middle option matters so much

That "Fewer emails" button gives people who still want some messages a practical middle choice.

Some quiet subscribers may still want your emails, but your rhythm was more than they wanted. A third option gives them a way to ask for fewer messages instead of choosing only "stay" or "leave".

Clodagh set up a small group in her email tool for "new prints and Christmas only". About a fifth of the people who answered chose it. Those subscribers now get about four emails a year, and they open them.

Most email tools let you set up groups, tags or lists like this. The button just adds people to the right group when they click.

When to send it and how many times

Don't send a re-engagement series of five emails to people who weren't reading your first one. Keep it short.

Before sending, test each choice with a safe test contact. Click "stay", "fewer" and "remove", then confirm each option updates the expected group.

Check that the unsubscribe choice updates your platform's suppression record. A broken button can turn a clear question into a confusing email.

The reminder can be very short:

Subject: Last check: keep getting Thornfield emails?


Hi,


Just a quick last check. If you'd like to keep hearing from us, click below.


If not, no need to do anything. We'll take you off next week.


[Button: Keep me on the list]

What to do with the people who still don't answer

After the reminder, some people will still have done nothing. That's normal. For Thornfield, about two-thirds of the quiet group never clicked anything.

You have a few choices.

Option 1: Remove them

This is the cleanest option. They didn't respond to two clear, friendly emails asking if they wanted to stay. Remove them, as you said you would.

Removing people can feel painful, especially if you remember the day you hit 2,000 subscribers. But a list of people who don't read your emails isn't helping you. It can actually work against you.

Option 2: Move them to a "rarely" group

If you can't bear to remove them, move them into a group that gets only your one or two most important emails. Christmas last-order dates are one example.

This gives them a softer landing. Over the next year, you can see whether any choose to engage again.

Just make sure you've said in your re-engagement email what will happen, so you're doing what you promised.

Before removing anyone, check a small sample of the remaining addresses. Confirm they are still subscribed, the reminder went to the right segment and the choice links worked.

Keep a note of the date and count you removed. Keep suppression records so an unsubscribe is not accidentally added back later.

What not to do

Don't keep sending to someone who has unsubscribed, complained or asked you to stop. Google's sender guidelines say to send only to people who want your messages and periodically confirm they want to stay subscribed. Google email sender guidelines

Google also recommends considering unsubscribes for people who don't open or read. Google email sender guidelines Follow your platform's rules for subscription status and suppression. A re-engagement email is not a way around them.

What a smaller list can and cannot tell you

This is the bit that feels backwards, so let's spell it out.

Removing non-responders may make the share of people with recorded activity look higher because the list is smaller. That does not prove you created more interest or made more sales. Track clicks, replies and orders separately, and compare like with like.

List cleanup does not guarantee better inbox placement. It gives you a clearer view of who responds and helps you stop sending reminders to people who have opted out.

There's also a more practical benefit. Many email tools charge based on the number of subscribers. Paying to email hundreds of people who never read anything is money that could go elsewhere.

Thornfield went from about 2,400 subscribers to just under 2,000. Their next new-print email had more clicks than the one before, from fewer people. Clodagh said it was the first time she'd felt the list was made of people rather than numbers.

How to stop subscribers going quiet in the first place

Re-engagement is the repair job. It's worth thinking about why people drift, so you need to do it less often.

Check the promise on your signup form

People often go quiet because what they got wasn't what they expected. If your form promised "new prints and offers" and they're getting weekly emails about your studio, some will tune out. Make sure the form describes what you actually send.

Give people a "less" option from the start

You don't have to wait for someone to go quiet to offer fewer emails. Some shops put a small line at the bottom of every email: "Too many emails? Switch to new prints only." It catches people before they drift.

Look at who drifts and when

When you run your re-engagement check, notice where quiet subscribers came from. Did some join through a giveaway or a discount pop-up? People who signed up for a one-off reward may go quiet after using it.

That doesn't mean you should stop running offers. It may change how you use them.

Clodagh found that most of her quiet subscribers had joined during a giveaway with another brand. Most of her market signups, on the other hand, were still very engaged. That told her where her best subscribers came from.

What the replies to your re-engagement email will teach you

Most people will click a button or do nothing. But a few will reply, and those replies are worth reading slowly.

When Thornfield sent their email, about thirty people wrote back. Clodagh sorted the replies into rough groups.

• "I changed my email address." Several people still wanted the emails but were reading at a new address. The old one was barely used.
• "I bought a gift once, it's not really for me." Honest, polite leavers. Easy to remove.
• "I love the emails, I just don't open them all." Exactly the quiet readers the tool couldn't see.
• "Too many emails around Christmas." Useful feedback about one busy season.

An address change gives you a simple next step. People may change jobs, leave school or stop using an old account. The person may still want your emails; the old address simply stopped working for them.

Make it easy to update an email address

After reading those replies, Clodagh added one line to the bottom of her re-engagement email:

"Using a different email address these days? Reply with the new one and we'll switch you over."

Several people did. That's a subscriber kept, not lost, and it took one sentence.

Keep a note of what you learn

Write down the reasons people give, even roughly. If several say "too many emails", review your sending rhythm. If someone says "it was a gift", consider whether gift buyers need a different follow-up.

If people say they changed address, include the update line in your next message.

Each round of re-engagement gets easier, because you start to understand why your particular subscribers drift.

How often to check for inactive subscribers

You don't need to do this every month. A check once or twice a year may be enough. Pick a rhythm that fits your normal sending schedule and your shop's busy seasons.

A good time is just before a busy season. If you tidy your list in September, your Christmas emails go to people who still want them. This does not guarantee inbox placement.

Put a reminder in your calendar. It takes an hour or two each time, mostly spent checking orders against the quiet list.

Your re-engagement checklist

• I've picked a sensible time window for my sending rhythm.
• I've removed anyone who clicked, bought, replied or joined recently from the "inactive" group.
• I've noted the people who buy but never seem to open.
• My email asks one clear question with three options: stay, fewer emails, or leave.
• The email says what happens if people don't click.
• I've sent one reminder and no more.
• I've done what I said with people who didn't answer.
• I've checked my signup form promise against what I actually send.
• I've put a reminder in my calendar to do this again in six to twelve months.

Quiet doesn't always mean gone

The big lesson here is to be curious before you're decisive.

Some people labelled "inactive" may still be reading in ways your tool can't see. Some may want fewer emails. And some have moved on, which is fine.

Sort them carefully, ask them kindly, and do what you promised. You'll have a clearer view of who wants your emails and which subscribers need a different choice.
