# What 'Cleaned' Means in Mailchimp, and Why It Is a Billing Answer

> A cleaned Mailchimp contact has hard bounced or repeatedly soft bounced. The part nobody mentions: cleaned contacts stop counting toward your plan price, while unsubscribed ones keep counting.

Seven hundred and twenty people a month ask what "cleaned" means in Mailchimp, across
five different phrasings of the same question. That is more than ask how to use the product, and
more than ask who its competitors are.

They are asking a deliverability question. The answer is a billing one.

**OUR TAKE:** A cleaned contact is an address Mailchimp has decided is dead, and the important part
is not that it has stopped receiving email. It is that it has stopped costing you money. Cleaning
is one of two documented ways a contact leaves your invoice in this product, and it is the one that
happens without you asking. Most people who search for this never find that out.

## What the vendor actually says

The definition is one sentence: "Cleaned contacts have email addresses that have hard bounced or
repeatedly soft bounced, and are considered invalid."[14]

The cause is the next paragraph: "If you send an email to an invalid email address, it'll likely
hard bounce. A hard bounce indicates a permanent reason an email can't be delivered. Hard bounces
may be the result of a typo in an email address, server problems, or an outdated address. In most
cases, Mailchimp will automatically remove addresses from your audience that hard bounce."[14]

Two mechanisms, then. One hard bounce is usually enough. Repeated soft bounces get there eventually.

And the consequence for the contact is absolute. A cleaned address receives nothing further, and it
cannot be mailed again without the person re-subscribing.



> 💡 **undefined:** Archive at the start of a billing cycle, not the end. The bill runs on the peak contact total, so early archiving sets the whole month's ceiling lower.

## The part nobody tells you

Here is the sentence that turns this from a deliverability topic into a billing one: "Archived,
cleaned, and deleted contacts don't count toward your contact total or the price of your marketing
plan."[5]

Cleaned contacts are free. They sit in your audience, visible in your reporting, and they are not
in the number that sets your band.

The other half of that sentence is what makes it useful: "Subscribed, unsubscribed, and
non-subscribed contacts are included in your contact count."[5] So someone who unsubscribed
three years ago is still on your invoice, and someone whose mailbox was deleted is not.

That asymmetry is the whole practical lesson. A dead address costs you nothing. A live person who
asked you to stop costs you the same as a customer.

## Why a decaying list gets cheaper

List decay is normally described as a problem, and in deliverability terms it is. In billing terms
it is a refund you did not apply for.

Every address that hard bounces moves from billable to non-billable automatically. A list that has
not been mailed in a year and then gets a campaign will shed a visible percentage of itself into
cleaned status within hours of that send, and the next invoice reflects a smaller contact total.

This is why the first send to an old list often looks alarming and then helps. The bounce report is
ugly. The billing effect is not.

What it does not do is help your sender reputation, which is the reason not to treat cleaning as a
list-hygiene strategy. The bounces that produce cleaned contacts are the same bounces that mailbox
providers count against you.



> 💡 **undefined:** Once a year, look at what proportion of your audience is unsubscribed. That is the largest billable category nobody watches.

## Cleaned against archived, which people confuse

Both take a contact off your bill. They are otherwise nothing alike.

| | Cleaned | Archived |
|---|---|---|
| Who does it | the platform, automatically | you, deliberately |
| Why | the address hard bounced or repeatedly soft bounced | your choice |
| Counts toward your bill | no | no |
| Can you mail them | no, and not again | no, until you unarchive |
| Reversible | only if they re-subscribe | yes, by unarchiving |
| Data preserved | yes | yes, including in reports |

The archived definition in full: "When you archive an email or SMS contact, they are removed from
the contact table and added to a separate archived contacts table. You won't be able to edit an
archived contact's profile or send them marketing emails or texts. Their data is preserved,
including identifiable information in email or SMS reports. Archived contacts don't count toward
your billing tier."[15]

So cleaning is the platform telling you an address is gone. Archiving is you telling the platform a
person is not worth paying for this month.

## The lever most people never pull

Archiving is the actionable half of this, and it is worth being concrete about what it is worth.

Mailchimp's bands at the bottom of the ladder are narrow: nought to five hundred, then five hundred
and one to fifteen hundred, then to two and a half thousand, then to five thousand[2]. An
account at five thousand one hundred contacts is in the five to ten thousand band. Archiving two
hundred lapsed contacts moves it down a band.

Whether that saves money depends entirely on where you sit relative to a boundary, which is why the
habit is worth most to accounts just above one. The price of eighteen of the twenty published bands
is not available, so we cannot tell you what each step down is worth; we can tell you the steps
exist and that the lever moves you between them.

One timing rule governs all of it: the bill is computed on "the peak contact total during your
billing period"[6]. Archiving on the last day of a cycle does nothing for that cycle. Archiving
on the first day sets the whole month's ceiling lower.



> 💡 **undefined:** After a campaign to an old list, read the bounce report. The cleaned count rising is the platform doing your billing hygiene and warning you about the list's age at the same time.

## What cleaning does not fix

Three things, and they are the reason not to rely on it.

It does not help your reputation. The hard bounces that produce cleaned contacts are recorded by
mailbox providers, and a campaign that generates many of them can affect delivery of the next one
to good addresses.

It does not reach people who have gone quiet. A subscriber who never opens anything but whose
address still accepts mail is never cleaned. They stay billable indefinitely, and only archiving
moves them.

And it does not apply to the largest group on most old lists. Unsubscribed contacts are explicitly
billable[5], and unsubscribing is far more common than a mailbox being deleted.

So cleaning handles the addresses that died. Everything else is your decision.

## Why this question gets asked so often

Seven hundred and twenty searches a month across five phrasings is a lot for a single word in one
product's interface, and the pattern of the phrasings says why.

People search for what cleaned means, what cleaned means in Mailchimp, what cleaned on Mailchimp
means, what Mailchimp cleaned means and what clean means in Mailchimp. Five ways of asking the same
thing is the signature of a term encountered in the wild rather than looked up deliberately. Nobody
plans to learn this word. They see a number and go looking.

For comparison, two hundred and sixty people a month search for a Mailchimp tutorial and four
hundred and eighty for how to use it. So more people arrive at this product's documentation through
a confusing status label than through any deliberate attempt to learn the product.

That is worth a sentence of credit to the vendor. The answer exists, it is clearly written, and it
sits one click from the dashboard. What it does not do is mention the billing consequence in the
same breath, which is why this article exists.



> ⚠ **undefined:** A cleaned address cannot be mailed again unless the person re-subscribes.

## The three categories, priced

Put the vendor's two sentences side by side and the whole economics of an audience falls out.

| Status | Can you mail them | Counts toward your bill | Who decides |
|---|---|---|---|
| Subscribed | yes | yes | them |
| Non-subscribed | no, not marketing | yes | them |
| Unsubscribed | no | yes | them |
| Cleaned | no, permanently | no | the platform |
| Archived | no, until unarchived | no | you |
| Deleted | no | no | you |

Six statuses, three of them billable. Read the right-hand column: the only two statuses you control
are archived and deleted, and both of them stop the charge.

Non-subscribed is the one that surprises people most. It covers contacts who arrived through a
purchase or a form without opting into marketing[5]. You cannot market to them and you pay for
them, which is the least intuitive cell in the table.

## What to do about the unsubscribed

This is the group the cleaned question leads to, and almost nobody follows the thread.

Unsubscribed contacts are billable[5]. On a list that has run for a few years they are often
the largest non-active category, and unlike cleaned contacts nothing removes them automatically.

You have two documented options. Archive them, which preserves their data and their presence in
reports while taking them off the billing tier[15]. Or delete them, which also removes the data.

Archiving is almost always the right answer, because the reporting history stays intact. The one
thing to check first is whether your own compliance position requires you to retain evidence that
someone unsubscribed, in which case archiving keeps it and deleting does not.

Do it at the start of a billing cycle. The peak-total rule makes the timing worth real
money[6].



> ⚠ **undefined:** Cleaning does not help your sender reputation. The same bounces that produce it are counted against you by mailbox providers.

## What the number in your dashboard is telling you

If you arrived here because a cleaned count appeared and you wanted to know whether something broke,
the short answer is that something is true rather than broken.

A cleaned count that rises after a campaign to an old list is the platform discovering which
addresses no longer exist. That is information about the list, and the vendor states the mechanism
plainly: one hard bounce is usually enough, and repeated soft bounces get there eventually[14].

A cleaned count that rises after a campaign to a fresh list is worth investigating, because it
suggests a collection problem rather than an age problem. Typos from a manual import, a form
without validation, or a purchased list all produce the same symptom.

And a cleaned count that never moves on a list you have not mailed in a year means nothing at all.
Cleaning only happens on send. An address cannot bounce until something is sent to it, which is why
the first campaign after a long gap produces the largest jump.

None of that affects what you are charged for those contacts. It affects what you should conclude
about where the contacts came from.

## The reputation cost, which cleaning does not pay

One caution so this does not read as an argument for letting a list rot.

The bounces that create cleaned contacts are the same bounces mailbox providers record against your
sending domain. A campaign that generates a high proportion of them can affect whether the next
campaign reaches the addresses that still work.

So the billing effect and the deliverability effect point in opposite directions. Cleaning reduces
your bill and the event that produces it damages your reputation, and the damage lands on the good
addresses rather than the dead ones.

The practical implication is that a long-dormant list should be warmed rather than blasted: a
segment at a time, oldest and least engaged last, watching the bounce rate between sends. You end up
in the same billing position with less reputational cost.

Mailchimp does not publish guidance tying those two effects together, and the two help articles that
cover them sit apart from each other. The connection is ours rather than the vendor's.



> ⚠ **undefined:** A subscriber who never opens anything but whose address still works is never cleaned. Only archiving removes them from your bill.

## A routine worth adopting

Four steps, all free, all built from documented behaviour.

At the start of a billing cycle, archive contacts who have not opened anything in a defined window.
You keep their data and their presence in reports[15], and the month's peak is set lower from
day one.

Before a large import, check which band you are in and how close the import takes you to the next
boundary. The peak rule means an import you reverse still costs the month[6].

After a campaign to an older list, read the bounce report and expect the cleaned count to rise.
That is the platform doing your billing hygiene, and it is also a warning about the list's age.

And once a year, look at the proportion of your audience that is unsubscribed. That group is the
single largest billable category nobody is paying attention to.

## How this compares with the rest of the category

Mailchimp's contact rule is the most forgiving we have measured, and that is worth placing beside
the alternatives.

ActiveCampaign, the one competitor we have measured in full, publishes the opposite rule: every
contact counts toward the limit regardless of list status. No archiving lever, no exemption for
dead addresses in the billing sense. On a churned list that is a structural difference of a band or
two every month.

Kit changes the basis instead of the exemption, pricing on email subscribers rather than on all
contacts, which excludes much of the same population by definition rather than by action.

MailerLite bills active subscribers and publishes its own timing rule: subscribers you delete keep
counting until your billing date, so deleting on the first with a billing date on the fifth buys
you nothing that cycle.

Four vendors, four different answers to the same question. None of them is on a feature comparison
table anywhere, and it is the single largest determinant of what the same list costs at each one.

So the useful version of the cleaned question is not what the word means. It is which of my
contacts does this vendor charge me for, and the answer differs enough between products to outweigh
the headline prices.



## FAQ

**What does cleaned mean in Mailchimp?**

A cleaned contact has an email address that has hard bounced or repeatedly soft bounced and is treated as invalid. Mailchimp removes most hard-bouncing addresses from your audience automatically, and a cleaned address receives nothing further unless the person re-subscribes.

**Do cleaned contacts count toward my Mailchimp plan?**

No. The vendor states that archived, cleaned and deleted contacts do not count toward your contact total or the price of your marketing plan. Subscribed, unsubscribed and non-subscribed contacts all do.

**What is the difference between cleaned and archived?**

Cleaning is automatic and permanent: the platform decides an address is dead. Archiving is your decision and reversible: the contact's data and reports are preserved, you cannot edit or market to them, and they leave your billing tier until you unarchive them. Both stop counting toward your bill.

**Can I recover a cleaned contact?**

Not by re-adding them. A cleaned address cannot be mailed again unless the person subscribes again themselves, which is the platform's protection against repeatedly sending to an address that has already failed.

## The question behind the question

People search for what cleaned means because a number in their dashboard changed and they want to
know whether something is wrong.

Usually nothing is wrong with the platform. Something is true about the list: part of it no longer
exists. The platform has removed those addresses, stopped charging for them, and left them visible
so the reporting still makes sense.

The genuinely useful follow-up question is the one almost nobody asks. Not what cleaned means, but
which of my contacts are costing me money and doing nothing. The answer is in the same
documentation, two sentences away, and it is the difference between a band boundary and a bill you
did not need to pay.
