Do unsubscribed contacts count toward email marketing plan limits?

It depends entirely on the platform, and it is rarely stated on the pricing page. Some count only subscribed contacts; others count every stored record including unsubscribed, bounced, and archived addresses. The difference is commonly 15–25% of a mature list, so it is worth finding the definition of a billable contact in the billing documentation before you compare prices.

Should I delete unsubscribed contacts to save money?

No. The record is what prevents that address being mailed again after a future import, and deleting it removes the only durable evidence that someone opted out. If your platform charges for suppressed addresses, the right response is to change platform rather than to delete consent history — mailing someone who unsubscribed produces a spam complaint, which costs far more than the storage.

How long do I have to keep unsubscribe records?

Indefinitely, in practice. CAN-SPAM requires honouring an opt-out for at least ten years, and GDPR and CASL both expect you to be able to demonstrate the current state of consent. Since the only reliable way to honour an opt-out forever is to keep the record forever, permanent retention is the only workable answer.

What is the difference between unsubscribed and suppressed?

Unsubscribed means the person asked to stop receiving marketing from you. Suppressed is the broader category of addresses excluded from all sending, which includes unsubscribes plus hard bounces and spam complaints. Suppression should apply account-wide rather than per list, because someone who unsubscribed withdrew consent from you, not from one audience.

Why unsubscribed contacts should not count toward your plan

Updated 3 September 2026 · 5 min read · SendKernel

Some email platforms count unsubscribed, bounced, and archived addresses toward your contact limit. Those addresses cannot legally be mailed, and you need to keep them precisely so that nobody mails them again — so you are paying rent on records you are obliged to hold and forbidden to use. On a list a few years old this is commonly 15–25% of the meter, and worse than the cost is the incentive it creates: the cheapest way to get under the limit is to delete the evidence of who opted out.

The short version

A suppressed address is a safety record, not a marketing asset. Charging for it prices the two the same.
Deleting suppression records to save money is how people get mailed after unsubscribing, which produces complaints.
Check the billing documentation rather than the pricing page — the definition of a billable contact is rarely on the page with the prices.
The billing display and the import gate must count the same way, or the product is making a claim its enforcement does not match.

What a suppressed address actually is

When someone unsubscribes, hard bounces, or reports your mail as spam, the correct response is to keep the address forever and never send to it again. The record is not a contact in any commercial sense — it is a permanent instruction not to contact. Keeping it is what stops the same address being mailed again when a colleague re-imports an old CSV eighteen months later.

So the record has real operational value, and none of that value is marketing value. A fair contact meter counts subscribed people who can actually receive a campaign, and stores suppressed addresses at no charge, permanently.

The incentive problem

This is the part that matters more than the money. If unsubscribed addresses count toward a limit, then the cheapest way for a customer approaching that limit to stay on their current plan is to delete them. That is a rational response to the pricing, and it is precisely the behaviour that produces spam complaints — because the deleted addresses come straight back on the next import, and the person who unsubscribed in March receives a campaign in June.

A pricing model should not make the unsafe action the economical one. Charging for suppression records does exactly that, and the resulting complaints damage the sender's reputation, the platform's shared reputation, and the recipient's experience all at once.

What it costs on a real list

Unsubscribe rates run around 0.2–0.5% per campaign for a healthy list, and hard bounces accumulate on top of that. Over a few years of regular sending, the suppressed share of a list commonly reaches 15–25%.

List age	Typical suppressed share	On a 25,000 contact plan
Under a year	5–10%	1,250–2,500 addresses
One to three years	15–25%	3,750–6,250 addresses
Over three years	25–40%	6,250–10,000 addresses

Where suppressed contacts are billable, a mature list can be paying for a quarter of a plan tier in addresses it is not permitted to email — and that share is frequently what pushes an account into the next tier up.

How to check what your platform counts

1Find the definition of a billable contact
It is in the billing documentation or the plan comparison footnotes, rarely on the pricing page. The words to look for are 'subscribed', 'active', 'archived', and 'stored'. 'Stored contacts' generally means everything.
2Compare the number on your billing page to your subscribed count
If they differ, the difference is what you are paying for and cannot use. This takes about a minute and is the most direct answer available.
3Check whether archiving a contact removes it from the count
On some platforms archiving is presented as the fix, but archived contacts still count — which makes it a filing feature rather than a billing one.
4Ask what happens at the limit
Whether hitting the contact limit blocks imports, blocks sending, or triggers an automatic upgrade. All three exist, and the third is the one that surprises people.

The implementation detail that matters

Counting subscribed contacts only is easy to state and easy to get subtly wrong, because the count appears in more than one place. If the billing display counts subscribed contacts but the import gate counts every stored row, then a customer sees 4,000 of 5,000 used and is refused an import of 500 — and no support answer makes that feel fair.

Both paths have to count the same way, and suppression has to be applied before sending rather than at import time, so that an address suppressed after import is still excluded. Where those paths disagree, the product ends up making a promise its enforcement does not keep, which is worse than not making the promise.

Our own position, so it is on the record: the contact meter counts subscribed contacts only, in both the billing display and the import gate. Suppressed addresses are stored free, permanently, and cannot be removed from the dashboard — including by us. The plan limit is 5,000 contacts on Marketing Starter, and unsubscribing someone gives that slot back.
