by Alkan Balkaya · Last updated: 2026-09-18Yes, several contact-based platforms keep charging you for people who unsubscribed. Whether they do comes down to three counting rules: how unsubscribed contacts are treated, whether the same person on several lists is billed more than once, and how inactive contacts count. Those rules move your bill more than the headline price.
Contact-based pricing looks simple on a plan page. Pick a tier, pay for a range of contacts. The complication is in the definition of “contact.” Two platforms can advertise the same 5,000 contact tier and still hand you very different invoices, because one counts every record you ever imported and the other counts only the people you can actually email.
This guide explains the three rules in plain language, walks platform by platform using only what each vendor states, then shows you how to audit your own bill and run the math before you switch.

Key Takeaways
The three rules are: how unsubscribed contacts are counted, whether one person on multiple lists is billed more than once, and how inactive or bounced contacts count. Every contact-based platform answers these three questions somewhere in its terms, and those answers, not the advertised tier, decide what you pay.
Hold these three rules in mind as you read a plan page. The question is never just “how much per 5,000 contacts.” It is “which of my contacts count toward that 5,000.” That single distinction is the heart of contact based pricing for email marketing.

It varies, and the honest answer for several platforms is “check their current plan page.” Below is what each vendor states about the three rules. Where a rule is not clearly stated, treat it as unknown and confirm it in writing before you commit. Prices below are shown at the 5,000 contact tier (as of 2026-09-07).
Yes. Mailchimp charges for all contacts, including unsubscribed ones, until you archive or delete them from your audience. At the 5,000 contact tier, Essentials runs $75 per month and Standard $100 per month. If unsubscribes are sitting in your audience, they are inside that tier count, so cleaning them up is the only way to stop paying for them.
Constant Contact’s own community answers state that only active contacts are billed and unsubscribed contacts are not counted toward your plan limit. Its billable total is based on active contacts. At the 5,000 tier, Lite is $80 per month and Standard $110 per month. There is no free plan, only a short trial, so the counting rule matters from your first paid cycle.
These three do not spell out the unsubscribe and duplicate rules in the pricing facts we publish, so the honest guidance is to check each plan page before you rely on it. For reference at 5,000 contacts, Klaviyo’s Email plan is $100 per month and ActiveCampaign’s Starter plan is $99 per month. MailerLite’s tier for that range is not stated in our data, so confirm it on their plan page. When you check, ask specifically how suppressed or unsubscribed profiles count and whether a person on several segments is billed once.
Mailsoftly counts each contact once per account, no matter how many lists they belong to, so there is no double charging when a person sits on several lists. Unsubscribed contacts stay in your account and count toward your plan limit only until you delete them. When you delete an unsubscribed contact, the opt-out is preserved on a suppression list, so that person can never be emailed again or re-imported by mistake. You get a clean count and a permanent compliance record at the same time. You can see how Mailsoftly’s contact-based pricing works across every tier.
| Platform | Price at 5,000 | Unsubscribe rule |
|---|---|---|
| Mailchimp | $75 Essentials / $100 Standard | Charges for all contacts incl. unsubscribed |
| Constant Contact | $80 Lite / $110 Standard | Unsubscribed not counted, per its community answers |
| Klaviyo | $100 Email | Check plan page |
| ActiveCampaign | $99 Starter | Check plan page |
| MailerLite | Check plan page | Check plan page |
| Mailsoftly | $39 Basic (annual) | Counts once per account; unsubscribed count only until deleted |
Run a four step audit before you renew or switch. Export your full contact file, remove duplicates, count how many contacts are unsubscribed or bounced, then compare that clean number against the tiers you are being charged for. Most growing businesses discover they are paying a tier or two higher than their real audience needs.
The gap between your raw file and your clean count is your negotiating leverage. If a platform bills every raw record, that gap is money leaving every month. If a platform bills only active, deduplicated contacts, the gap simply disappears from your invoice.
Take a realistic list: 5,000 total contacts with 12 percent unsubscribed. That is 600 opt-outs and 4,400 people you can still email. The counting rule decides whether those 600 keep costing you. Prices below come straight from the reference figures (as of 2026-09-07).
On a platform that bills all contacts (Mailchimp): those 600 opt-outs stay inside the 5,000 tier until you archive them. You pay $75 per month on Essentials or $100 per month on Standard for an audience that is really 4,400 people.
On Constant Contact: unsubscribed contacts are not counted, so the 600 drop out of your billable total automatically. Lite is $80 and Standard $110 at this tier.
On Mailsoftly: the 600 count only until you delete them. Delete them and the opt-out stays on your suppression list forever, so they can never be re-imported or emailed. Your clean 4,400 fits the Basic plan at $39 per month annual, and there is no duplicate surcharge for people on more than one list.
The lesson is not that one sticker price is always lowest. It is that the counting rule can quietly add a tier’s worth of cost, or remove it, on the exact same list. Two platforms at the “5,000” tier can bill you as if you had very different audiences.
Ask five direct questions and get the answers in writing. Vague reassurance on a sales call is not a contract. These questions map straight onto the three counting rules plus the two things that trip people up after migration.
Fair email marketing pricing survives all five questions without a caveat. If a vendor cannot give you a clean answer on how unsubscribed and duplicate contacts count, assume the answer works against your wallet and price the plan accordingly.

Yes. Mailchimp charges for all contacts, including unsubscribed ones, until you archive or delete them from your audience. To stop paying for opt-outs, you have to actively clean them out of your audience, because they otherwise stay inside your contact tier.
No. Constant Contact’s pricing FAQ states that unsubscribed contacts are not counted toward your plan limit; billing is based on active contacts. Always confirm the current wording on their plan page, since vendors update these policies over time.
Only until you delete them. Unsubscribed contacts stay in your account and count toward your plan limit until you remove them. When you delete one, the opt-out is preserved on a suppression list, so they can never be emailed again or re-imported by mistake. Each contact is also counted once per account no matter how many lists they belong to.
Double charging is when the same email address counts as multiple billable contacts because it appears on more than one list or segment. One human on three lists becomes three billable records. Mailsoftly avoids this by counting each contact once per account, regardless of list membership.
Export your list, dedupe by email, and remove unsubscribed and bounced records so your billable count reflects only people you can actually email. Choose a platform that counts each contact once and preserves opt-outs on a suppression list when you delete them, so cleaning your list never risks your compliance record.
