Mailchimp’s advertised prices are not what most people end up paying, and the reasons are structural rather than sneaky. There are four: the price is tied to contacts stored, the headline figure is a 12-month promotional rate, your send allowance is a multiple of your contact count, and exceeding either limit is billed automatically.
This page explains how the pricing actually works, what each tier gates, and the six things that catch people out. All verified from Mailchimp’s own pricing page in September 2026.
The billing model in one paragraph
You pay for contacts stored, not emails sent. Your monthly send allowance is a multiple of that contact count: 10× on Essentials, 12× on Standard, 15× on Premium. So 10,000 contacts on Standard gives 120,000 sends a month.
Contacts are billed in tiers, and the ladder is long — 0–500, 501–1,500, 1,501–2,500, 2,501–5,000, 5,001–10,000, then bands up to 1,000,000+. Cross a boundary by one address and you move up a tier.
The four plans, and what each gates
Free — 250 contacts
Hard capped at 250 contacts and 500 emails a month or 250 a day. One seat, one audience, limited templates.
What is missing matters more: no marketing automation flows, no email scheduling, no generative AI, and you cannot remove Mailchimp branding. Email support runs for the first 30 days only, then stops.
Overage behaviour differs here too — on Free, exceeding a limit pauses sending. On paid plans it bills you.
Essentials — from $13/month
10× contacts in sends, 3 seats, 3 audiences, 2 roles. Adds scheduling, popup forms and removal of Mailchimp branding.
The automation limit is the thing to notice: up to 4 flow steps. Not four automations — four steps. A welcome series with a wait, a condition and two emails has already used them. Essentials will not carry real lifecycle email.
Also absent: generative AI, branded templates, custom reports, dynamic content. Custom-coded templates can be created but not sent without upgrading.
Standard — from $20/month
12× contacts in sends, 5 seats, 5 audiences, 4 roles. Automation rises to up to 200 flows, and generative AI, branded templates, custom reports and dynamic content all arrive here. One personalised onboarding session included.
This is the plan most businesses actually need. The jump from Essentials is where the automation ceiling lifts from four steps to two hundred flows.
Premium — from $350/month
15× contacts in sends, unlimited seats and audiences, 5 roles, phone and priority support, four onboarding sessions and a dedicated specialist.
Premium is also the only plan with Premium Migration Services — and even then only for new Premium accounts in select countries who contact Sales within the first 30 days.
Six things that catch people out
1. The headline price is a 12-month introductory rate
The $13, $20 and $350 figures are marked “/mo for 12 months”, with “then, starts at” pricing after. The 15% saving is conditional too — it applies to accounts with 10,000+ contacts. Budget for the post-promotional rate.
2. Overages are billed automatically
From Mailchimp’s own FAQ: if you hit your contact or sending limit, “Mailchimp will automatically bill you for your overages.” Campaigns keep running, the account is not paused — you simply get a larger invoice. There is no cap you set in advance. This is the most common source of surprise bills.
3. Mailchimp can move you up a contact tier itself
Also from their FAQ: during the free trial, if your audience grows to where another tier would be “more cost effective”, Mailchimp may upgrade your contact tier so billing starts there. Defensible logic, but your tier is not entirely under your control.
4. Inactive contacts cost real money
Because billing follows stored contacts, list hygiene is a direct cost lever in a way it never is on send-based pricing. Archiving is not tidiness here — it is money. See email list cleaning.
5. SMS credits expire monthly and do not roll over
SMS is an add-on bought in credit blocks that re-purchase automatically each billing date, and unused credits expire each month. Buy for your peak month and you discard the difference every other month.
6. Transactional email is a separate product
Receipts, password resets and order confirmations are not part of a marketing plan — Mailchimp sells transactional separately. For a store or SaaS that is a second subscription and a second sending reputation. See transactional vs marketing email.
What Mailchimp genuinely gives you for the money
Writing only the caveats would be dishonest. The real advantages:
- 300+ integrations — by some distance the largest directory in the category, and a genuine reason to pay a premium if your stack depends on it
- The most familiar editor in email marketing, which matters when handing the tool to someone non-technical
- Real onboarding — a human session on Standard, four plus a dedicated specialist on Premium
- Generative AI at no additional cost on Standard and Premium
- A 15% nonprofit discount, and pay-as-you-go credits for infrequent senders
Where the money goes, compared
For scale at roughly 10,000 contacts, from our tested comparison (verified June 2026 — check vendor pages for current figures):
- Bluey Email $14 — per send
- Brevo ~$17 — per send
- MailerLite $89 — per subscriber
- Omnisend $132 — per contact
- Mailchimp $135 — per contact
- Klaviyo $175 — per profile
- ActiveCampaign $189 — per contact
The gap is widest when your list is large relative to how often you mail it, and narrows sharply if you send daily. A high-frequency sender to a small list can find Mailchimp reasonable value. See Brevo pricing explained for the send-based comparison.
Is Mailchimp worth it?
Yes, if your stack depends on its integration directory, you need a tool a non-specialist will use confidently, or onboarding support genuinely matters.
Probably not, if your list grows faster than your send volume, you store large numbers of contacts you rarely email, or you need transactional on the same bill.
If price is what brought you here, the useful next step is Mailchimp alternatives or Bluey Email vs Mailchimp.
Frequently asked questions
Does Mailchimp charge per contact or per email?
Per contact stored. Your send allowance is a multiple of contacts — 10× Essentials, 12× Standard, 15× Premium.
Is the Mailchimp free plan really free?
Yes, capped at 250 contacts and 500 emails a month. No automation flows, no scheduling, and emails carry Mailchimp branding. Exceeding a limit pauses sending rather than billing you.
What happens if I exceed my Mailchimp limit?
On a paid plan you are billed automatically for the overage and campaigns continue. On free, sending pauses.
Why is my Mailchimp bill higher than advertised?
Usually one of three things: the advertised rate was a 12-month introductory price, you crossed into a higher contact tier, or you were auto-billed for an overage.
Which Mailchimp plan do I need for automation?
Standard, realistically. Essentials caps you at four flow steps, which one welcome sequence can exhaust.
Does Mailchimp include transactional email?
No — it is a separate product with separate pricing.
Does Mailchimp offer migration help?
Premium Migration Services exist, but only for new Premium accounts in select countries contacting Sales within 30 days. Lower tiers get documentation.
If per-contact billing is the problem
Bluey Email bills on emails sent rather than contacts stored, so dormant addresses cost nothing to keep, and transactional sending is included on every plan. For senders above 100,000 emails a month, migration is done hands-on by our team — lists, templates and automations — rather than handed over as a help article. Below that volume we guide you through it.
