I assess marketing software through 10+ years of agency work, current product research, buyer needs, competing tools and total cost.
How this review was prepared
This is a research-based review. I checked Campaign Monitor's current product pages, pricing, documentation and terms, then assessed what those published limits mean for a marketing team or small agency. I have not presented vendor claims as personal testing.

The Verdict
Is Campaign Monitor right for you?
Campaign Monitor, part of Marigold, is an email marketing platform with three self-serve plans (Lite, Essentials, Premier) and a custom Enterprise plan. Every plan includes unlimited users, and price is set by contact-count bands.
Seen in euros from Finland, monthly billing is €12 (Lite), €29 (Essentials) and €158 (Premier) at up to 500 contacts, rising to €109, €168 and €277 at 5,001 to 10,000 contacts, with 10% off billed annually. A 30-day free trial covers 500 contacts and 500 emails.
It fits a team or agency that values design tools, AI helpers and unlimited seats. It fits poorly when you want a free plan, a refund or transparent USD pricing.
Who It's For
Who Campaign Monitor is for (and who it isn't)
✓ Best for
- +Agencies managing email for several clients. The pricing page lists agency features: tiered account setup, client insights, shared dashboards, private labeling, markup options, template and automation sharing, unique API keys per sub-account and local-currency charging.
- +Teams that need unlimited users and roles. Multiple users, user roles and two-factor authentication are listed as unlimited on every plan, so a growing team does not pay per seat.
- +Marketers who want AI helpers built into the email workflow. AI Writer, AI Email Booster, AI Segment Mapper and Marketing Studio (on-brand emails, images, translations and social posts) are listed, with unlimited AI email features from Essentials.
× Consider something else if
- −You need a free plan or a low entry price for a small list. There is no permanent free plan, only a 30-day trial limited to 500 contacts and 500 emails.Try MailerLite →
- −You want CRM, lead scoring and sales automation. Campaign Monitor is an email and journeys tool. Teams that need sales pipeline features should use a fuller automation platform.Try ActiveCampaign →
- −You want email, SMS and transactional sending under one bill. Campaign Monitor lists SMS and transactional email, but a platform that prices those channels together can be simpler to budget.Try Brevo →
What You Can Do
What can Campaign Monitor do?
Send a designed campaign with reusable templates
Build in the drag-and-drop editor, use custom coded or branded templates, run design and spam testing, and use inbox preview (Essentials and up) before sending.
Automate journeys and drip campaigns
Lite includes drip campaigns, pre-built journeys and automated emails limited to your send volume. Essentials and Premier make automated emails unlimited.
Send transactional email from the same account
The pricing page lists transactional email among the advanced email features, and the API includes transactional endpoints for receipts and confirmations.
Run client accounts as an agency
Agency accounts get sub-accounts, shared dashboards, private labeling and the option to bill clients in local currency, with unique API keys by sub-account.
AI, API & MCP
Does Campaign Monitor Have an MCP Server, API or AI Features?
Campaign Monitor has AI tools inside the product and a mature API. There is no official MCP server.
AI agent workflow
A safe agent workflow
Use the AI tools in the editor for drafts, and let an outside agent read campaign reports through the API.
Approval boundary: Keep sends, list changes and any client sub-account writes behind a human click.
MCP
noneNo official MCP server
Only a small community project exists. I would not build a client workflow on it.
API

How much does Campaign Monitor cost?
Campaign Monitor starts at €12/month (Lite, up to 500 contacts, monthly billing as seen in EUR), with 10% off annual billing and a 30-day free trial.
| Plan | Monthly billing, EUR as seen from Finland |
|---|---|
| Lite, up to 500 contacts | €12/mo |
| Essentials, up to 500 contactsPopular | €29/mo |
| Premier, up to 500 contacts | €158/mo |
| Enterprise | Custom |
Campaign Monitor prices by contact-count band and plan. The pricing page shows euros to visitors in Finland, and its FAQ says it can support USD, CAD, GBP, AUD and NZD by arrangement. The figures below are the euro prices I read, and they may differ from what you see in your region.
Price your contact band, not the entry price
Monthly euro prices read Lite / Essentials / Premier: €12 / €29 / €158 (up to 500 contacts), €44 / €69 / €168 (501 to 2,500), €70 / €109 / €188 (2,501 to 5,000), €109 / €168 / €277 (5,001 to 10,000), €143 / €247 / €406 (10,001 to 15,000), €223 / €397 / €506 (15,001 to 25,000) and €367 / €596 / €993 (25,001 to 50,000). Annual billing takes 10% off.
Lite caps sends and automation volume
Lite sends 5 times your subscriber count in emails a month (2,500 at 500 contacts) and limits automated emails to that volume. Essentials and Premier send unlimited emails.
Features step up at Essentials and Premier
Essentials adds unlimited sends, priority support, inbox preview and unlimited AI email features. Premier adds phone support, send time optimization, advanced link tracking, email section locking, template management and a website builder. A standalone website builder costs €9/month.
Payments are non-refundable
Campaign Monitor's policies say fees paid are non-refundable. Annual plans carry the same rule, so use the 30-day trial to test first.
Alternatives
When I'd choose something else
Three different buying priorities, and what I'd pick instead for each one.
If you want a free plan and a lower entry price
MailerLite
MailerLite offers a free plan and simple tiers for small senders and creators.
Trade-off: It lacks Campaign Monitor's agency account structure and design collaboration features.
Explore MailerLite for this use case →If you want CRM and deeper automation
ActiveCampaign
ActiveCampaign combines email automation with a CRM and sales automation for more complex funnels.
Trade-off: It has more to configure and a steeper learning curve than Campaign Monitor's email-first setup.
Explore ActiveCampaign for this use case →If you want email, SMS and transactional in one platform
Brevo
Brevo bundles marketing email, transactional email and other channels in one platform.
Trade-off: Agency client management is less central than in Campaign Monitor.

Downsides
Limitations to consider before subscribing
No free plan and no refunds
The only free option is a 30-day trial with 500 contacts and 500 emails. Fees paid are non-refundable, including on annual plans.
Pricing is region-specific and USD needs a conversation
The pricing page shows euros from Finland and says other currencies are set up with the team. I could not read US dollar prices, so USD figures elsewhere on TMB need a human re-check.
Contact bands jump quickly
Essentials goes from €168/month at 10,000 contacts to €397 at 25,000 and €596 at 50,000 on monthly billing. Above 50,000 contacts the page shows the same band, which I read as a sales conversation.
Lite is limited on volume and automation
Lite sends 5 times your contact count and caps automated emails at that volume, and it lacks unlimited AI email features.
No official MCP server and AI gaps for agencies
Select AI features may not be available to agency accounts, and there is no MCP server from the vendor.
My Recommendation
Should You Choose Campaign Monitor?
Shortlist Campaign Monitor if you are an agency or design-led team that wants unlimited users, AI drafting and a mature API, and you can price Essentials at your contact band.
Choose MailerLite for a free plan, ActiveCampaign for CRM and deeper automation, or Brevo for email plus SMS and transactional sending.
What to check during the trial
- –Confirm the price in your own currency at your contact band and on both billing modes.
- –Use the 30-day trial to test an automation and a transactional email.
- –Check which AI tools your account type includes, especially on an agency account.
- –Check if you need unlimited sends (Essentials) or can live with 5 times your contacts (Lite).
