Campaign Monitor is the email platform we would recommend to design-led brands that want every campaign to look like it came from an agency, but for most small businesses it costs more than Mailchimp or Brevo while offering less automation. This Campaign Monitor review compares its subscriber-based pricing and documented feature set against both alternatives, and the pattern is clear: the template builder and deliverability pedigree are real strengths, but the price scales steeply with your list and the automation trails the leaders. If polished visual email is your top priority, it earns its price; if you need advanced automations on a budget, look elsewhere first.
For this review, we compared Campaign Monitor's documented plans, feature list, and reviewer-reported weaknesses against Mailchimp and Brevo. We priced out the same list size on all three platforms, weighed where each one is strong, and identified the businesses where each makes sense.
How We Compared These Tools
We compared Campaign Monitor, Mailchimp, and Brevo using publicly documented pricing, vendor feature lists, and consistent patterns in published customer reviews. We did not send campaigns on live accounts. Email pricing depends on subscriber counts and billing terms that change often, so verify current pricing at each vendor before deciding. We weighted four factors: cost at typical small-business list sizes, design capability, automation depth, and deliverability track record.
Campaign Monitor Priced Out: Subscriber Tiers That Climb Fast
Campaign Monitor has three paid plans, Lite, Essentials, and Premier, all priced by subscriber count, with no permanent free plan. At around 500 subscribers, third-party price comparisons document Lite near $11 per month, Essentials near $19, and Premier near $149, with annual billing discounting roughly 10 percent. The climb is the issue: at 25,000 subscribers the same sources document roughly $219 for Lite, $269 for Essentials, and $499 for Premier. Lite also caps the emails you can send each month, while Essentials and Premier send unlimited. Verify current pricing with the vendor's own calculator, because tiers shift. The honest takeaway: the entry price looks small, but the bill grows faster with your list than most rivals.
Design and Deliverability Are the Real Strengths
The reason brands pay for Campaign Monitor is the builder. The drag and drop editor produces email that renders consistently across clients, templates lock so non-designers cannot break brand rules, and the canvas approach lets a central team control layout while local teams swap content. Reviewers consistently report polished results with minimal design skill, and the company's long deliverability history still carries weight in published comparisons. Signup forms, basic segmentation, and a clean API round out the core. For businesses where the newsletter is the brand, such as agencies, publishers, retailers, and nonprofits running donor communications, this focus is genuinely valuable.
The Weaknesses: Automation Gaps and Costly Scaling
Two criticisms dominate published reviews. First, automation: Campaign Monitor handles autoresponders and simple journeys, but its automation builder trails ActiveCampaign, Brevo, and even Mailchimp in depth, and advanced features sit on the expensive Premier tier. Second, price scaling: because billing keys off total subscribers rather than contacts you actively email, growing a list raises your bill even when many subscribers are dormant, and there is no free tier to offset the cost. Some reviewers also note that the lower tiers omit features rivals include by default, such as advanced spam testing and time-zone sending. For automation-first marketing teams, these gaps matter more than the pretty templates.
How Campaign Monitor Stacks Up Against Mailchimp and Brevo
Mailchimp is the all-in-one choice with marketing pages and a broad app ecosystem, Brevo is the value choice with contact-based pricing and strong transactional email, and Campaign Monitor is the design choice. The table below sums up the trade-offs at comparable list sizes.
| Factor | Campaign Monitor | Mailchimp | Brevo |
|---|---|---|---|
| Entry cost, small list | About $11 per month for 500 subscribers on Lite, verify current | Free tier available, paid plans from roughly $13 per month | Free tier available, paid plans from about $9 per month |
| Cost at 25,000 subscribers | Roughly $219 to $499 per month by tier | Roughly $230 to $350 per month by tier | Priced by emails per month, often well under rivals |
| Template design | Best in class, lockable brand templates | Good, large template library | Competent, less design depth |
| Automation | Basic to moderate, strongest on Premier | Solid journey builder, better on higher tiers | Strong workflow automation at low prices |
| Best fit | Design-led brands and agencies | Teams wanting an all-in-one platform | Budget-focused senders with big lists |
Who Should Choose Campaign Monitor Instead of a Cheaper Platform
Choose Campaign Monitor when email appearance directly drives revenue and your team ships design-heavy campaigns every week. Agencies managing email for multiple client brands get particular value from the lockable template system. Choose Mailchimp if you want one platform covering ads, landing pages, and email with a free tier to start. Choose Brevo if your list is large and your budget small, or if you need transactional email in the same tool. Our reviews of Mailchimp, Brevo, and Moosend cover the alternatives in depth, and our roundup of the best email marketing software for small business ranks the whole field. Campaign Monitor offers a 30-day free trial, and you can also compare it against the Brevo plans before you commit.
What Reviewers Consistently Praise and Pan About Campaign Monitor
Praise clusters around the editor, template consistency, and reliable inbox placement, with long-tenured customers describing years of stable sending. Pans cluster around pricing at scale, thin automation on cheaper tiers, and support quality that some reviewers say slipped after ownership changes. A practical pattern emerges: businesses that send beautiful, planned campaigns to an engaged list report high satisfaction, while businesses that want behavior-triggered automation sequences report outgrowing the platform. Match the tool to the campaign style, not the feature checklist, and the decision gets easy.
The bottom line: Campaign Monitor is the design-led pick, and its template system plus deliverability pedigree remain genuinely best in class for brands where email appearance matters. The trade-offs are pricing that scales steeply with subscribers, no free plan, and automation that trails the field. If polished campaigns are your brand, it earns its premium; if automation depth or list-size economics lead your decision, Brevo or Mailchimp are the stronger options we compared.
