- Link review and spam testing
Cons

- Automation is basic
- No free tier
Campaign Monitor: What You Need to Know
Campaign Monitor built its reputation on two things: beautiful email templates and agency client management. The template builder produces polished, professional emails that look like a design team created them. The agency features let you manage multiple client accounts from one dashboard with white-label branding. If you're an agency sending emails on behalf of 20 clients, Campaign Monitor is built specifically for that workflow.
For everyone who isn't an agency, Campaign Monitor is overpriced for what it delivers. The automation builder is adequate but trails ActiveCampaign by years. The analytics are decent but unremarkable. The pricing starts low ($9/mo) but scales aggressively and charges per campaign on the basic plan. At 10,000 contacts on the Unlimited plan, you're paying $149/mo for a platform that MailerLite matches on features at $73/mo.
Campaign Monitor was acquired by Marigold (formerly CM Group) and sits in a portfolio alongside Sailthru, Liveclicker, and other marketing tools. The acquisition hasn't visibly improved the product. Development feels slower than competitors, and the feature set hasn't expanded meaningfully in several years. The template quality remains high. Everything else feels like it's on maintenance mode.
What The Sultan Likes
Where It Falls Short
What You'll Actually Pay
Basic: $9/mo for 500 contacts, capped at 2,500 emails total. Unlimited: $29/mo for 500 contacts, unlimited sends. Scales to $59/mo at 2,500 contacts, $99/mo at 5,000, $149/mo at 10,000, and $249/mo at 25,000. Premier: $149/mo at 500 contacts with advanced segmentation, send-time optimization, and phone support.
Agency pricing: per-client billing with volume discounts starting at 5+ clients. Margins improve with scale. An agency managing 20 clients on Unlimited plans can negotiate meaningful discounts that make Campaign Monitor cost-competitive for the agency business model specifically.
For a non-agency business at 10,000 contacts: Campaign Monitor Unlimited at $149/mo ($1,788/yr). MailerLite Advanced at $110/mo ($1,320/yr). ActiveCampaign Plus at $139/mo ($1,668/yr) with deeper automation and a CRM. The only justification for Campaign Monitor's pricing is if the template builder and design quality are critical to your brand's email strategy.
Should You Buy Campaign Monitor?
Buy Campaign Monitor If…
Agencies managing email for multiple clients
This is Campaign Monitor's real market. White-label branding, multi-client dashboards, per-client billing, and aggregate reporting make it the most agency-friendly email platform. If you manage 5+ client email accounts, the workflow consolidation is worth the price premium.
Brands where email design is a core brand expression
If your emails need to look like they came from a design studio (luxury brands, premium services, design-forward companies), Campaign Monitor's template quality justifies the premium over MailerLite's more utilitarian designs.
Skip Campaign Monitor If…
Anyone who isn't an agency or design-focused brand
For general email marketing, Campaign Monitor charges more than MailerLite and Brevo while offering less automation capability. Without the agency features or design premium, the value proposition evaporates.
Teams needing marketing automation beyond basics
Campaign Monitor's automation builder handles welcome series and simple sequences. Anything involving conditional logic, lead scoring, or behavioral triggers requires a different tool. ActiveCampaign gives you those capabilities at a comparable price.
Budget-conscious businesses of any size
At every price point, Campaign Monitor costs more than MailerLite for comparable (or lesser) features. At 10,000 contacts, you're paying $149/mo vs. MailerLite's $73/mo. That's $912/yr in savings with no meaningful loss for most businesses.
Stage-by-Stage Guidance
Solo Founder
Running lean, doing everything yourselfNo free plan and aggressive per-contact pricing make Campaign Monitor a poor choice for solo founders. MailerLite's free plan or Kit's 10,000-subscriber free tier serve solo operations far better at zero cost.
Small Team (2-10)
Growing past founder-led salesOnly consider Campaign Monitor if your small team specifically needs premium email templates or manages email for multiple clients. The Unlimited plan at $29-99/mo (500-5,000 contacts) is functional but overpriced for teams that don't use the design or agency features.
Mid-Market (11-50)
Scaling with dedicated teamsCampaign Monitor's Premier plan ($149-249/mo) adds send-time optimization and phone support. But at this price, ActiveCampaign Professional ($149/mo) offers dramatically more automation capability. The choice only makes sense if your mid-market team prioritizes email design over automation depth.
Enterprise (50+)
Complex org, multiple divisionsCampaign Monitor doesn't have a true enterprise offering. Large organizations should look at ActiveCampaign Enterprise, HubSpot, or Marketo. Even agencies at enterprise scale often graduate to more powerful platforms.
Alternatives Worth Considering
MailerLite
Choose MailerLite for better value at every contact tier. Templates are less polished but perfectly professional. Automation is comparable or better. Pricing is 40-50% lower. The sensible default for anyone who doesn't specifically need Campaign Monitor's agency or design features. Read review →
ActiveCampaign
Choose ActiveCampaign if automation capability matters more than template beauty. Similar pricing to Campaign Monitor's upper tiers with vastly more powerful automation, built-in CRM, and lead scoring. The upgrade that justifies its cost. Read review →
Mailchimp
Choose Mailchimp if you want strong templates plus a broader feature set (landing pages, social posting, basic CRM). Mailchimp's template library rivals Campaign Monitor's quality, and the platform does more overall. Still overpriced vs. MailerLite, but more capable than Campaign Monitor outside of agency features.

The Sultan's Bottom Line
Campaign Monitor is a niche product pretending to be a general-purpose email platform. For agencies, it's excellent. The multi-client management, white-label branding, and aggregate reporting are purpose-built for the agency workflow and nobody else does it as cleanly. For brands that obsess over email design, the template builder justifies a premium.
For everyone else, the value equation doesn't work. You're paying 50-100% more than MailerLite for comparable (or fewer) features. The automation builder hasn't kept pace with competitors. Product development has slowed. No free plan removes the low-risk entry point that every competitor offers.
The 6.5 score reflects a tool with genuine strengths in a narrow lane, dragged down by pricing, stale innovation, and a feature set that's been lapped by hungrier competitors. If you're an agency, add a point. If you're not, subtract one.
Frequently Asked Questions
Is Campaign Monitor good for agencies?
Yes. Campaign Monitor is the best email platform for agencies managing multiple client accounts. White-label branding, per-client billing, multi-account dashboards, and aggregate reporting are built for the agency workflow. It's the one scenario where Campaign Monitor's pricing premium is justified.
How does Campaign Monitor's pricing compare to Mailchimp?
Similar at lower tiers, more expensive at higher contact counts. At 10,000 contacts: Campaign Monitor Unlimited costs $149/mo, Mailchimp Standard costs $100/mo. Both are overpriced compared to MailerLite ($73/mo) and Brevo ($25-65/mo). Campaign Monitor charges a premium for template quality and agency features.
Does Campaign Monitor have a free plan?
No. Campaign Monitor offers only a limited free trial. No permanent free tier. This puts it at a disadvantage compared to Mailchimp (500 contacts free), MailerLite (1,000), Kit (10,000), and Brevo (300 emails/day) which all offer ongoing free plans.
Are Campaign Monitor's templates that much better?
For most businesses, the difference between Campaign Monitor's templates and MailerLite's is noticeable but not critical. Campaign Monitor templates are more refined typographically and more design-forward. Whether that's worth 2x the price depends on how much email aesthetics matter to your brand perception.
What's the best Campaign Monitor alternative?
MailerLite for general email marketing at a lower price. ActiveCampaign for better automation at a comparable price. For agencies specifically, there's no direct substitute that matches Campaign Monitor's multi-client management. Some agencies use Mailchimp's partner program, but it's less elegant.
