Campaign Monitor Review (2026)
Growth tools only earn their keep if they move a real number — leads, conversions or revenue — not just activity. So where does Campaign Monitor actually fit? Most people land here while weighing it against Mailchimp, so that is the comparison this review keeps coming back to: does it do the job you actually need, without charging you for the parts you don't?

What Campaign Monitor does
Email campaigns with strong templates and client-friendly management for brands and agencies. Priced per contact rather than per send: Essentials at 10,000 contacts runs about $89/month, so dormant subscribers bill like active ones. Automation depth is lighter than dedicated platforms.
Pricing (2026)
Contact-based (2026): for 500 contacts roughly Lite $12-13/mo (send cap ~5x contacts), Essentials $29-31/mo (unlimited sends), Premier $159-171/mo; the same tiers climb steeply with list size (Essentials at 10k contacts ≈ $89/mo). Annual billing saves ~25%. Plans change — always verify the live price on their site.
Correction after re-checking: Contact-based, read on the vendor pricing page in EUR with the monthly-billing toggle: at 0–500 contacts Lite €12/mo, Essentials €29/mo, Premier €158/mo; at 5,001–10,000 contacts Lite €109/mo, Essentials €168/mo, Premier €277/mo. Lite caps sends at 5x your contact count (2,500/month at the 0–500 tier); Essentials and Premier are uncapped. Annual billing takes 10% off, not ~25%, and the annual discount does not apply to agency or multi-team plans. (re-verified 2026-07-31)
What the pricing page doesn’t say
You pay for contacts, not sends — so a large, quiet list costs the same as a large, active one, and dormant subscribers are literally a line item. Clean your list before comparing prices anywhere. Campaign Monitor's strength is polished, agency-friendly email; its automation depth is lighter than dedicated marketing-automation platforms, so know which of the two jobs you're actually buying.
What buyers report about Campaign Monitor
Recurring themes from G2, Capterra, GetApp and Gartner Peer Insights, read in August 2026. We have not run Campaign Monitor ourselves, so this is other buyers' experience rather than ours. We summarise it here because the complaints are usually the part a vendor page leaves out.
- • The interface is clean and the templates make good-looking email easy — that is what reviewers consistently name.
- • Support gets good marks from most reviewers: quick, personal and staffed by humans.
- • Price climbs sharply with list size and is the main reason teams leave. At 25,000 contacts, Essentials runs about $199/month against roughly $65 for ActiveCampaign or Brevo.
- • Automation depth is limited and there is no landing page builder.
- • There is no free plan — only a 5-subscriber sandbox.
- • A minority report slow support, no live support without paying extra, and difficulty reaching anyone. Lite from $13, Essentials from $31, Premier from $171 at 500 contacts.
When the paid plan is worth it
The first real decision is send volume, not features. Lite caps monthly sends at 5x your contact count — 2,500 emails at the 0–500 tier — while Essentials removes the cap. At 0–500 contacts that step is €12 to €29 per month on monthly billing, so anyone mailing a small list more than five times a month has already justified it. Premier is a different calculation: €158 against €29 at 0–500 contacts, but €277 against €168 at 5,001–10,000, so its premium over Essentials narrows as the list grows. It buys phone support, send time optimization, pre-built engagement segments, template management for teams and the included website builder, which is otherwise a €9 per month add-on; on Essentials only the engagement segments and the website builder are listed as purchasable extras. What no tier changes: the bill follows contact count, so a dormant list costs what an active one does, and no plan lets you keep a Gmail or Outlook From address — on every tier an unauthenticated address is rewritten to an account subdomain.
How to actually use Campaign Monitor
Nothing goes out under your own domain until it is authenticated. Campaign Monitor's stated policy is that mail only goes out from authenticated domains: free webmail addresses cannot be authenticated, and an unverified From address is rewritten to an account subdomain such as abcxyz.createsend7.com, with replies routed back to the original address. Setup runs through Account settings, then Sending domains, and means adding up to three TXT records — DKIM, a DMARC record, and a recommended SPF include — at your DNS host, with a default TTL of 300 seconds; some hosts require higher values, and a DNS host that rejects underscores cannot be used at all, though semicolons can be escaped. The documentation itself calls this step highly technical, and that is where non-technical teams stall. The list side is quicker: imports accept CSV, Excel, TXT and ZIP files up to 20 MB per upload, with file columns mapped to list fields. Two traps: a column whose first 1,000 rows are empty is dropped, and re-importing previously deleted addresses reactivates them. Importing without permission can end the account.

Campaign Monitor vs ActiveCampaign, side by side
Both columns come from the same place: each vendor’s own published pricing, read on the date shown in the sources at the foot of this page. We do not average them into a score.
The natural comparison is Mailchimp or ActiveCampaign — Mailchimp is the closest general peer, ActiveCampaign wins on automation depth — compare at YOUR list size, since contact pricing diverges fast. Weigh it against Mailchimp on the job you actually need done.

Frequently asked questions
Is Campaign Monitor worth it for a small team?
It depends on whether you have the bottleneck it solves. Small teams get the most out of this category when one clear problem is already costing real hours or revenue; buying ahead of that just adds cost and another login. Price it against the hours or lost deals it removes, not against its feature list, and start on the smallest plan that covers the job.
Who should not use Campaign Monitor?
Skip it if you need deep behavioral automation and CRM-grade journeys (ActiveCampaign-class tools fit better), or your list is large but low-engagement — prune first. Buying a tool to fix a problem you don't have yet just adds cost and another login to manage.
