Is Campaign Monitor a good fit for agencies?
Yes, the best fit among the email tools we checked. An agency account holds client sub-accounts that can be treated as white-label customers, with per-client user access and price markup. You can bill clients directly or let Campaign Monitor invoice on your behalf.
Send approvals, email section locking, template and automation sharing, and unique API keys per sub-account help you control quality across clients. An agency account can switch to a direct account only when it has one client and no markup.
The costs are the contact-based pricing for each client and a G2 score of 4.1 from 732 reviews, which is middling.
Trial the tool on a real client list rather than a demo. Note how long setup takes, which features you actually touch in the first week, and which questions the team has to ask support. That record is the best guide to whether the plan you picked is the right one.
Agree who owns the tool inside the agency. A named owner keeps templates tidy, watches list sizes against plan tiers, and reviews the bill when renewal approaches. Without one, client accounts tend to collect forgotten lists and stale automations.
Set sending rules before the first campaign: who approves, how lists are cleaned, how unsubscribes are honoured, and who owns the sending domain. Clear rules protect client reputation and your own.
What are the integration, security, and support facts?
Campaign Monitor lists 250+ integrations, including Salesforce, WordPress, and Google Analytics. Two-factor authentication is on every plan, and Enterprise states GDPR and SOC 2 with custom DPAs.
Support is priority on Essentials, phone on Premier, and a dedicated account manager on Enterprise. A mobile app was not stated.
Before you buy, ask the vendor for the current plan limits in writing and note the date. Contacts, send limits, seat counts and trial terms change often, and a screenshot of what you were promised makes any later conversation about billing simpler.
Plan a review at ninety days. Compare actual use with the plan you bought, and downgrade or switch if half the features sit unused. Small agencies save most by trimming plans they have outgrown or never fully used.
What integrations, security, and support does Campaign Monitor offer?
