Campaign Monitor is a strong fit if its core strengths match your workflow, budget, and support needs. Use the quick signals below before opening the full review.
Campaign Monitor has been serving professional email marketers since 2004, building a reputation based on email template quality, deliverability reliability, and a multi-client management interface designed specifically for agencies managing multiple brand accounts. While newer tools have surpassed it on automation sophistication and pricing competitiveness, Campaign Monitor remains the preferred choice for design-focused agencies and brands where email rendering accuracy is the primary criterion.
Campaign Monitor's drag-and-drop email builder is engineered for rendering accuracy. The platform automatically inlines CSS styles — converting stylesheet declarations to inline attributes — ensuring that email clients that strip external CSS (a majority of enterprise clients) render the design as intended. The multi-client preview shows the email rendering across Gmail, Outlook (multiple versions), Apple Mail, Yahoo, and mobile clients simultaneously.
For brands with strict brand guidelines where a blue that renders incorrectly in Outlook 2016 is a genuine problem, Campaign Monitor's design tooling is more precisely controlled than competitors. The template library includes professionally designed starting points with layout quality noticeably higher than Mailchimp's free templates.
Campaign Monitor's agency account model allows a single agency login to manage unlimited client accounts, with client-level billing, reporting, and permission controls. Each client account operates independently with its own subscriber lists, templates, and campaign history. This structure eliminates the administrative friction of managing separate accounts or sharing credentials — a meaningful efficiency advantage for agencies managing 20+ client email programs.
Client-level white-labelling allows agencies to present Campaign Monitor's interface under their own branding. Clients who log in see the agency's name rather than Campaign Monitor's — a professional touch for agency-branded service delivery.
Campaign Monitor's 20+ year operation has produced well-maintained IP reputation across major email provider networks. The platform's deliverability monitoring, bounce handling, and unsubscribe management are robust — campaigns consistently achieve high inbox placement rates rather than spam folder delivery.
For established email programs with large sender histories, Campaign Monitor's reputation for reliable inbox delivery is a meaningful consideration, particularly for brands that have experienced deliverability issues with other platforms.
Campaign Monitor's automation covers standard email marketing workflows: welcome series, date-triggered campaigns, click-based follow-ups, and simple multi-step sequences. The automation builder is functional but not sophisticated — multi-branch conditional logic, event scoring, and advanced behavioural triggers are outside Campaign Monitor's current capabilities.
For marketing teams whose automation needs are covered by standard sequences and segmentation-based sends, Campaign Monitor's automation is sufficient. Teams with sophisticated automation requirements should evaluate ActiveCampaign or Klaviyo.
Campaign Monitor does not offer a free plan. The Basic plan starts at $11/month for 500 contacts, with Unlimited and Premier tiers above. Relative to MailerLite ($10/month, 1,000 contacts) and Brevo's contact-unlimited model, Campaign Monitor is not the most competitive on price. The justification is professional deliverability, design quality, and agency tooling — trade-offs that make sense for specific buyer profiles and less sense for cost-optimising small businesses.
Campaign Monitor is the right tool for design agencies managing multiple client accounts and brands where email rendering accuracy and professional template control matter more than automation sophistication or pricing competitiveness. General small business users are better served by MailerLite or Brevo.
Score: 7.8/10 — Best agency multi-client management and email design precision; pricing less competitive and automation depth is limited.
