Campaign Monitor
Campaign Monitor is a web-based email marketing service for managing subscriber audiences and sending campaigns.
What Campaign Monitor is
Campaign Monitor is a web-based email marketing service for managing subscriber audiences and sending campaigns. It includes email automation, audience segmentation, landing pages, and A/B testing. The service lists 250 native integrations for connecting with other tools. Campaign Monitor is paid, offers a 30-day trial, and has no free plan. Its listed plans cover 0–500 subscribers. The Free trial plan includes 500 contacts and 500 emails. Lite allows 2,500 emails per month for 0–500 subscribers. Essentials and Premier each provide unlimited campaign sends and 5,000 transactional emails for the same subscriber range. These stated allowances distinguish Lite from the two higher plans by monthly campaign volume, while Essentials and Premier share the listed sending limits. The maker, Campaign Monitor, was founded in 2004. Choosing among the plans therefore depends on subscriber count, campaign volume, transactional email needs, and whether a trial is sufficient before paid use.
