Sources: Campaign Monitor list prices in USD, billed monthly, from its pricing page on October 4, 2026. Constant Contact's pricing page blocked automated checks that day, so its plan prices and send limits come from a search snippet of that page and are labelled as such; its trial, refund, automation, and support details come from its own knowledge base and support pages. Constant Contact also raised prices for existing customers on August 2026 invoices, so older figures you find elsewhere may be out of date. The Trustpilot row counts only reviews Trustpilot labels organic (written without a link or invitation from the company), from our pull that day; samples are small and the windows differ. Constant Contact's G2 figure comes from G2's search listing. More on our methodology.

Agencies and support
Campaign Monitor is built to run email for other businesses. Each client gets a sub-account under the agency login, clients can log in to their own campaigns, the app can carry the agency's branding in place of Campaign Monitor's, and the agency can add a markup to each client's bill. These are on Lite, Essentials, and Premier. Constant Contact has a partner program with an umbrella account and client sub-accounts; it does not publish a white-label option for email.
