Campaign Monitor: User reviews & features

Campaign Monitor is an email marketing platform that now operates as "Campaign Monitor by Marigold" — the Marigold ownership is stated on its own site, with the campaignmonitor.com domain unchanged, as we confirmed in August 2026. Its position in our demand ranking carries a caveat: the brand name overlaps a generic marketing phrase, so its measured search volume is likely inflated relative to true brand demand. We have not yet captured its pricing at our normalization volumes; a price level will be assigned when that capture runs.

Scored 0–100 from public evidence: an official MCP server weighs most (40, +5 when hosted), then official agent skills, AI assistant apps, AI-friendly docs and built-in AI features. "Not found" means we couldn't locate it on Campaign Monitor's public pages or the official MCP registry, not that it can't exist. This is context, never part of the Deliverability Score.
