The Campaign Monitor alternative with transactional email and modern pricing
Campaign Monitor focuses on marketing campaigns but lacks a transactional email API and charges by contact count. Sendkit gives you transactional emails, campaigns, and automations in one platform — priced per email, with unlimited contacts.
Why teams switch from Campaign Monitor
No transactional email API
Campaign Monitor is built for marketing campaigns. If you need to send password resets, receipts, or notifications, you need a separate service. Sendkit handles both transactional and marketing email in one platform.
Expensive for what you get
Campaign Monitor charges $12/mo for just 500 contacts on the Lite plan, and $29/mo for Essentials. Sendkit starts free with 3,000 emails/mo and scales with per-email pricing — unlimited contacts on every plan.
Limited automations
Campaign Monitor automations are basic and only available on higher-tier plans. Sendkit includes automations on all plans with flexible triggers, conditions, and branching logic.
No AI agent support
Campaign Monitor has no MCP server or AI integrations. Sendkit has a full MCP server with 40+ tools — your AI agent can manage templates, send campaigns, segment contacts, and track metrics.
