What you give up either way
- Deliverability team and expert deliverability services
- Inbox preview and spam-filter testing tooling
- Access to Campaign Monitor’s built-in integrations catalogue
- Agency features (private labeling, subaccount billing, dashboard widgets)
- AI-powered features (AI Writer, AI Email Booster) and polished UI
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Campaign Monitor, and it does not prove anyone has run it for a month. How we decide.
