Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Campaign Monitor
- The Lite tier caps monthly sends at 2,500 regardless of contact list size, so a list of any meaningful size cannot be emailed even once a month without exceeding it.
- Unlimited sending only starts at the Essentials tier, so the cheap headline Lite price is not comparable to competitors that offer unlimited sends at their entry tier.
- Its e-commerce-specific automation (abandoned cart flows, predictive segments) is less developed than Klaviyo's, making it a weaker fit for retail-heavy senders.
- As part of the Marigold group alongside Sailthru and other acquired brands, product roadmap priority is shared across a portfolio rather than dedicated solely to Campaign Monitor.
- Pricing multiplies on two axes, contact tier and plan level, so estimating total cost requires checking both dimensions rather than a single number.
Terraform
- HCL syntax requires learning a domain-specific language with limited GUI alternatives
- State file management is complex, especially at scale with multiple workspaces
- terraform import workflow is fiddly and must be done one resource at a time
- No native error handling or try-catch capabilities like traditional programming languages
- No automatic rollback capability - must manually delete and re-run if needed
