The short version

  • Only Omnisend has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Omnisend free plan caps at 250 contacts and 500 emails per month

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.

Omnisend

  • Free plan caps at 250 contacts and 500 emails per month
  • Standard plan is limited to 500 contacts and 6,000 emails per month before an upgrade is required
  • SMS is billed separately starting at $0.007 per message and varies by country and volume
  • Custom pricing only begins above 150,001 contacts, requiring a sales conversation at that scale
