Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Keila

  • There is no free hosted plan at all, stated as deliberate policy, so unlike almost every competitor there is no way to run a small list at zero cost without self-hosting it yourself.
  • Marketing automation is minimal, with none of the behavioural triggers, journey builders or e-commerce revenue attribution that Klaviyo, Brevo and Mailchimp treat as table stakes.
  • The self-hosted route puts deliverability entirely on you: reputation, SPF, DKIM, DMARC, warm-up and bounce handling are your problem, and a badly configured instance will land in spam folders.
  • It is a small project from a small company, so the integration ecosystem is thin and there is no partner network, template marketplace or large body of community expertise to draw on.
  • Email volume tiers step in fixed blocks, so an organisation whose sending is uneven across the year either overbuys at the annual peak or has to change plan repeatedly.

Novu

  • Free plan activity feed retention is limited to 24 hours, restricting how far back teams can debug delivery issues.
  • Overage on Pro and Team plans is billed at $1.20 per 1,000 additional workflow runs, which can add up at scale.
  • HIPAA BAA compliance and dedicated SSO are Enterprise-only and require custom pricing.
