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.

Klaviyo

  • The free plan caps active profiles at 250 and sends at 500 emails a month
  • Pricing scales with stored profile count rather than with messages sent, so an unengaged list costs the same as an active one
  • SMS is metered separately, with only $5 of mobile messages included on the free plan
  • Paid tier prices are not published on the pricing page and depend on profile count
