Where each one falls short

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

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

Mailjet

  • Free plan caps at 6,000 emails per month with a hard 200 emails per day limit
  • Starter plan is capped at 2,000 contacts; unlimited contacts require the Essential tier
  • Email credits do not roll over and unused emails expire at the end of each billing cycle
  • Essential and Premium plans both cap at 15,000 emails per month for $17 and $27 respectively, so the price increase buys other features, not more volume
