Where each one falls short

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

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

Shortwave

  • Per-seat pricing increases team costs compared to flat-rate email solutions
  • AI features may require higher tier plans, limiting value for smaller teams
  • Dependency on third-party integrations for full feature depth
  • Learning curve for effective use of AI-powered features
  • Limited customization for AI filter behavior compared to manual rules
